Adam you have so much experience you don't even think of this. Any plane milling cutter with a hole in it must be put on arbor facing the right way . If you don't the cutter will run backwards and instantly dull the cutter right out. I sharpen cutting tools for a living and I have seen it with inexperienced operators. You can tell by the direction of the burn on the cutting edge. You have worked with this type of cutter for so long you don't even think about it .
10 thousand watched, and only 1.4 thousand liked! have the courage to say that this guy records a video that is interesting not only for beginners but also for professionals!!!
Thank you very much for your detailed discussion of how you chose to make these keyways. This kind of information is extremely useful for those of us just getting into machining or getting back into the field. The Planer gauge tip was excellent.
How is it that the work you put out is worthy of hanging on a wall just to marvel at it's beauty? I work in a shop and have never seen such amazing stuff🤣. Absolutely inspirational! There's no question why Chicago put your work in a Museum 👍
My uncle use to be a machinist for a big company in Ontario Ca many years ago, he started his own small shop at some point and was doing well.....I had the opportunity to help aroumd the shop and I wish I had taken the time to learn mpre about what he was doing. Needless to say, im learning way more now through you than I would have at the time with him. My math skills has always been lack luster but you make machining much more cooler than ive seen most people do.
You could also use an adjustable parallel under the shaft and touch off on that to get the height of the bottom of the shaft to the cutter. Then move up half the shaft diameter minus half the cutter width.
Rpm will only start dropping when the maximum rated power output of the motor is exceeded. Considering this is heavily geared down it’s nowhere near maximum power. With stuff geared down like this the system has plenty of torque to break all kinds of stuff. The only time you’re gonna get close to maxing out the motor power is when running at high speed and taking a heavy cut at the same time.
Great observation though...if you can 'feel' the resistance or chatter in manual machining, where are the sensory indicators when performing CNC work--are there differences in tooling in which it just doesn't matter? Need a plunge cut in whatever go for it no chattering involved?
These comments are aimed more at newbies and hobbyists - you experienced folks can skip 'em, agree, or razz me for being too obvious/pompous! ;) Setting up your work is key to getting good results... that said, there are usually multiple ways to go about things, and multiple tools, some quite simple, that have evolved over the years. We are lucky to have so many options from indicators and digital readouts, to several more basic tools. One thing that's key is knowing what your allowable tolerances are... sometimes in a hobby situation, we'll go for a tighter than necessary tolerance for practice, but if you need a repair part by a deadline for example, you might just want to consider doing things to the "Good Enough" standard without cutting corners. Some of the older tools are bare-bones simple - a bit of wire rod ground to a point and held at a height by a couple of setscrews and rods off of a ground base - hey, you need to have something as a flat reference surface! -a good solid true square, and a level can often get the job done. Think about your geometry, and you can probably come up with two or three ways to do your setup, often with tools you've already got... although, it can be fun to buy more toys... I mean tools! ;)
Do you cut the keyholes first rough, then turn the shaft to size, and then finish the keys? This way there will be a lot of interrupted cuts. I'm just asking to learn.
@@belatoth3763 on a shaft with tight runout tolerances we rough out the diameters. 020 inches over size, then cut the key ways .010" deeper than plan dimensions. Then check the shaft for straightness, we usually have to use a press or heat to get it back within tolerance before we finish the diameters & threads
@@jimwright8379 What are the tolerances? tenths? Note that on this shaft the bearing journals are very close to the where the keyways are cut. The exception is one far out on the thin end with the long keyway and the one most prone to 'go banana shaped' but it is also unrestricted so less of a problem.
@@utidjian We are working on pump shafts for the US Navy , I can't tell you the tolerances that we are holding, however if it is running within. 005" T.I.R. for that friction press it's probably just fine.
@@jimwright8379 Ah well... yeah this is not a pump shaft. My guess is a few hundred RPM at most. Those bearings surfaces will be within 0.005" for sure. I am as curious as you exactly how much runout there is though.
It's cool how the rotation of the horizontal cutter and frame rate matchup. Reminds me of videos of cars at highway speed that look like they're not moving
The plainer gauge was an awesome tip to keep around. Last time I had this problem I touched the cutter off on the base of the vise before loading the part then worked from the bottom of the shaft up. Thanks for sharing
I wondered why Adam didn't just set the planer gauge under the shaft to reference the bottom and then come up from there obviating the need to use an indicator.
