The thing i like most about Abom is aside from the lifetime worth of knowledge and wisdom he is willing to share, you can just tell he loves what he does. Dude gets genuinely excited talking about tools and machining. That enthusiasm and humble love of the work is, imho, what separates those who are good from those who are great at what they do.

Thanks for the videos. My Dad passed away 8 months ago and was a tool maker by trade for 37 years. We had 43 good years together and I always wanted to learn from him. I now have a lathe and a Bridgeport and am determined to learn. Its cool using my Dads mics and calipers when working out in the shop. Your videos are great. Keep up the good work.

Thanks very much. This explained a lot of what I needed to know as a beginner hobbyist machinist.

Adam what has taken 10 years to learn by trial and error, you have shared in minutes... then you moved me ahead another 10 years just explaining the feel and sound and color. I don't comment much, but I do make production parts from brass that are part of how I make a living. Thank you, you and Mr. Pete have taught me so much about machining.

Thanks for the video, the basic informational ones may not be a favorite of every viewer, but for someone trying to learn I have to say I appreciate the effort.

What a chunk of great information in that video! I'm just getting started in machining and that was invaluable. Thanks! Dan

Thanks Adam, great video. Good tips for us home shop guys. Thank you so much for all the great content you put out for us.

Thanks, Adam! I've been struggling with parting for a while and this is all really good advice!

I love the projects, dont get me wrong, but shop talk where all your knowledge about stuff comes out directly = gems of knowledge. I love hearing the wisdom of someone whos been at it forever, because you hear about the common pitfalls and the fixes, that one might only learn if they were lucky enough to work in a shop. On another note, hope your contractor problems got sorted, I'd do it for you at cost if I were in the area. Anyways, love the vids. Thanks Adam !!!!

Hi Adam ! That's the kind of videos I like ! Instructional and very usefull ! Thx for sharing !

Great information. Thanks for sharing. I always learn something from your videos. Great job Adam.

Thanks Adam. You've answered a number of questions that I've been unsure about. As always ... terrific content!

Many thanks for doing this video Adam. I remember always struggling with chatter when parting in the lathe when I started out in tool and die way back in the late 1970's. I left the trade to go into tool design and then machine design. Finally, I now have my own 9 inch Southbend lathe at home and once again am struggling with parting tool chatter.

Hi Adam. I seem to recall many years ago at school the parting tool was run upside down at the back. Presume to try to keep the chips from jamming up and stop them flying. Had to use shims to center the tools as well !!!!

Good stuff Adam, super helpful to us rookies. Thanks

Good video Adam, it answers a few questions I had. Keep 'em coming :)

Stopped in middle of your video to order the tool height gage as that has been one of my biggest challenges, hopefully it will become routine. Thank you for the time you spend passing on your knowledge.

Great video. I had some bad luck so I punched in high speed steel parting and my dude popped up. By the end of watching your video I was already at my lathe with the couple adjustments like stick out and lathe speed. World of difference and another piece of the machinist puzzle. Thanks

Thanks for all of your good advice. I've recently begun hobby machine work with an old Atlas 10 inch lathe and a small Benchmaster mill (made back in the 50/60's in Los Angeles of all places) and I really benefit from your videos. Thank you for your time and effort.

Thanks Adam, now I understand the difference. I'm a newbie and learning this has been alot of fun. BTW, Always enjoy the videos.

Hi Adam, You have shown that, while you can learn a great deal from a book, there is a great deal more that only comes from experience. Knowing your machine, the tool and the material and how it performs varies so much. The old rule of reduce the speed and increase the feed and vice versa is spot on and applies not only to parting but any cutting operation and it's a matter of finding that sweet spot. Aluminium is a material that I find needs lubricant particularly in parting or milling slots because of the rapid heat build up that can occur running dry and potential to weld to the tool, sometimes with devastating results. I've seem some disasters from CNC milling centres where quite large tooling has been shattered and welded into the workpiece - an expensive outcome. Keep up the great work.

