Well let’s try again, I have been machining for 50 years you name it I’ve ran it, and still learning. I’m retired now.great job.

I Worked cnc for a big corporation one spring quite a few years ago. Couple things I learned: don't use your ungloved fingers to clear chips, those things are razor sharp and will cut you to pieces before you realize it's an issue, the way I see it you wouldn't stick your hand I a knife drawer like that so don't stick your hand in a pile of chips. Second: having a coolant hose is much more effective at clearing chips than having compressed air, both have their places. The last thing I learned was don't call out of work sick, instead show up for work and camp out on the toilet, you'll keep your job and get paid to have diarrhea, though I don't think that applies here.

The thing I learned in my one year of apprenticeship (before dropping out) is that nothing beats your bare hands to remove tiny chips. There are a few rules tho. 1. Remove any bigger chips before you go in with your hands. (Compressed air, brush, vacuum cleaner or, as pointed out by OP, coolant hose.) 2. Don't use force, only lightly brush over the surface. 3. Never, ever put your hands near chips that are spinning or otherwise moving. That's not just a knife drawer, that's a spinning knife drawer. That stuff slices you open in a fraction of a second. I noticed Jeremy does all that in this video like a pro.

Thank you for your inspiration! I began dabbling in fabrication, inventing,and repurposing when I was around 6-7 years old. By the age of ten I had my bedroom decked out with remote control lighting, door opened and closed, stereo volume, channels all mechanically actuated and remote controlled from my bed from R/C cars or other remote control items. Keep in mind I am 48 now so in the late 70’s and early 80’s remotes weren’t easy to tear into without getting the third degree from mom and dad. My father retired as a tool maker of 45years for Briggs(Snapper Power equipment), all the tools books and knowledge gained from him were invaluable. You sir are raising the next generation on a grand scale via the internet. 🤝

KUDO"S to you , Sir. I worked in a dirt floor Machine Shop that had overhead shafting and pulleys that drove the Lathes , Vertical drill presses , and old Cincinnati Milling machines . Most of the Machinists spoke German, Dutch or Italian. Best environment for a kid that wanted to work with hands . I wish you Good Health and Good Luck in the future . You have a beautiful Family. God Bless You .

Jeremy, you absolutely blow me away with your videos. You're a natural educator. I look forward to each new video you release!

Mechanical engineer here: awesome job at explaining every step. I feel like I know the whole process but it’s the details that really mess you up until you try it yourself. Watching your video reminds me why I went into this field.

I wasn't a machinist's apprentice for very long, but two helpful tips I learned were: 1, slide fixtures and vices onto the mill, don't place them. That way if a chip happens to be on the table you'll push it out of the way or feel if one is in the way. If you plop it down on the table you'll never know if there's a chip and you'll just clamp it down. 2, when you're fixturing a complex or small part and you're worried clamps will get hit in the tool path, you can bolt the work piece down with nylon or aluminum bolts and it won't matter if the endmill nicks them a little.

Very cool. Most guys aren't doing all the stages (design, CAM, machining, fabricating, welding) themselves. That's a LOT of hats to wear, and a LOT of skills to have under your belt.

One of the best and most inspirational engineering channels on KZread!

I’ve never before felt better about watching or subscribing to a KZread channel, than this one. 💯❤ This is network TV, quality entertainment. I truly and honestly believe that.

Brother your children are so blessed to have a smart father! You’re teaching them now no matter what they want to do in life they can do it. Great video as always brother.

When you are cutting the first part, rather than cut off the extra at the bandsaw, just have the mill do it. Instead of just contouring the outside of the part, mill away all the material around the part (with a rouging pass, like adaptive clearing if available), then take a .010" or so finish pass around the outside of the part. This will not only be easier on the mill (because it isn't slotting), but will also give you a nicer surface finish. It might take longer to cut, but you make back the time and labor by not having to manually cut it after, and can probably increase your feed rates because you are taking a lighter cut. Just make sure your vise jaws are lower than the lowest machined surface!

Out of all the KiwiCo sponsors I've seen, this sponsorship spot was by far the best. Showing your kids actually playing AND having a blast at the same time AND you are and wife had joined in (with the wife wanting a box herself 😜) was a great touch to the sponsorship. So many others don't actually show their kids, or them, playing with gadgets and having fun. Keep up the great fatherhood, and husbandhood, and live a long and happy life 😎😎

Every time I see your channel pop up you're working on something even more interesting and complex. Good work!!