If you touched off with the quill on an upper tangent of the shaft and then again off a lower tangent and split the difference, assuming you used the same Y location, would that also work?
silly point Adam....as a cameraman. if you had a pro camera with variable shutter speed, it would stop the strobe/ reverse direction of rotating tools. maybe worth investing in?
Adam I found you from Mr Pete , please help him with his channel, I consider him a National treasure such a nice older gentleman and you sir are brilliant and what a treat and great experience learning from you as well
man I wish I had the skills you do my father who has passed a long time ago probably did way back in the day but he passed before he could pass on his knowledge to me I can do metal work but I am nowhere near a machinist but I do understand keep up the good work man and loving your new shop
A note to Andrew, the owner of this shaft... The proper fit for keys is a light press fit into the shaft and a clearance fit in the female bores of whatever attaches to the shaft. It is improper per established engineering standards to have slip fit keys in a shaft. Movement will result and the keyseat will fail from plastic deformation. These are not my standards. Look in the Machinery Handbook for the fits that I am talking about. If you have ground down, test fit keys, don't use them. Use new properly fitting keys. ---Doozer
Shaper gauge could go, without any indicator, under the shaft and under the cutter. Would need to compensate for backlash whilst cranking down the knee tho. Else: that wobbly black rim/taper on the toolholder would drive me nuts.
Nice job AB! Adam you should check out IC weld he loves your channel. Unbelievable weld job last episode. Squared up! Machined with what he had said you'd be proud of him 4 sure on his machining job 2 episodes ago. 2 👍👍Good reach out. Needs how to tips and tricks on best 3 piece insert and holders basic everyday machining. Gettin it done. 😃👍
When you flipped your bar around, Adam, I wonder if you readjusted your end vice's solid jaw alignment location to compensate for the difference in diameter? It almost looked like when you cramped the end of the shaft..... It bended. (Maybe just an optical illusion)
Hi Adam I hope you are having a great time at your new shop I have a question for you please what size milling table and the size of the Kurt vice you have there all the best from AUSTRALIA 🇦🇺 Hoo Roo Paul 🍺👍
I gotta say, I never had any previous interest in this stuff but I find myself captivated by your videos. How you measure everything exactly and how you get it so accurate is a real art.
Yeah, same here. I'm in IT so I have absolutely nothing to do with machining, but his videos have awakened a certain fascination for the craft in me. Might have to get myself some machines at some point (maybe a CNC, combination of IT and machining)
I would have set the planer gauge under the shaft, and thus used the bottom of the shaft as the reference height to set the bottom of the cutter. I would then raise the cutter (lower the knee) by shaft radius-half cutter width. This avoids having to fool around with the indicator.
Its Its funny but i made a planner gauge when i was an apprentice the tradesman always used a cigarette paper stuck to shaft to tell when the tool was .0005" to get the centre of the shaft he would scribe a line with the lathectool point when the shaft was in the lathe so he could move it in the milling machine and line the keys up Well done mate
Do you still do work for the public I am local to you and have a small spine shaft I'd like to have made would you consider doing it for me I can't seem to find your business phone number or I would have called
Hi, JUst wondering why you didn't just use the indicator to sweep across to the top of the cutter and calulate your Z from there instead of using the planer guage?
So when cutting long key ways like the last cutting in this video... it's better to not climb cut r did abom... Under cut it because it was just easier and it really doesn't matter...
Nice tip on the planer gauge. I’ve seen those pop up now and again in my fb market groups and wasn’t super clear on how they were used. I love the “old” ways.
what's it mean to be on the flat when establishing the zero? wouldn't the depth be measured from the side dead center (if that's a thing)? do you need to bring it in until the entire height of the tool is cutting before establishing a zero?
@4:47 - I use this method to set the tram and level of my 3D printer beds. Regular sheet of paper and close the gap till it drags. It's worked going on 3 years for 2 printers now.
Very cool to see a project come out of the new shop! Do you know why he didn't use a press to straighten the shaft? You wouldn't have had this awesome series if he had chosen that route.
Being a welder/fabricator that is trying to venture more into machining, it was cool to see the planer and shaper gauge trick. Gonna have to use that one at work.
