SNS 244: Electric Motor Shaft Finished

[@BernardSandler]

Hi Adam, I just wanted to put in a random note. I've been watching you awhile now. Lately more than usual. Going back through the archives through SNS and various shop projects. Life provides some dark moments and in those moments we seek out islands of sanity, sturdy rocks to lean on. Your dedication to work, to excellence, to precision and perfection has been of more comfort than you know. You reaffirm that there remain people out there who care about what they do, about getting it right and about being teachers and sharing their knowledge. The affection you have for the tools and skills imparted by your father and grandfather are obvious and admirable. You keep being you. Thank you.

[@Abom79]

Thank you!

[@moeszyslack4676]

Well said. I also appreciate that Adam doesn't curse constantly. Not that I'm a prude, I do it myself more than I should, but it's nice to get a break from it.

[@lukasdon0007]

Hey Adam. You and some other youtubers really inspired me to get a small lathe and start making stuff. I've been having lots of fun turning some small things, and it's very rewarding becoming better and better every time I make something. This week I needed to turn some simple stepped bushings for some project; 6mm ID and 9.12mm on one side, 12.57mm on the other side. It was the first time I really felt comfortable hitting it exactly on spec without really breaking a sweat. The odd-ball sizes were annoying, but they didn't intimidate me as much as they would have a few months ago. When I hit the 9.12 I was so happy and proud. I know it's just a simple thing, but it was a nice moment for me. Your videos have really been a huge help and inspiration to me.

[@--Zook--]

I cant wait to build a shop so I have room for a small lathe. Adam and all the other usual suspects have inspired me as well.

NACA Lewis is actually NACA Lewis Flight Propulsion Laboratory, now known as NASA's Glenn Research Center!!! HOLY CRAP!!!!! That book is a part of history!! NACA Lewis is where all the research for liquid hydrogen use as a rocket fuel was developed and most current liquid propellant rocket engine technologies used by the US were developed! :-O!!!!!! The tie in to Notre Dame is very very historical. University of Notre Dame was one of the universities that was doing heavy research in the areas of propulsions and aerodynamics for inter- and exoatmospheric flight for NACA and the government. Its probable that a worker/researcher/professor/student was at Notre Dame and then transitioned over to Lewis/Glenn in Cincinnati. The ERB (Engine Research Building) was literally the heart of all research at Glenn. Rooms of draftsmen and engineers designing and producing drawings to be built in the machine shops to ultimately be tested and/or flown. Whoever owned that book was likely a machinist or engineer for NACA Glenn at one point. WOW!

[@Abom79]

Thanks Brian! You're a book of knowledge yourself!

NACA was the predecessor of NASA. Lewis Research Center, now Glenn Research Center, is next to Cleveland Hopkins airport. ERB would be the Engine Research Building, 263 would be his mail stop.

To get keyway depth use say a 1-2 micrometer and measure from bottom of keyway to the other side of shaft, take this dimension away from shaft diameter. Just a thought from England. Great videos Adam.

Hi Adam, you are looking great. This is building up to a really great series of videos. It was so nice to see Stella's picture in the background at the end. I'm sure I can still see her some nights in your shop (like Bailly in Brian's shop) checking up on the progress of your projects. Most sincerely. Joe.

Manual machinists are a dying breed and just when I think to myself Id take .005 to see where its at....thats exactly what you do. I machine pump parts and safety valves for the past 13yrs with a total of 17yrs machining experience. Great videos in my opinion brother!

[@profpep]

I can tell you are a true precision engineer - "About 39.6mm". If that motor rotor has some dings in it, it might be worth seeing if the motor guys can do a dynamic balance on it, considering the quakity of the shaft you made. As always, thanks for sharing - I learn something every time I watch one of your videos.

[@richardfrisbie6069]

Another great video series Adam. I always appreciate the repair rather than replace content, but then that's what makes you a great machinist.

[@Abom79]

Thanks Richard. I guess the guys asking why I didn't buy a new motor don't want to see the repair content.

[@cryptic22]

Excellent precise job again. Looking well with the weight loss. Keep them coming. Dave UK.

[@agentbertram4769]

Adam, don't forget that the rotor laminations are dipped in varnish so that they are electrically insulated from each other. This is to reduce eddy currents and power loss. Make sure that the cleaning job does not allow them to short out. This will reduce efficiency. Great job and most interesting. I really enjoyed these videos.

[@argee55]

"NACA Lewis" is shorthand for The National Advisory Committee on Aeronautics, Lewis Flight Propulsion Laboratory. It is located in Cleaveland, OH and is now called the NASA Glenn Research Center, renamed for the NASA and John Glenn. (NASA - National Aeronautics and Space Administration, succeeded NACA as we entered the space age.) Thought you might be interested in a little history. You seem to like museums.

And there are things that you can buy, but are better made from scratch and give a great satisfaction when they turn out better than what they are trying to get you to pay retail for. And there is many inferior Knock-off's that mimic things from a better time period, I could go on and on about these things.

[@OperaBass3]

Run-out is way better than I feared. My motor shop experience was 35 years ago so maybe my recollection is a bit cloudy. I recall pressing a finish shaft in an armature worked about 4 out of 5 times. 1 in 5 required a little inspired press work to get the pulley end of the shaft in line with the bearing fits. Nice work. Economically done. Motor shaft replacement is a good test for a new on the job machinist. Pass that and you're on the way to continued employment. Fail and you're out the door soon as the next guy passes his interview.

[@Abom79]

It is enjoyable to see the results of the shaft replacement, looking forward to the completed motor restoration! What if anything else will you be doing to restore the remainder of the K&T? Your efforts to maintain and improve your machines and tools yourself show your passion for machining more clearly than any number of jobs by or for others.

Good job, on larger rotors you can finish turn the shaft first, but on smaller dia. Rotors they can bend / bulge at the ends , that’s why I always rough turn the shaft then press in then finish turn , that way all areas run true.

[@SynchroScore]

My first machining job was in an electric motor shop, though they used a different process to replace shafts. First, one end of the shaft was sawed off, and the rotor set in a lathe, so a drill could be run through it. The idea was not to machine the shaft entirely out, but to take most of the metal out of the middle, so that the rest could be pressed out easier. The rotors at this shop were a fair bit bigger than this one, and would've taken too much pressure. To put them back in, the rotor was heated with a propane torch until an infra-red thermometer read 400° in the rotor bore, then the new shaft inserted. Usually it dropped right into place, but sometimes needed a bit of pressure to seat it. The shafts were also made with a shoulder that fit up against the lamination stack, to make sure the axial position was correct. Also, at the end, that motor might have even less runout than you think. Remember, in when assembled, it's turning on the bearings, not on the centers. So if you set it on balancing rollers, running on the bearing journals, then you'll see the runout as finally assembled; if the rotor stack and the drive-end bearing journal had the runout with the high spot in the same place, it'd be nearly perfect. Either way, that's more than good enough for this machine, with any wobble taken up by the drive belt.

Hi Adam, thanks for the video as always. Regarding the Machinery's Handbook, NACA - Lewis (Flight Propulsion Laboratory) is the predecessor of NASA/Lewis - Glenn Research Center in Cleveland, Ohio. NACA, short for National Advisory Committee for Aeronautics was established around WWI to oversee Federal government funding of research into human flight, changing to NASA in 1958. It seems possible Mr. Steinflug (sp?) may have been involved in machining work at the Cleveland research location prior to 1958, suggesting he may have been involved in research projects providing the foundation for rocket engine design used in project Apollo. This book may have quite a history associated with it!