Welder/Machinist for 15 years who works with artists who build custom 3D printers and robots. Aluminum welds will change the temper of the metal and cause it to get gummy. You said it but cleaning aluminum can never be over emphasized. The thing I say about aluminum is make sure you clean it real well and then make sure you clean it again. A hand held wire brush is good to use before you weld to help break up the oxides and make fore a cleaner weld. Keep up the good work and I love learning from your videos. Hoping to build a CNC table like the one you have.

That crowded shed with motors reclaimed from washing machines is not that far in the past. Suddenly you are building a robotic arm with your CNC in a nice large shop. I've enjoyed all of the videos you have made.

I love your enthusiasm for learning. A bright light. ❤️

Hi Jeremy. Cool project. One tip I might give you on work holding is to think outside the box regarding the vise. A good example is at 14:46 where you clamp onto the two tiny points on that part. Not only is this prone to slipping out of the vise due to low contact, but you also run the risk of crushing features on your finished part. This would be an excellent place to use soft jaws instead of the stock jaws. You can machine a pocket in the jaws with relief for those pointy bits so you are gripping the flat portion between them. It is much more secure and you are less likely to damage your part. Also, since you machine the jaws in situ, you guarantee that the part is held parallel to the table, assuming there are no chips or burrs. I have a small machining channel focusing on instruction for beginners if you are interested. Feel free to contact me if you have any questions or just want someone to bounce ideas off of. Take care and keep up the great work!

You could also add an optional stop between different operations giving you the opportunity to check the G code before starting the next operation. Literally a life saver when proving out a program for the first time.

For sure! Also single block mode can be super helpful when paired with a clearance height and lowered rapids. Basically you get a chance to sanity check the z height the control thinks it’s at vs what your eyes are telling you before you get going. Just don’t run the whole program in single block it’ll wear out the tools and your thumb!

I'd also add full stops (M0 on most controls) are very useful. They can be removed once the program is proven. I used to teach CNC operators that the #1 thing they need to be looking at is the DISTANCE-TO-GO display. There's nothing more important than what the CNC is about to move... Also: add comments to your NC code so you know what's going on. If you can edit your post processor, add the comments there. They're just as important as comments in other programming languages. Keep up the great videos, Jeremy! Cheers!

I'm not a machinist but I like watching your channel because I appreciate the problem solving and learning you share. Thanks and good creating to you.

Setting up a CNC is great for making multiple parts... but for just one, its more of an educational experience than fast, and this was a great educational experience. Each, CNC, and manual shop, has its well deserved place. It sure is fun in the new shop! Jeremy has done well building things up, and getting back on youtube with great content. Getting kids engaged as young as possible is best. 👍👍.

Dude you would definitely be #1 on my list of youtubers to be stuck on an island with. You have vast knowledge in real world applications.

As a professional in the workholding industry, it was so refreshing to hear you talk about realizing how important workholding can be. Too often we have customers bring us parts with datum structures, tolerances, and machining processes that are either impossible or demand very complicated workholding. It's almost never a consideration in the manufacturing process, and often times, comes after they pick machines which causes even more problems. And for a beginner in a home shop, you definitely did a respectable job. My only suggestion, if you really want to maintain your sub 0.0005" accuracy, would be to check your tram after shifting the workpiece when your Z was too low.

Like Weld.com says, make every weld better than your last. You're amazing to watch in all the specialties that your videos cover.

Jeremy, I love your enthusiasm and conviction to learning? You are a man after my own heart. I wish you were my neighbor so that we cold compare notes. I am a retired Electrical Engineer, and I learn something new every day. Thank you for producing these very informative videos. I learn something every time I watch one of them. Keep up the good work!!

You are doing great. I learned NC when I was in high school. I was the first person in the state to link a robotic arm to a CNC machine. Made them talk to each other so each could trigger the other. Setup an automated factory making acrylic keychains with the school logo on it for a fund raiser to support the shop class. That was a lot of fun. Later in life I built a software that generated G code for a laser and a CNC machine. I loge robots what can I say. You are doing just fine. Keep up the awesome projects, your videos are very informative.

