I'm surprised the various tooling companies haven't sent you even a modest set of carbide drills to try; your audience surely has many who could use them too.

Ebay $56 Aud, my first go at carbide 4 flute end mills, 8 piece, 2mm-12mm, no 7/9/11mm. SUPER impressed, sooo sharp and hard n heavy. The shavings off side milling steel wouldn't brush of my hands, like I'd grabbed a echidna. One(1) HSS 6mm endmill in my town in NSW is more than $60. Definitely give the ebay ones a go. The brand I ended up getting sent was PREDA. I'm stoked on them and will be getting a spare set, although they still feel dangerously sharp and no chips with lots of use. My HSS 2 and 4 fluids have a place, just not the go to in my BF16 mini mill with MT3/ER32 arbour and collets. Love the carbide❤. My mill has no quill dro, the next size up does, I'm looking at a retro fit with one like just installed, super useful vid, cheers mate👍👌🇦🇺

You should have slowed the speed down, it may not have work hardened the material

Would LOVE to see PM Research offer a PM-728VT milling machine with QuinnPro upgrades based on all the little "niggling" details that you have solved.

Great improvements! And, as always, I laughed out loud at "...because SHUT UP! That's why." Thanks, and Meow to Sprocket.

I do love that comment as well.

Thanks for the reminder to be accurate where accuracy matters, and not chase tenths when it doesn't.

Since I started my hobby machining journey, and subscribing to your, and many other hobby machining channels, I got a job at a very large company with a plastics division. Not moulding. Machining. I work at a plastics machine shop, as the toolmaker. I get to cut all kinds of materials that I could never hope to afford in my home shop including high performance alloys for work/toolholding and the parts themselves which, despite being plastics, are more difficult to machine than most metals. I can comfortably take .400" to .600" (at 100-300ipm) DOC on our smallest mill in 6061 but some of the plastics we work with I dare not exceed .050" It really puts into perspective the massive chasm between hobby machining and production cnc machining and watching this video I have to remind myself that even your fairly large "small mill" isn't even 1/100th the weight of our smallest mill (Haas TM-1) and that .060 in steel for these little buggers is a decent cut. Despite all that I still come back to my little 21"x7" manual mill and cut stuff up at home. Thanks for the content and keep on keepin on

Another trick for hard/hardened steels (which we use to open out ring gear holes in hardened gears, and to drill out stripped set/grub screws), and is also fairly cheap, is masonary bits - grind the tungsten tip at a sharper point/edge and they can chew through a lot of hard materials

@georgedennison3338

11 ай бұрын

The edge on masonary bits is intentionally dull so the bit can grind through the rock or composite, instead of trying to shear, as sharp bits do in metal/wood. I've been using a worn out diamond masonry saw blade from my wet tile saw in an old Skil 77 worm drive as a metal saw for 10-15 yrs. Added an air hose for cooling, & it's a slag makin' monster. Cuts fast in 1/4" & under, maxs out at 3/8+". Even SS!

Masonry drills are great for drilling in Lexan and other hard plastics, too. Just don't expect a real round and precise hole.

Cubits, barleycorns, bath measures, sheckels, stone, and [of course] apples for measuring Smurfs...yes. LOL. Metric double devil-horns and Imperial double fist-pump!

Opening line got me. Hahaha. You'll have to update us when you pull that quill DRO bracket back out and put a hole in the top for electrical hookup for a LED work light inside there. Or perhaps a mounting hole to bolt in a bracket for something (mount for a magnifier, a camera you don't mind sacrificing, FogBuster air/mist nozzle, etc). Always a pleasure, stay safe and have fun.

@oldfarthacks

11 ай бұрын

Why not a work light and a camera? One of the really cheap little box ones would fit with room to spare. Just mount a glass cover that can easily be wiped off and replaced when it get broken.

