That's pretty much what you'd call a Belleville washer. The biggest I've ever seen. I learn something from every video you post. Thanks!

Da man shows us how to complete a challenging item on the lathe with ease. Thanks Adam

I'm a new viewer from the UK , I have zero experience of the stuff this guy does but I love watching him work.... superb work

I love watching these. I built most of my furniture; fine woodworking. And for years I was a synthetic organic chemist, which means I dissolved two distinct chemicals in one pot, boiled them overnight, and they reacted to create one new chemical. All of these have in common the sense of "a job well done." That wonderful satisfaction you get when looking at something you have made.

Hi Adam, I have watched everyone of your videos, I love them all mainly because of your personality and the quality of your work. This one and the previous video you posted have been your best. Your non stop talking detailing how and why you are doing what your doing is like I am standing there asking you questions and you're there answering them. Keep up the great quality that you have been giving us, thanks.

It's an optical illusion. The new part looks a lot bigger on video. Nice work again Adam. I hope you have lots of videos because I'm learning a lot by being a fly on the wall.

I really enjoy your videos (metric guy here), As an mechanical engineer, I design complex precision parts all the time. I would never ever being able to make those parts if it weren't for the machinists in our work shop, I would have been lost at day one when I started working. I have the utmost respect for you and other machinists out there.

Wow, never realised a reamer could take off half a mill. Cool video. I'm just learning to lathe as well, this is really helpful

very nice job on that tapered washer! I probably would have made it way to complicated. Great to see how a master got it done!

the speed in which you zero your 4 jaw is mind boggling, another cool video, I should have apprenticed with this guy

Wow watching you center that chuck is impressive

Really enjoy your shop video's. You, Mr.Pete and others have renewed my interest in metal working.

Hey Adam It is good to know that others get a noise when parting. I have a Taiwan made 12" which some times seems to be posed with evil stuff. The only way I have found to deal with it is slow speed and lots of oil. Still a scary operation! Really enjoy you calm approach to things.

It's always interesting to see how you approach making a part. This one, while appearing simple, was very educational. Thanks for sharing.

I like the metric stuff. Kind regards from Germany 😀

Very interesting. It is exactly what I wanted to make washers for my grinders. I had two other small lathes biggest being a 10x24 and cutoff work was never very successful. When I got my 12x36 lathe with the 200 series toolholders all the videos showing it done with such ease became real. It is rewarding to have fought it all these years and now having it so smooth! Keep up the great videos.

Well, that was different...but that's when I learn a lot. Thanks, Adam. I used to work in a shop that built all its new stuff in metric. It is easy to use if you don't have to switch back and forth between one system and the other--that's where it gets hard. Nice video, Adam, easy to watch. Joe

+1 for saying "this little Victor..." with a straight face :)Would have been a tough part even with HSS, great job with that fat carbide insert.

I never thought of using some rod in the tailstock to catch a part after parting it off, I did it today after watching this vid and felt like a pro. Thank you.

I had no idea how to make that piece. You make it look easy as usual. Great video Adam. Thanks

Now i know how Conical washers are made on the Lathe, awesome stuff.

every day watching you dial in the 4 jaw just amazes me . You are so fast at it

thanks for showin us how that process works. don't think I've ever seen an angled washer plate like that before but now I've got the gist if one ever comes my way. great video as always

Nice video and nice work .. I do like your videos a lot. You don't "over explain" like in many of the other channels. Greatly appreciated.

Great video Adam. For information we would call that design a Belleville washer but it would normally be made of spring steel so that it can flex when put under pressure. Most interesting to watch the process of how you produced a copy of the original, without the wear of course! This mess of metric and imperial measurements on components is a pain but is far worse with the various threads in use here in the UK.

Hooray for millimeters.

I was one of the 'cross over' kids here in Canada. Started school in imperial, graduated with metric. oh my friggin gawd. what a mess! And we still had to learn to covert Imperial (English) to U.S. volume capacities! Good grief. (i.e. 1 U.S. Gallon = 3.78541 liters compared to 4.54609 liters per Imperial Gallon). And this conflict started all because of global trade protectionism. Nuts I tell ya! It's the same with DVD country codes, telephone systems, power systems. There are huge advantages to metric as a measuring system - because it is decimal formatted without any conversion required. Every car manufacturer in the world now uses metric across all brands and regions - including the U.S. About the only holdout left is the U.S. military industrial complex in some very specialized segments. One day there will be only ONE global measuring system. Not in my lifetime though.