I'we just watched 6 or 7 hours worth of videos from your channel.I was desperate to get some info about 3 motors that i scraped from vacuum's(I wanted to make table saw from one of those) and i felt like i found the end of youtube. Because I couldn't find ANY channel that informs you what they doing(at this point I don't even thing they know what they doing).I was blessed to find your channel.I'm sad that vacuum motors aren't suitible for table saw. now I have 3 motors that yet to be used in some future project. please keep up the videos I feel like i have lot of things to learn from you ☺️

Angle, C channel, tube, I beam are never square and usually not straight. Throw a square on them before machining so you know what you're dealing with. Also, removing material from them will cause them to warp and move. Try to remove equal amounts from both sides and if it's really important like this part, remove 80% of the material first all over then go back and finish it. It's pain to set up double but doing that way relieves most of the stress and strain in the material and lets it relax. It will maintain squareness better.

When I have to take my vise or rotary table or 90 degree plate on or off a lot I use these precision ground pieces of HSS that fit into the slots as a key to locate the vise. This doesn't necessarily get it dead nuts straight, but it gets you within a couple thou and you just indicate it in from there. Saves a lot of time in setup each time! HIGHLY recommend!! haha

One tip for dialing in an angle plate. Set the indicator to zero in the middle. Then when you move to your pivot point you just have to move it to zero. Usually in about .001 in two minutes flat.

I literally just finished my CNC and started machining things. You've somehow captured my experience with this video, the struggle is real! We will get it, just takes some repetition.

I'm nearly finished scraping the old goo and chips out of my CNC machine - I anticipate at least a few busted tools at the beginning! Still painful to watch, especially when the tool actually shifts in the spindle - that can't be good for the spindle bore or the bearings - truly cringe worthy!

Your success is inspirational! I remember an early video you made about negative comments and tossing it in. Look at what would have been lost if you would not persevered. Onward and upward!

Can't believe I've only now found this channel, or that you're inexperienced in machining- that part looks great! From my experience in professional shops the only glaring "learning opportunities" are: 1. break/chamfer the edges in the machine! A machine made edge-break or chamfer looks so much better than one done by hand, and it reduces the risk of injury when unloading parts. I've seen many coworkers go to ER for stitches after handling a part with sharp, unbroken corners! Sliced myself a few times too! Did I already mention how good a consistent 0.010" chamfer looks? With a 3 axis mill you can use a chamfer mill to accomplish this or even a sufficiently rigid 90 degree spot drill will do if you don't mind to experiment. 2. several seconds before the feedmill stalled and crashed, the RPM of the mill audibly changes. Machinists do well to listen for changes or anything abnormal. So many disasters I've witnessed were preceded by abnormal noise. In the worst disaster cases the machinist chose to listen to an iPod instead! If headphones obstruct your hearing, I propose that electronic earpro exist which allow for detailed hearing without risk of damaging irreplaceable ears. A hunting store has such a product. 3. as others have mentioned, you should check the tram of your mill after any crash. It's a drag but a later discovery that you have been cutting parts out of tram is even more of a drag. If you crash as often as I do you get quick at checking tram :) +1 on the threadmill, taps just can't beat the ability to adjust the fit of threads using tool diameter/wear compensation offsets in controller. Also nothing quite ruins your mood like breaking a tap off inside a part- which does happen infrequently even with rigid tapping capability. Can be quite a fireworks show as most machines I've encountered do not respond to the feed-hold button during the rigid tapping cycle!

I hate seeing tools being broken, but i love a beginner learning from it. It is worth that.

If you're brushing aluminum before welding to remove some of the oxides, make sure you only brush in one direction so you don't reintroduce the oxides; you don't have to worry about that with post-weld cleaning though. Aluminum oxide melts at 3x the temperature of pure Aluminum, so brushing can help the weld run smoother. You're on the right track with pre-weld cleaning and using an Aluminum specific brush, amazing work!!

I've never had a desire to get into this type of work, but I still enjoy watching how you work through the entire process. Your videos are some of the best at exploring and explaining this kind of engineering. Showing all of the learning moments you experience goes a long way in proving that no one is going to get it right the first time, and gives those who are hesitant to start a project like this more confidence, knowing that it's o.k. if you mess up now and then; just learn what and why something went wrong and try not to repeat that the next time. Bravo to you, Jeremy. I can't wait for the next video in this series.

You might consider yourself a beginner but this is the best explanation and instruction I have heard. I really enjoy your channel. Thanks for sharing!

