You can also tap the end of the hex shaft and sandwich a thrust washer between bolt head and the flanged side of a hex bearing. It's not pretty, but could work in a pinch.

There are many ways to get out of buying a lathe, but there is so much more you can do when you finally get one, why keep putting it off?

We have access to a lathe; I was simply wondering if anyone sold the things so we wouldn't have to make them ourselves. Off-the-shelf parts are a huge benefit. It's not that we can't do it otherwise, it's just that one of the things we're going to be shooting for with this design is simplicity and ease of construction, which custom-lathed parts don't really fit into.

Ultimately, though, we'll likely end up lathing the things ourselves. That's what machine shops are for. I just wanted to make sure that we don't go with that if there's a way to avoid it.

Why avoid using the machine shop you have in house?

It's not in-house.

Sorry for the off-topic post:

A lathe is a machine, it is used to Turn parts, not lathe them.

Very unlike most other machining terms. Can anyone think of another machine where the work it does is not the name of the machine?