I'm not positive but I think those are called a compression washer. They hold more pressure on the nut than a plain flat washer. Great video. I have been watching a lot of your videos the past few days. Keep them coming. Very interesting.

fun to watch, for the first time I tried putting my HSS parting t shaped bar in my small 11"" Rockwell lathe upside down and ran the lathe in reverse and the put an end to the vibration so that was helpful for me. so this done on another video. Nice work you folks have more patience than I do, but am improving with all your videos

watching this while machining a sprocket for my motorized beer crate. had to make a new rear axle because a friends vehicle lost one wheel and my old axle is made the same way.

Millimeters, oh yesssss!!! Although I almost understand Imperial after watching your videos, Adam.

Wow,This guy can zero in a 4 jaw fast!!! Great video.

So a belleville washer. Neat!

Some sweet machining there! Always a pleasure watching skill at work. I do miss it since retirement, just not the pushing foreman hollering, "More feed! More speed!" lol

Another great Sunday morning! Thanks!

Sure wish I had that quality of scrap material available!

Good Job Adam! That was a lot of metal to remove for a small part. Thanks, CJ

Very interesting and very timely. I have to cut three parts similar to this. Thanks, Adam. And well done. Norm

Adam, love the videos! Thanks for sharing another one with us. :D

Another fine job, and an interesting approach to the problem.

Furthering this metric/imperial argument... every commodity product you buy in the U.S. has the metric weight or volume printed on the label, right underneath the imperial units (it may be a law, but IDK for sure). However, few products come in "even" metric units, except some beverages (1 liter, 2 liter Coke/Pepsi). Almost everything is an even imperial unit (a pound of cheese, a gallon of milk). My thought has always been that even metric units of weight and volume are slightly larger than the imperial unit (a liter is bigger than a quart, a half-kilo heavier than a pound) and making larger volumes would increase the selling price. No company wants to be the first one on the shelf priced at $1.05 instead of $0.99. Those who look solely at the price will buy the "other guy's" product. So we plod along in Imperial, and as Adam stated, we are used to it. The simplicity of dividing metric units is attractive, but most of the time we convert fractional inch units into thousandths so we know how much to cut anyway.

Nice work Adam. You make some of the best videos on machining on You Tube!

Great video Adam - thanks

That was far from easy! One heck of a reach for that parting blade. Great doing it all in one position - nice job Adam.

Nice video Adam, learned a couple of things on this one Thanks, Craig

You made a tricky job look easy.

Nice work Adam! Funny, that indicator o.d. match stock piece. Sweet :))

I guess it must be an optical illusion at the end when the old washer appears to have a bigger bore than the new one. Really enjoyed seeing your parting tool take that side load Adam, guess its a sandvik blade, my no name blade bends like a banana with part tip load.

Awesome stuff Adam. Thank you for sharing!

Nice job Adam, Thank you!

I am a machinist and a CNC programmer in a hydraulic cylinder manufacturing business for 12 years and we deal with 80% imperial and 20% metric. All our CNC lathes are in imperial, it's a pain in the ass sometimes but I wish it was just metric. Because being taught mainly metric growing up here in Australia. lol.

great job Adam.

Heh heh, got to see one of the things the Victor lathe just doesn't enjoy doing at all, in parting with carbide insert tools. I'm guessing the main reason is just because it ain't got the girth and bulk the big Monarch has that makes the Monarch just so much more rock-solid, so the Victor can't take the tool pressures from parting with carbide inserts. Impeccable skill again Adam. Looked a little hairy working that close to the chuck, especially the facing/tapering on the outside of it where you could have it in high gear and the chuck a blur in its spinning. :-)

just finished SnS, and boom, more abom. Its gonna be a good day

Great videos Adam. Thanks.

Nice job as always.

I think you need a Donaldson fume extractor to get rid of all that smoke. ;-) Nice video, great editing.

Adam, that was true genius! I thoroughly enjoyed that video. :)

That mix of metric and imprial is just like working here in the UK

Learned something again from you! Thanks Adam!

Adam, Nice job of turning the angle on this washer very interesting. Thanks, Jeff

Best Chanel on youtube!👍

Adam, I love your videos and have learned so many little tips and tricks from you. I love watching all of you guys like Keith Fenner, Tom Lipton, Keith Rucker. I would like to know where to obtain a tool post holder like you have on both lathes. I have found on MSC where you can buy the tool holder, but not the tool post itself.

That was some fast as hell indicatin'

Amazing how quickly you true that material up in the 4 jaw.

hi Adam, I'm not a machinist but I watch your videos every week. I was expecting you to get some deflection sideways on that parting tool away from the face when cutting the convex side of the washer, especially with the long extension on the tool.

Hi Adam, when I have loooong reach with a parting blade, I start with a much shorter reach and when it gets deeper than the reach, then I stretch the blade, makes it easier on the lateral forces to get it started... ;) 1045 works nicely... Pierre

That was good work man ! Thumbs up Adam ..