Also, I'm glad you mentioned the danger of stray chips! They can throw your setup off and force you to take it apart and start over. A common practice when placing a vice or angle plate on a table is to slide it around a little before you bolt it down just in case you missed something. A chip or debris trapped under the vise will likely be scraped off by the t-slots and fall down. It's a last step that might save you some grief.

its always good to tap your work piece down into the vice to make sure it is sitting properly on the parallels.

I just stumbled upon your channel. I am an amature machinist ( maker, tinkerer, etc) and you have struck a chord with me.

Jeremy, you are now the first "maker" I watch on KZread. I love your careful explanations...without profanity or innuendo. Love the fact that your family is central to your life.

On the welding feed rate: if you preheat a part that size it can mitigate the need to change your feed speed a bunch. I'm talking just warm it up to 400 F or so. Amazing project! I hope to get one built in the next few years, but more 3d printed.

Hey man - I’m just catching up on your videos since life has been a bit challenging… I wanted to say JUST A FEW THINGS… 1. I have saved more of YOUR vids than any others for frequent referencing while attempting to learn 1/4th what you know. 2. YOUVE inspired me to begin searching for MOTORS while scouting the “heavy garbage” nights and I’ve amassed quite a variety thus far.. Except, I still feel like I have no clue how best to use them and I seriously wish I could find a more direct and thorough way to learn. 3. Your family is simply beautiful & perfect, but this honestly made TOTAL SENSE to me once I saw them in a video. Your personality is second to none and I envy nearly everything about you. In an inspiring way, of course…. 4. I just had a crazy idea that I thought I’d share: While watching your aluminum machining segments, I found myself GLUED to the screen… Seeing the liquid interact with the shavings, and the blade cutting into the aluminum as if it were a soft wood, it was HONESTLY just like watching one of those “ASMR” or rather “MOST SATISFYING” videos… If you haven’t seen them, check them out quickly and you’ll see that LIKE ASMR, the “satisfying” videos are a genre that has EXPLODED in popularity! It’s where people (no different than you) dedicate an UP CLOSE video angle (or angleS) to something they’re doing regularly already!!! Therein is my idea for you. If you had focused a high quality camera that would allow for excellent slow motion post production, you’d have captured TOP NOTCH footage of something that I’d say MOST people haven’t seen before… The fact that you were cutting into BRILLIANT, SHINY ALUMINUM of course gave this that extra WOW & AWE factor, but I’m TELLING YOU BRO you could make a channel and earn EXTRA REVENUE FOR YOUR WORKSHOP by carefully filming the things you’re ALREADY DOING ANYWAY!!!! Just get beautiful closeups, toss some nice TUNES on the footage from the free YT library, and you’re off to the races my man!!! In fact, this could be THE PERFECT WAY to recruit WIFEY and/or THE KIDS to be “IN CHARGE” of filming that footage if you feel it will disrupt your workflow…. IM JUST SAYING…. If it were me, and I had my life as seemingly “figured out” as you do but was always thinking of ways to find that little extra side hustle, ID GIVE THIS A SHOT FOR CERTAIN…. What’s also good is you DONT HAVE TO attach your likeness and channel to this idea (if you don’t wish to)… of course it MAY help to have your large channel promote a second channel, but I’m sure there could be some downsides to it to consider as well… Either way, MOST LARGE CHANNELS have second & third “backup” channels OR just supplemental channels that are “spin-off’s” of their primary… For example, you’re known for THIS CHANNEL, but perhaps you’ve noticed that your audience is mostly middle aged people like me and that you receive A LOT of compliments on your family or REQUESTS to include your family MORE OFTEN…. So you’d create a “VLOG” type channel perhaps, where your daily routine is shared with your audience… OR (and I know ID WATCH THIS, because there ARE HUGE CHANNELS for JUST THIS like @Mike The Scavenger ) how about vlogging while you FIND YOUR DISCARDED TREASURES!!! The list of IDEAS are actually endless for a guy like you and I sincerely wish you the very best and want you to have the workshop of your dreams… This is the only reason I’m trying to convince you to expand your horizons JUST A BIT, little by little, and see if it works!!! You can’t win the game if you don’t play it!!! I just KNOW FOR SURE that with your personality and camera presence, you could even have a separate channel for every time you DISASSEMBLE something (tutorials, “tear downs” etc) - or you can have a LONG FORM channel that supplements this one where you ELABORATE on the projects you show here (for those who wish to see EVERY SINGLE BIT of what you’re doing, which I know id also watch if it were a project I was interested in!!) I hope this reaches you, and I’ll keep wishing that a clone of you moves in nearby so I can find someone to pick and create with!! Haha 😂 - if you would like me to elaborate on any of this, want to kick this around, or need adviCe on how to safely go about this, I’m absolutely here for you bro… you can email me at - protonmail - D0tt - C0mm - just add my YT screen name to the front and that’s me!! I do have PLENTY of experience dealing with LARGE channels like yours as well as a pretty sharp eye for seeing the things that will or won’t work out…. So if I can be of any service, I’d be MORE THAN THRILLED to trade “help for help” with you. God bless my man. ✌️

