mitering seatstays different ways

[aplomb]

Hey folks long time lurker minimal caller...

I am trying to miter my seat stays in different ways. I am looking to do this. I have ideas how to do it? nervous about making more scrap metal..
I am using a Alex Meade st/cs jig to hold things and it works ok for what i have done so far but this is different.
my little rockwell mill can tilt the head 90Deg so that helps

I've done this numerous times. My mill has a horizontal spindle but before I bought this one, I had a vertical mill and a Bridgeport 90° head that made it easy. If you're worried about it, set the stays a little wider than you think they need to be and make a cut. That way at least you haven't cut them too short. The only caution that I have for you is that it's a LONG cut and your fixture had better hold those tubes tightly because the holesaw is going to want to rotate them in the blocks. The cut is long enough that you might have to back the cutter out half way through, snip the waste and re-engage. If you're feeding it manually, take it easy when the cutter makes contact with the tubes again.

That's also a pretty easy one to cut by hand. I've done several that way as I wasn't set up to machine cut them.