Stronger as a woodruff keyseat is machined deeper into the shaft than a square key. BUT when things bind up, they can tear the shaft up more. Many metric designs use rectangular parallel keys instead of the square keys that American designs favor. --Doozer
Really cool tip on using the planer gauge , thanks. You mentioned there are several other "tricks of the trade" with planer gauges, would love to see a video on those. REALLY like this video, well done.
The feed rate and shutter speed really make a very cool looking video. You are the man Adam. Work is outstanding ,and your video's are just as impressive. Thanks for always sharing.
A rather expensive part after being machined no doubt. Likely its more precise than the original which Andrew will surely find out as he installs it into the machine. Nice work Adam
Beautiful work as usual. My Dad this stuff all his working life. Finding his tool chest with it's sine bars in and calculation records was a bit of a thrill.
Gotta watch more period dramas, friend! Same thing happens when you see an Amish-style vehicle on camera. The wheels sometimes look like they’re rotating backwards. (My mom loved watching PBS back in my youth…)
This is not strictly only a camera problem. If you have lights in the shop that are flickering in synchronicity with the rotational speed, you may get the impression that a machine isn't moving or moving slowly. This can even be a real workplace hazard if the machinist gets confused by it.
@@Gameboygenius Wowza I didn’t even think of the safety concerns!! But what your comment makes perfect sense to me now that I think about it! (I guess I’m fortunate that PWM vs. Shutter Angle is only an artistic concern in my trade…)
Adam: the cinematography.. watching that key cutter at 60RPM at 60 FPS... art man. that was art. It worked...
❤

That planer gauge is one beautiful tool. I don’t need a planer gauge but now I want one bad.
VERY Nice job! Thanks, Adam
Excellent job. Planer gauge awesome tip. Skilled Craftsman at work. There is Adam and Curtis at CCE.
I smell a CNC video coming. Someone is getting the lathe ready ;)
You need to get with Brandon Herrera he needs a machinist that's willing to do custom work
Well done, Adam.
Uy! at 16:39, the cutter is loose on the arbor. :) Very nice job, "as is tradition".
Beautiful work.Thank you.
Beautiful part with lots of features in it! Beats that old beat-up original LOL. Appreciated this set of videos Adam!
That table looks familiar.
I’m Sure we gonna see some cnc action soon. Looks like we have some leveling going on and set up
yes i sore that as well
Check him out on his facebook page. CNC going on there!
I saw Mr. 'I'm not here guy" too! LOL!! I was like... Who the hell is that?? LOL!! We get so possessive on the yoobtube!! LOL!
I thought about that too. I thought I saw the previous machine that was on that corner however.
29:28 Machine Gremlin behind you.👀
You should be teaching at a trade school. You make everything understandable
Thanks for sharing 👍
Thats why I am a big fan of Abom. The cnc machine's have there place. Just not sure if they are Adam's cup a tea .
We shall find out soon.
What’s really impressive is that the RPM didn’t vary by more than +/- .5 or so when loaded down by cutting. That’s one, sweet milling machine. 😌
The rigidity isn't super good though. Imo they should've made it with a 5" or so thick quill so they could fit a proper thick 40 taper shaft in there.
Rpm will only start dropping when the maximum rated power output of the motor is exceeded. Considering this is heavily geared down it’s nowhere near maximum power. With stuff geared down like this the system has plenty of torque to break all kinds of stuff.

Gotta ask you got someone trouble shooting the Cnc lathes or a new apprentice honestly would love to see ya pick up one
Aww man that machine needs a Z for that newall!
Is that shaft still straight after you cut the key ways in it? We usually pre-machine key ways on long shafts where I work.

I would have set the planer gauge under the shaft, and thus used the bottom of the shaft as the reference height to set the bottom of the cutter. I would then raise the cutter (lower the knee) by shaft radius-half cutter width.
This avoids having to fool around with the indicator.

Hi, from Sydney Australia.
Brilliant! Adam, take a minute on one of these to show what you use to clean the swarf out of your machines.
What would be a ballpark cost of machining that shaft?
Very cool to see a project come out of the new shop! Do you know why he didn't use a press to straighten the shaft? You wouldn't have had this awesome series if he had chosen that route.