This is so awesome 👌 if only the kids of today were like you This country would be awesome. Excellent work 👏 👍

Whenever the stock is too small to clamp down and leave the face accessible to machining You can consider welding on a tab of materiel that can be ground or machined off later.. I like your teaching style , just informative and joyful.

You are a natural. I'm really impressed that you are teaching this to yourself. Showing your mistakes is helpful to others. Salute! I will give you a tip or two. Do the first run with the Z zero set high enough that the lowest move won't hit your workholder, and run it watching for gross endmill-breaking errors. Then again with Z a the correct place without the stock in the machine. If you don't see any big problems you have a good chance of no crashes. You're right, workholding and order of operations are big parts of CNC machining. Think through a few approaches before you commit to one.

I'm new too but a couple of thoughts I had: - Most aluminium stock you buy is heat treated and has internal stresses as a result. When you remove material, those stresses can distort the part. That means, for example, you can mill a flat plane, then when you take the stock off the machine, it'll have a bow in it. - You need to clear your chips! If you let chips stay in the cut like when you cut out the supports, the tool has to cut them a second time, which makes it wear faster. - In Solidworks, the Volumill toolpath is really nice for clearing a lot of stock.

I have been a tool maker/machinist for over 18 years, you are doing great. Kudos on learning g-code, in my experience, this was also a great help in my abilities. As far as better holding for that angle, more clamps, and some support under the far edge will help with flex, maybe a block with jacks (if you don't have jacks, you need some) on top. Sometimes you have to machine custom blocks or jaws for vise to hold just right. Also finish cuts are vital for accuracy (I am assuming you already know that). Overall I think your machining skills are great for the amount of time you have been doing it.

Thank you!... and Machinist jacks are on my purchase list!

!!Beginner for life! As long as you thirst for new education and skills, the slope towards mastery is steep.

my advice with the machining is always start light on the first pass. I would aim for .010 of material to be removed on the first pass so if you do run into a high spot you are not overloading the cutter. The portion where you are machining the bracket, I would clean up one surface, and then flip the part to machine the second backside of the bracket with the surface that was just machined going on to the surface of your work holding device. Doing it that way would give you a surface that is perpendicular. The idea would be similar to when you are trying to square up a block. you want to make a surface that you know is flat, then place that surface on your parallels in the vice, then machine the opposing surface from that. Doing so in that order would guarantee that those two surfaces are parallel with each other. I'm no expert machinist, just worked as one for a couple years while I was in college getting my engineering degree, but that's how I would of tackled something like this!

a little bit of advice from one of the last shops i worked at, was always dry run your program, and also setting your G54/work offset, 3.000" above the part(sometimes depends on the Z height limit of the machine, or how tall your part/setup is...), so that way you can see what the program is doing, and then either "single block" your movements through sketchy, or tight areas, or even feed hold, and stop the spindle and take physical measurements in relation of tool-to-part/"distance to go". Sorry if others have mentioned this before. but its something thats saved my butt from crashing a few times. oh and obviously turn your rapid rate down depending on machine 25% rapid or less. love your channel, and hope this info helps save a little heartache of hopefully not crashing as much, cause it will happen eventually...

I watch a lot of videos on KZread. I have to say you have a unique channel with very good explanations and lots of great content!

Nice job👍 As a Solidworks designer and 5 axis mill, and lathe programmer and machinist, you're doing amazing work. Very few understand the time and skill required to go from concept to finished product. Especially when doing it all yourself.

Your experience with G-codes reminded me of mine in 1979. We had to use 8 bit paper or mylar tape to transfer programs to the machine then. Fun to watch your projects. Awesome scenes with the family!