Oh dear, me again. Most of these cheaper capacitive DRO scales use a relative position indicating system. They know how far they have moved but have no idea where the scale zero is. To overcome this to some extent only the display is powered down - the position memory is kept active. So the scale uses some power even when apparently turned off. The more expensive high end models use an absolute position system. They turn off fully and know precisely where they are when turned back on. Since almost everyone manually zeros their scales when switching on it would be perfectly feasible for even the cheap ones to turn fully off - I'm not sure why they don't.

Another excellent Quinn video, once again perfecting the combination of intellect and wit with Just the Right Amount of cheeseburgers!

That was a long list of good luck in that install. Apparently the gods of fate like your channel too! 😂

11 ай бұрын

It's really not that hard; imperial machinists use the basic idea of metric all the time when they speak of "thous" and "10 thous": Scaling the unit by factors of 10 is exactly what metric do. In fact, one could ague that instead of speaking of thous" and "10 thous", one should measure in "milli-inches" and "(100s) micro-inches"

@asciimation

11 ай бұрын

@@troelshansen6212 That makes sense now you mention it. But the trouble when you have a metric trained brain is I always think of a thou as 'about .025mm' and that '1mm is about 40 thou' which makes it tricky to do precision machining!

Thank you so much for the cubits conversion. You're always thinkin'!

Hey Quinn, I made a adapter that holds a shop vac 'crevice tool' to the head of my mill. Now I just turn on my shop vac, adjust the vacuum to be close to the end mill, and suck up most of the chips as I mill. I think you would really like this. It's nice for deep pockets and also if you are dealing with something powdery like cast iron. It keeps my shop cleaner and keeps stuff out of my lungs as well.

@imkds55, I'm just getting my new PM 932 set up in my shop. Haven't finished with the electrics for it yet. Soon hopefully. If you've had problems with the quilt DRO then maybe I should investigate a fix before I get this beast commissioned. Couple of other items that make it obvious that this is a Chinese mill as against the Taiwan made PM version Quinn has. Any other short comings you've noted. Any pointers would be appreciated. Mine has the power down feed. It's a seperate added on gear box but I have no information about it, parts list etc. PM doesn't either. In fact I've been a little disappointed with their after sales service despite glowing reports from other users. Maybe it's because I'm in Canada. Hopefully I won't have to rely on them.

A quality life improvement and and and a machining quality upgrade / improvement. 👍

Cobalt alloy works great on stainless, and they are both cheaper and stronger than carbide, especially if they are TiN ed. That being said, HSS will drill stainless pretty easily as well, but you need to get the speed way down, like 1 - 200rpm or less on a 1/4 drill and keep the pressure up , you want to be hanging off the three arm handle on the drillpress or spindle. STub drills help for this because they don't bow as much under the axial load.

Great video. I mean, nothing got pickled, but still, great video.

Best of good luck in passing the horseshoe

Regarding digital tools without auto-shutoff, I do have a set of digital calipers from iGaging that does not power down automatically - and the power draw is so small that the battery has not needed replacing. I do manually turn it off when I think of it, but more often than not, I find it still on from last time.

I learned something from this video. If all the holes are in the wrong place, the errors cancel out. I'm going DRO shopping!

Thanks for entertaining me, Quinn. Also, thank you for educating future machinists. Thus, keeping our craft alive.

Now I can’t un-think or un-visualize that horseshoe.Thank you and the internet.

That explains the metallic clang i heard the other day while on the toilet after i had a steer tire go down, guessing i cracked a rim going through St Louis......... Years ago, when I worked for Stoughton Trailers, i hated having to install roll up doors in trailers with stainless steel rear frames. Try finding an air drill that runs slow enough to not burn up a bit, and then try to punch through all the holes that the idiot before had work hardened. All whilst using high speed steel..........

OMG!!! I replay the opening over and over... HILARIOUS!!!!

