TomI made a thing.
It's a needle bar piston joint for a Singer 29-4 patcher sewing machine. The old one was worn and abused, not sure if an owner along the way ground the tip down or the factory did because the bottom of the hole wasn't as big or the hole had a bushing put in the bottom.
I drilled out the hole in the drive arm, turned a new piece on the lathe to match the hole, then shaped the rest of it mostly by hand and drill press.