I'm a 30 year design engineer and I am very impressed -- keep up the great work Jeremy.

I am so inspired by your humble and effective way of thinking! You one of a kind, I hope your videos will inspire a new and old generation of makers. Keep up the awesome work.

When I started woodworking professionally (which is also when I started woodworking at all), it took some time for me to figure out how much bigger my stock needed to be than the final part. I kept running out of wood as I milled out the warp/twist/etc. So you're not alone!

I think you need a machinist jack badly. Loved tbe way you take the problem and get through solutions. Machinist for 12 years and just today i had to get to machine a break die for fold bending SS 304 1mm sheet. Got town with that. Good viedo mate

I have added machinist jacks to my list of items to buy!

Your infectious enthusiasm and skill conveying information about these super complicated concepts keeps me coming back for more! I've always been fascinated with robotic arms and watching you build one at this scale is awesome.

I love to watch your videos even though they are of no practical use to me really. Thank you for your enthusiasm, skill and clear use of some high-level language!

You have absolutely amazing mindset and attitude

It’s great to see your channel subscriptions going up so much over the last couple years. Great work you deserve it!

Jeremy here's a little trick I learned from a machinist, remove all but one of the cutters on the head which makes it act almost like a fly cutter and helps/stops chatter.

Smacking the jig, whilst your DTI is still in contact, sends shivers down my spine. Grind the oxide off the ally just before you weld it.

One thing I haqve always said is that engineers and designers NEED to assemble the thing they designed..it's amazing what you can learn.

Fellow machinist of 10 years here. I've learned a lot about electric motors from you and if you ever have questions pertaining to all things machining just inbox me.

Just started watching your vids, "so cool" nice to see an engineer tackling the entire process and understanding what it takes to build a thing rather than just designing it. I am a fabricator in a welding shop, also the boss. I struggle with the engineering part everyday but manage to fumble thru. One word of advice for welding parts, get a ac dc tig welder it is way better for small parts. Thanks Jeremy for sharing your knowledge with us.

When my setup is kinda precarious with more overhang and lack of support than it should have I tend to go for smaller diameter cutters(less force on the work-piece) and just accept more passes to complete the part, I also have a 45 deg. chamfer and facing mill with square tungaloy inserts that are much sharper than your typical inserts and that thing is amazing(so is the finish) for jobs like this...

Yeah, your not a beginner. You've already passed 99% of so called "master machinist" by having the motivation and interest you have. Good job J!

Yours is one of the VERY few channels I actually subscribe to, and this video is one reason why. I really like your thought process. The way you look at a problem and say "how can I solve this and further my own knowledge at the same time?" is brilliant and something I am trying to learn better myself. Thank you for the continued inspiration. Now, back to the video!

Work holding is everything.

Thank you for making these videos! It is rare to see such expertise so well presented in a KZread video.

Very cool man. Turned out nice! A couple things I'd suggest would be to look into your ramp in on plunging an endmill, seemed a bit aggressive but may just be because footage was sped up. Also, if you can get away with not using your spindle for depth and use the knee, you'll get less chatter and less machine wear. But if that's what you have cnc'd or if you need the clearance for your chip guard I totally get it.

Great video Jeremy! You have a lot of natural talent. A couple of things that help with MIG Aluminum, first like you said 'very clean material', helium is your friend, and pre-heat the aluminum pieces before welding may help with consistency of feed. Again, you got talent and great family friendly content.

I didn’t consider preheat. Thanks for sharing

this really made me really respect the machining process. silly me I thought all I had to do was to do my CAD model generate my G code and put a block of aluminum in a glass case upload my code start my machine and go to bed and the next morning my part is ready. this is really involved I did some basic machining in school as an electrical engineer you are not taught that much. you have inspired me to get my hands dirty

Work holding an art in and of itself

I have very limited space, and recently built a small 0.2HP hobby desktop CNC mill. It’s small but very rigid, so I can cut steel with it. This video was unexpectedly relevant to me because you’re solving the same problems that I have to solve even though the parts that I make are 1/10th of the size of yours. The quality of your content continues to increase, really glad you’re here to help the rest of us!

This is so cool! You are awesome for attempting such an ambitious project and double awesome for documenting it so well for the rest of us to be inspired by. Thank you and keep up the good work!!