Nice videos this weekend as always. I'm still watching and enjoying although not commenting as much. I just got back from the States and Enco and MSC love me! ! Then $1,800+ in shipping from the States to here in Greenland and I'm anxiously awaiting for the last 3 (of 11) boxes of goodies. You guys in the States have it VERY easy. Acquiring tools and supplies is a breeze there. Anyway, thanks for sharing and congratulations on the K&T. Good series. $100 for a granite plate that size?! Should be a crime! hehe

Excelent job, Adam! the best of the best!

Adam, I think your Victor needs some readjustment on the main bearings. I experienced the same on my Dutch lathe.. Tightened them up and lost the problem! Keep up the good work and thank you! Best regards, Job

en hora buena un trabajo fantastico, un cordial saludo,amigo.

Nice build!....good lessons

good job adam.

good work

I am surprised it wasn't spring steel. I don't think I have ever seen an aluminum cup washer before.

you are a master very impressed

1/8 is 3.2 mm, a common drill size because pop rivets are inch sizes

24 min nice job.

Thanksfor another great Video...!.....20mm shaft is common for European stuff like 'cold saws'.... Finish on 'chrome' shaft?...I have been in a couple shops that made chrome shaft...they plate it first...that comes out very rough, (looks like it's glass-beaded) then they take off 1-2 thou with a big wide belt sander...but call it grinding...the roundness is not that critical as the rod goes through oil/hydraulic seals....they leave a slight amount of grinding lines/finish to retain an oil film.

That truing of the four jaw is just magic. If you had cut the two angles together, you could have saved yourself a compound set up step. Was it potential deflection of the part that made you take a different path?

I would like to see what kind of close ratio rack & pinion you could turn out for my Go-Kart. I know they sell them, But I'm different in my designing and building style, I have to be different and not follow the crowd, I feel most of us are the same about our special projects.

hey Adam i realy like your channel. my name is Tomek im from Poland. here ewerything is metric i was always courios how yuo can easly do calculations like 3/4 inch minus 7/64 thats difficult to me. nothing like 120 mm minus 1,7 mm is equal to 118,3 you are a great maschiner mean keep up a good work

very nice, but I saw his neck slightly lighter machine so as to cut vibration at high speeds.

You are amazing !!!!!!!!!!!!!

Hi Adam, excellent video as always, but again a question if I may. I've personally not tried it yet, but I have seen a number of YT videos on the 'spinning' process and I can't help thinking that this part could have been made easier, and from sheet material by spinning. It would be great if you would consider making the part again by the spinning process and showing us all that perhaps it CAN be done on a non purpose built lathe. Your machines are pretty large compared to most of us ( apart from Tom's, both Keith's James etc.), so I would think they could handle the forces involved. I timed your 4 jaw indicating on this project and this time you got it down to ~41 seconds. Couldn't see how accurate it was, but you were obviously happy with it and I think later you mentioned it was within 1/2 thou. So, you are the king again (re' my comment to Doubleboost the other day) - fantastic stuff. Regards Mark in the UK

rất đẹp.tôi thấy cổ máy của a hơi nhẹ nên khi anh cắt đứt mới bị gằn

Mind blowing machine work as always Adam! Have you ever tried using two chuck keys while indicating the four jaw? Mr. Pete says that's the best way to go, makes it a lot easier.

It’s recessed

Good!

Bravo !!!

+abom79 that was awesome. This is the type of thing I find really cool to watch.

That's a lot of work, for a precision Giant fender-washer !! Is the use of that lathe with a parting tool causing some weird harmonics ??

Would you attempt to cut-off to a depth like that with a non-insert cut-off tool? If so, what would you do differently? BTW, my wife got me a couple Abom79 T-shirts for my birthday----they look really cool.

Heya Adam. Nice job as always. You said that the Victor doesn't like carbide..... Too light of a machine...? What are your normal parting speeds both carbide and HSS depending on lathe size? You mentioned friction turning. Have you done a video on that type technical operation? If so I'll have to look for it. I've got a thin 2.25 dia part that needs to be faced to thickness after drilling screw holes with the mill then parting on the lathe. Any good techniques out there to look at if you haven't done one on it? Thanks

I need to machine 1/16 inch 420 SS washers from 6" diameter stock. The stock is 9/16" thick. I'm struggling to cut precisely 1/16 slices. I would use a drycut or cold saw, but it cannot handle the diameter. Would love to hear any ideas. I'm doing this to make tesla turbine blades.

Curious about your can of oil for your brush, shop made can? Awesome videos man.

110mm OD and 20mm ID, are those the final dimensions? I'm wondering if you use standardized tolerances, or just turn the exact dimensions you get.

Just curious what would be the charge for something like this to be manufactured?

Can someone explain why he used a 4-jaw instead of a self-centering 3-jaw?