Thanks Adam, this is a really useful video for we hobbyists with petite machines. I've read lots on parting theory and learned to work within the limitations of my small machines, but to have one of your long-form videos is really handy, because there's something really informative about the way you say whatever's on your mind about a machining topic that's really informative, and provides a whole lot of subtle details I haven't found anywhere else. Love your work, good sir.

Thanks Adam. When I started out, I found that I was over cautious (having broken several parting tools), the problem was a combination of not squaring up accurately enough, not using enough tool pressure and lubrication when making the cut. The best advice I received on this was to be confident in the operation - check the tooling is square, always use a firm positive cutting pressure (or it chatters) and lots of oil. Using the auto-feed was also helpful in building confidence as it maintained constant pressure when I would otherwise chicken out !.

Great video! Thanks for passing your knowledge on!

Good one, Adam, and an extra show during the week! Those dovetail type HSS blades really help on the older machines with plain bearings. Sure makes a difference when you can get them really sharp. Good advice on the cutting oil for the HSS parting tools, too. Between getting them sharp and keeping oil on them they make a difference for smaller or older machines. Thanks for another show!

Thanks Adam. This very subject is one I was unsure of. I am usually successful in parting on the lathe, but it's not without its issues. I think you have answered a lot of the things I was unsure about, such as knowing when to use what type of parting blade and at what speeds. As always, you da man. LOL

Thank you for this video. I was dreading to try parting because of past experiences. I followed your advice and parted 3 inch aluminum tube with no problem. I ended up with the thinnest band of aluminum you could imagine . I keep it as a trophy.

I have always struggled with parting off. Thanks for the tips Adam.

Gotta love your vids Adam! Keep up the great work

Thanks for your great introduction Adam. I've had good success with 3/32 x 5/8 high speed blades in my Aloris tool holder using a generous flow of oil from the sump. Lubrication is critical on steel and speed can be too slow as well as too fast. This type of tool holder clamps the blade at a slight positive tilt so no need to grind back rake on the top. Generally the thinner the blade the easier it is to control chatter.

This video is well-structured. Nice job.

Adam that was Great Im just getting ready to get a lathe and these basics vids are great thanks man keep it up

realy useful tips Adam :) Even my teacher I had in CNC school didn´t teach me those differense between high speed vs carbide.

VERY INFORMATIVE. I AM A WANNA-BEE MACHINIST AND THIS VIDEO WAS VERY HELPFUL. I AM DOING A LOT OF ALUMINUM AND I THANK YOU FOR THE TIPS.

Really good as usual, This info is very very helpful. cheers mate. colin. UK.

Liked the video Adam, very nicely done. Parting is one of those jobs that most seem to struggle with from time to time. I know I do If you were trying to not get chatter it would have happened. Thanks for the great video. Steve Summers

Great video. Many greetings from Austria.

Thanks Adom, You are a excelent teacher. I love doing lathe work but always dread parting. To me it's like the game of golf some times things go wrong and I don't understand why. Mark

Just rewatched this years later. Really helped me with some basics

Thanks for the info bud.. I'm getting into machining and your video answered my question. Love your channel....!

Nicely done on the product placement. Too many times it's way too obvious and canned but that was a great use of an advertiser product. You showed it perfectly and now I gotta have one. I'm always dicking around with the center or using a scale, that height setter works sweet.

If your chuck is not true. With the setting gauge on the tool tip, rotate the chuck by hand until the bubble is between the high and low spot. This is the rotary position where the tool should be set as the rod is now on the vertical centreline. Now adjust the tool height until the bubble is on zero.

Thanks for your videos. Very helpful to us home shop guys. Fred in Pensacola

Yet another very interesting and informative video Adam. Thank you for making it look so simple, I would have got the thing chattering like a pair of old women! But doubt the tip on mine would have been set too high! Keep them coming! I would like to see a video on the various methods of knurling, if you haven't already covered it. If you have I'll look for it.

John Mills may need one of these to improve his pineapple slicing.haha. Thanks to you Adam for your very informative videos.

Excellent instructional video Adam. Please do some more, perhaps one on speeds and feeds and one on insert selection.