I really love your videos. They have the right balance of everything; and mostly knowledge content and pleasure as if viewer would actively participate at building the things you do. I wanted to say also what @nt2080 already said; poor man's carbide masonry bits sharpened with small diamond Proxxon disk/hand tool. Proxxon mill-drill jig has good repeatability for angles and travels. Though I made limited use of them (carbide drills), they did the job when it was necessary in tough materials. Even (though I don't recommend pushing luck against purposed tools) sharpened carbide tips of a large masonry crown and used it in multi- fly-cutter style. For aluminum stock, off course.

I like how an imperial measurist referred to old time measurements with nary a hint of irony. 😊

for those wondering about that old timey measurement for leather... 4oz for example, that means a sq ft of that leather weighs 4ozs. thge reson for this method is that different tanning methods provide different material properties and thicknesses and the best method for determining strength is density of the hide, more so than the thickness.

Great video, love all the upgrades.

Great fix for the quill DRO !

Been wondering about the quill dro on my PM25 similarly. Mine has though what i had assumed was a solid block of metal instead of a sheet metal bracket. But upon removal it turns out it’s actually a rectangular block of gray nylon or similar. Machined a direct replacement out of steel and now it’s rock solid. So thanks for that inspiration!

hail the carbide drill bit

Stainless has a steep learning curve, you did well to complete the mounting holes!

That was the oddest, but funniest intro yet. The first few minutes I was just thinking "horse shoe" up where? What?

This video is exactly what I needed to see. I will start the quill mod on my 728VT today. Thanks for posting!!!

Hey, great upgrade. Don't know if it would help here, but a good trick to have up your sleeve is take a masonry drill bit, sharpen it (clearance behind the cutting edge) and you can drill harden steel. It might need to be done a couple times, but ive seen it done on KZread car channels when they need to drill say input shafts on gearboxes etc.

I had exactly the same experience drilling a stainless scale for my quill. The only thing that would touch it was carbide. Tough stuff.

Well that was very well timed 😀. I'm currently fitting the iGaging versions of these scales to my mill. I need to shorten one of them. They're described as "hardened stainless steel" and I was unsure if I would be able to use my bandsaw to cut them. Well the answer is yes! I don't at the moment think need to drill them but if I do - now I know I'll need a carbide drill. Thanks as always for your videos.

We need googly eyes on those dro screws

Ive never seen u this happy

Just want to say, I completely enjoy your videos, and make sure I don’t miss a single one... thank you

I'm a new hobby machinist and I have learned tons from you! thank you for making these videos!

Hello Quinn, I sharpened a 3/16" masonry drill bit and drilled a hole in a used power hack saw blade, went through easily, that really surprised me. Good job on the milling machine. 😷👍👍👍👍👍

Well done!!

Hi Quinn. I needed to drill some small holes in the side of a Mill support cabinet. I don't know what steel sheet it was but my HSS drills would not touch it. I resorted to carbide and it was night and day different. Well worth the money!

nice improvement, good job, go on.

Fantastic improvements to an already fantastic machine, I never noticed the mount bracket movement in my quill pro I must check it and do your upgrade if it is required, thanks for the wealth of wisdom cheers.

I just ordered one of these machines (yesterday) after watching a handful of your videos about it. I was going to get the pm-30v, but decided to go with the "precision" features of this one instead. I am hopeful that I made the right choice! - And as a side note: I'll be damned if I am going to use something battery powered on a brand new 4000$ lathe. even if it requires hacking up the device, I'll be putting a dc power supply on there somewhere to run that quill DRO. I had a similar situation with the laser alignment device on my drill press, which used batteries which would go dead in about 24 hours if left on. I just spliced in a 5v dc adapter behind the work light switch and powered it from that instead.

Never mind. I googled it. Its a "Luck" reference... although, in your case, I think your luck ran out, didn't it?

I have a Chinese no-name vertical DRO on my milling machine. This one does not have auto-off feature. This means when I forget to turn it off, I drain the 2023 battery faster than desired. It is SO easy to forget to turn this DRO off. It also has the soft rubber buttons which are meant to contact tiny micro switches on the board. These are often a hassle to get the button to work, especially when trying to turn it off.

Thankyou 👍 wimet carbide tipped drills are very good
