Zee,
I've got a set of 1/32" wide parallels.   These come in handy for things like that. My only problem is that they fall down, so you have to find something to set between them to keep them upright.  The springy corrugated snaky thing that Pete described works well for that.  I make them out of old pop cans.

There's also those wavy parallels that might have worked for you.  But a work piece has to be long enough to span a full wave or it won't stay up on those :)

Yep.  The 1/32:aren't used much but when you need them that are great !

I must’ve been on my way back from nowhere and missed the first run. Damn nice Kirk. Love the motion.

Nice gear work there old chap. I gave my BIL the Sherline CNC rotary table a couple of years ago for Christmas. He does clock repair and now when he has to cut a pinion, he cuts about 2-4” of it and then parts off what he needs; saving the rest for the next time.

Not only does this guy produce some fine machining videos, his spider ones have gone viral. Apparently a lot more interest in spiders than machining  :shrug:

Specific Engine Help / Re: O ring cylinders for vertical Steam engines
« Last post by crueby on Today at 06:40:09 PM »
Definitely use the square bottom cut, it gives the ring some room to 'squish' into when compressing it into the bore - does not take much compression to give a good seal. I also use Viton rings, seem to wear very well (always like to keep a little oil on them too). The tables are a good place to start, but as Jason said I also cut it close, then trial fit and nibble away a little more till it feels like it slides in without too much binding. Not sure how consistant the rings are one to the next, and one manufacturer to the next. Fortunately they are relatively cheap to buy, I get them in packs of 25 or 50 from places like Amazon, they carry the whole range of sizes.