This was very helpful. I don't know exactly what I did, but the cutter just exploded all over. I used lots of oil, but I might have had it running to fast or too much tool pressure. I just finished it off with a band saw, and resurfaced the end. It was long enough to re chuck, or it would have just been tossed out. I still have a LOT to learn!!! Thanks for the examples.

Great video for those who arent familiar with parting and the tooling used... i wanted to mention i sometimes use carbide on plastics and softer material but ill use an old insert and grind the end sharp on my diamond wheel... it reacts similiar to hs and stays sharper longer... btw never saw that height gage... im gettibg one... thanks

As always, thanks for the humble, quality teaching. I'm using T-style parting tools on my small 9x20 lathe and I love it--so much better than the way we used to have to do, hand grinding HSS blanks. I often end up using more stick-out than you recommend simply because the small steam engine model parts I make are so close to the chuck that the tool holder would hit the chuck. Fortunately, with small parts the forces involved are much smaller.

Great video Adam!!

Hi Adam, I seem to remember all of these tips in many of your videos so it great to have them combined in one session. Also I am sure your friend Mr. Pete has mentioned on many occasions how parting off is not his favourite procedure. I have carbide with the small inserts but they tend to move with the slightest lateral pressure. I would like to acquire one of the blades with the longer insert to 'spread' the tool pressure load. Many thanks for sharing. Kindest regards. Joe.

Another great video Adam learning lots suggestion as to when to use cutting oil over flood coolant

Thanks Adam one of your best!

finally i found someone i can understand. learned alot

thank you you did answer some questions for me. as always thank you for sharing!

I get that spray on Carbide to Adam , Great info ! Going get some HHS now .. thanks man ! Thumbs up ..

walter makes INCREDIBLE parting tools.

Enjoyed it Adam!

I have an older logan lathe that has a flat belt drive that I'm purchasing tooling for. Thanks for the tip on flat belt drive lathes. Will help me in my purchase of the right tooling.

Great Video as always, Thank you Adam. BTW I just ordered the Edge Technology Tool Height Gauge.

Another super helpful video.. Thanks!!

My number one word of advice is be at or below center. I have found all the other variables are 1-2% where as tool height is easily 80% of any problems that occur. I had a job one time where I broke carbide cutting blades one after another when I finally figured out it was just .005 above centerline, lowered the tool .010 and parted 4130 for 3 whole days with one single tool bit.

Funny but these sort of expressions aren't helpful for making women feel welcome in the trade.

Adam, great stuff, thanks for sharing. I would add on for the new guys, that "rigidity is everything!!!!" I like that phrase, I stress it with my new programmers and setup guys. During chatter problems pulling that blade into the holder even .100 can change things. 10% and 20% reductions in tool hangout, chuck hangout, stubby tool holders, etc can solve headaches fast. Tool pressure is of course very important as well. Very sharp carbide inserts are available for insert tooling parting tools for materials like ALM and brass. Funny to see you take a brass shower :)

This video really helped me, thanks!

Very useful. Thanks Adam.

the HUGE thing I finally figured out, was my taper attachment allowed slop in cross slide, and THAT allowed tool to be pulled INTO cut, and bad things happened... just like slop on a milling machine when climb cutting!! fixed that, all is happy now and much less exciting!!

Nice demo, Adam.

Related, is cutting o-ring grooves and snap ring grooves. External never seemed to be too bad if the insert or HS tool was sharp, but internal grooves always seemed to chatter. A tool and die guy I worked with had a set of ball bearings on a short 90 degree holder. One set he would tap some abrasive like diamond dust from the tool grinder the other he'd just force in and trust the ball to be harder than the work piece. This was many years ago, and maybe there's some tricks on cutting these grooves you could share.

adam thank you sir for the education i have learned alot today

As usual, great job Adam. YOU are a class act! I think the guys using light lathes have problems for several reasons. First thing is worn sprung or bellmouth chuck jaws. Causes hogging in when the part wiggles and snatches the bit then binds. Stalls the machine. Check your Jaws! Another big problem is tool posts that hang way to the left side . Oh yes, it's rigid but that lefty hang torques the slide over too much. Now it's springy. Try a lantern post centered over the middle of the slide so the load goes straight down into the saddle. Not hanging off to the left field. If someone wants to say lanterns aren't rigid enough for a light lathe I have 1 word for you, Shut the heck up! I'M talking. Just do it! Works when using wide radius profile tools too. Why aren't you using power feed when parting? That's the best way! Smoooother. The bronze is chattering because of incorrect rake. My two cents ain't worth a dime. Thanks for sharing with everybody.

