Made a thin bushing

Coworker asked me if I wanted a challenge yesterday. He need a thin seal install bushing made to install a $200 seal without cutting it on sharp edge of a hydraulic motor shaft. I turn out a piece of alum round for him. It was only about .030” thick in the big part tapering to nothing for the seal to start, and where it went over the shoulder, was only .010” thick. He and the boss was impressed. Probably will be making more of these in the future for different applications. When I parted it off, it created a slightly rolled edge that keeps it snug on the shaft, so it should work good.Attachment 148498Attachment 148497

Nice job! I had to do the same thing when I put my Rivett lathe back together.

A lathe is a wonderful tool isn't it?

Back in the day I asked Dad what machine tool to start with. He didn't hesitate a lick. "Start with a Lathe" It can build every other tool in the shop was his reply :)

Had another small part challenge. When boss asked the other machinist and I about it, the other guy said give it to me since I like making small parts.[emoji4]

The one on the right was the original, my copy is the left one.

Today’s small part challenge, a detent pin for some old hydraulic valve that parts are not available anymore. Customer thinks he broke the threaded end off when he tore the valve apart, and we think he lost a washer in the process too. I had the welder tig a bit on the broken thread to get it out of the spool, and then the customer thought he had found a spare parts online somewhere and spent $400, only to find out it was not the right parts. So I got the go ahead to make this little part. Had to order in some 4140 because it has to be sent out to be heat treated. Turned out pretty nice, I think.

Couldn't you heat treat it in your shop?

I could, but lack the proper equipment to make sure the temps are right, and to verify how hard the original is. My shop likes to make sure all our i’s are dotted and t’s crossed right when we ship something out to a customer so we can guarantee it to work. We will farm something out to make sure it is correct.
