How to Fit a Shaft for a Kinetic Sculpture - Kevin Caron
Вставка

- From www.kevincaron.com - Artist Kevin Caron needs to adjust a shaft so a sculpture he is working on will spin ....
Kevin Caron is looking at a piece of stainless steel pipe and a stainless steel shaft. He has 2 washers welded onto to the shaft.
He needs to get a thrust bearing to fit on the shaft so the sculpture will spin. The first race and the bearing itself will fit. The final race, though, is a little too small, so Kevin Caron is going to use his lathe to turn the shaft down a few thousands. He'll also clean up his weld and some other areas.
Kevin Caron secures the pipe in the lathe and applies a little cutting fluid before he uses the lathe to clean up the weld so the race fits on nicely.
Then he puts the shaft into the lathe, applies a little cutting fluid, and turns on the lathe's autofeed. About 7 minutes later, he checks, and the shaft is still a little too big.
Instead of cutting the whole length, Kevin Caron just makes a shallow cut on the end of the shaft, and checks the fit. That works, so he runs his tool in until it touches the metal, then turns the dial indicator to "0." Now he backs off the cutting tool, then starts again at the top of the shaft.
When he's done, the race fits just right, and the thrust bearing fits together perfectly. He puts the shaft into the pipe, and his sculpture will now be able to rotate easily.
This bearing mechanism is just like the one the solid section of the sculpture rotates on - now the innermost section and the solid section can spin independently.
That's just another step in creating a kinetic sculpture.
Kevin Caron is ready to go back to work, so you have time to visit www.kevincaron.com to see more how-to videos and check out his Works in Progress to see what he's working on now.
Well, you might want to stick around for another moment to see Kevin Caron get distracted ....

Whenever I have a sculpture fabrication issue I start with you Kevin. Thanks so much. I always learn something and you don't talk down at all.
Glad to help! Thank you for watching and posting.
Nice tip Kevin as always - multi-independent-spinners looks interesting but also challenging - good luck with the build and I look forward to seeing the finished sculpture; Booyah!
Wow kinetic sculpture, lathe. You're always doing need stuff. Explaining, and showing details so well. Thanks
Maybe some day down the road
That would be cool!
Thank you and all those involved in the content, contributions, efforts and production of this channel.
Merry Christmas, Happy Holidays and Happy New Year to all.
May the new year bring you, your families and friends much health, wealth, happiness, safety, security, appreciation, respect and peace.
I really enjoy that you use the kinetics and Mobius strips often. Bringing life to any inanimate object is creation at it's best.
Thanks, they are fun to make as well.
Thanks Kevin. Good info as always. That's a terrific sculpture!!
Glad you enjoyed it! Thank you for watching and posting.
thank you
A+. more on kinetic designs, yours are super.
Starting one after the first of the year that will be 12 feet tall and about 5 feet in diameter!
That is pretty cool. I'm planning on making something rather large and want it to spin. I've been welding larger and larger pieces with my Everlast and its been getting harder to get them to spin freely.
Well there you go! Lets get to work!
Great video Kevin! @desertwoodworking. Lake Havasu.
Möbius strips make interesting conversation pieces.
Yes they are.
Thanks for watching.
Are you using stainless steel for the shafts? Are you opposed to mild steel for kinetic sculptures?
Hi Kevin sir, do you know what kind of bearing Anthony Howe art use in their kinetic sculptures..
That is one thing I am really interested to learn! Love his work but how the heck does it make it spin like that?!?
Kevin, do you have any suggestions for hanging a heavy project on a wall? In this case I’m making a piece of 2’x3’ wall art out of 1/8th in flat bar and sheet... going to be pretty heavy but I’d like the recipient to be able to hang it on the wall. Should I just tack pieces of angle iron with holes drilled in them to the back, or would something like a metal equivalent of a French cleat be better? I learn so much from your videos, please keep them coming!
I have had a lot of luck with the french cleat. You can weld tabs at 16 and 24 inch for screws but you don't "know" where the studs are in their wall so hard to line up.
Kevin Caron, Artist Thanks Kevin! Have you ever done a vide of a metal French cleat? Just trying to figure out how to approach that... Thanks again for the help, very appreciated!
Not yet but a great idea!
Chuck up the washer that doesn’t fit and sand or bore out, that way they all fit nicely, if you turn shaft one washer and one bearing will be loose. ( smile )
Yes ,true
Sounded like you were getting a little bit of vibration when cutting the end of the shaft furthermost away from the chuck. If you have a center it's worth using it when there is a lot of overhang for the diameter. And as others have said, if it's only one side of the bearing I would probably just attack it with a die grinder. Good video.
Yeah, had a little chatter but it didn't hurt anything. The nice thing is it won't be spinning at 50mph. And yeah, I should of just used the die grinder on the race instead. But that would be a boring video for sure!
But will it Blend?
A nice bearing can be made from a used, usually free from any mechanic , worn out tension pulley from a timing belt. They are very plentiful and work well
Good tip!
I assume you mean a serpentine belt pulley? I have two of them which will someday be spinning around in the yard.
@@LarryCook1960 they do work well as wheels also.
@@LarryCook1960 yes it is a tension pulley for a timing belt
wrong kind of bearing really. forces are in the wrong direction , dont mix up standard spherical bearings and thrust bearings , 90 degrees off .
Kevin, can you provide a link where you get that type of thrust bearing? I'd really appreciate it.
This is where I go but there are lots of other places as well. www.vxb.com/Thrust-Bearing-Online-s/209.htm
@@KevincaronSculpture Thank you!
Did you consider making the bearing's hole bigger with a die grinder? Considerably less work than shaving the entire shaft on the lathe, I would think.
Bahahahaaha. No he didn't.
artist , not engineer ,, two totally different breeds.
Super Anleitung
Lathe shaking at 2:00 is scary 😮
Thanks guy! A very "moving" message this time. (I know, I know...)
Groan!! You are such a kidder! Happy holidays to you and yours!
On the bearing race why not just open the race to match the other two.
I'm sorry but I don't understand what you are asking.
wouldn't it have been easier to just drill it the same size as the bearing ?
Thrust bearing washers are very hard
What Eric said!
understood, thanks
Kevin: how did Alex Calder get movement in this large stationary sculptures?
Which sculptures are we talking about?

see the black base pivot point, not the outrigger mobile arms.
Probably a point inside a pipe with a little grease. Or a collar bearing inside the larger section of the pipe. Can't see the joint clear enough to tell for sure.
Very un-safe to machine the shaft without using the tail stock. Way too much overhang. You were very lucky that the shaft didn't just pop out of the chuck and damage the job or yourself. I know from experience how this can happen.
Just need a better rest than what i have. doesn't work well and don't need it that often. But yes, i know that was bone head and I am lucky!