Thanks Adam. Very useful

Very very good information!

Timely - I spent the afternoon snapping HSS parting tips today on some 1/2 dia Stainless rods.. By the time I had the RPM about right, I had reground the tip umpteen times and switched to a narrow carbide tipped tool - the tool pressure was very high and caused other problems - so back to the HSS blade tmw and more lube & check through what you listed Adam. Thanks All the best Mat

While I have a light 13 x 40 Chinese lathe that is about 20 years old. I find the insert blades to work the best for me when going deep.. I can part 2 inch washers with 3/8 holes out if 316 stainless. I use mostly 3/32 parting tools. High speed steel tools are only 5/8 tall to fit the BXA style Aloris parting holders. I find that if I try to use high speed steel that the straight sides can grab the work and snap off the blade if not careful.. This occurs when running much deeper than the height of the blade. Shallow parting, I can use high speed steel. Steels and aluminum seem to like cutting oil. I usually cut at 1/2 the normal high speed steel RPM for the diameter. I copied you idea of the rounded parting for doing radii. Works real well as you say for making tool clearances when cutting threads and shoulders. I really enjoy seeing a journeyman machinist work. Thanks.

Good subject and info Tks Adam

Awsome job

good video and demos.

Thanks Adam!!! parting is a nightmare for me....this will help!

I cut out a block for my tool post to hold the Armstrong tools. So many HHS cut parts are now useful. I have old and new. HHS and Carbide and even Sapphire which is used in rubber and some plastic. I have Sapphire in sheet parts (shattered flats) and a round or two. Also a nice window glass.

Hi Adam. Thanks for another informative video on how to make flat washers out of brass and steel (just kidding) :) Interesting to know that one CAN use a carbide tool on softer materials; you'll just have a clean-up job, afterwards! Keep making videos; I always look forward to SNS, especially if there's some machining involved. Too bad KZread doesn't have smell-o-vision when you do your smoking/barbecuing content!

Excellent video. I think a lot of folks' biggest issues with parting is using the cheaper HSS blades that have no or little relief - or they don't have the right holder, etc.. That's where inserted tools have a big advantage, the relief is right there and easy! Surprised you don't use auto-feed, Adam. Obviously it works great for ya. I usually use autofeed on a manual lathe, most tools I have used like around .003 IPR for steels. CNC lathes you can obviously push a little harder, because you aren't having to catch the chips with your face... hahaha.

I remember setting up lantern-style cutoff blades back in highschool. I would rather unchuck, and saw cut! We only had one lathe with a quick change setup: I quickly found out to always call dibs on it. We would also grind all tools from blanks (HSS) With a week of school just dedicated to cutter geometry. It's a shame none of this is in schools anymore. I'm glad that there is some great channels on here to learn this (or, re-learn in my case) I've flung more than one insert out of the press-in type. Can be quite sketchy on an old clapped-out lathe.

Yep I think most of that is older tech to where classes don't teach it anymore. I know there are some out there because I have seen pictures of my viewers there.

Nice job Adam. I've found with the lathes I have at the shop (low powered & not very rigid) that being on center, sharp, and square all are critical. Also I think with the Aloris style blade holders they have the tool at an angle already so you don't need to grind a back rake. But yours as you pointed out need some back rake ground in.

adam very informative video.

Great video! Rule #1 that applies to new users (esp on hobby sized machines): don't feed too slowly and let the tool rub! Commit to the cut and keep it going, especially on stainless steel. Adam didn't mention it since light/hesitant cuts aren't even in his dictionary anymore, but it's probably the number one mistake new hobby users make when parting...

Good information, thank you.

Lots of great tips. I especially got a kick with your comment about chatter not occurring during the video but on actual parts you are working on. Ain't that the truth :-0

Great vid very helpful
