The backup plan will be to use the miscut pieces, and hand cut one larger piece to fill in the bottom section. Have plenty of leftover tubing. Would not be perfectly round, though.

That's what I meant to do with grinding.
There's not too much that needs to get off each mating surface to close the gap at the end.

A week ago, the laser company said they would discuss with the cutting technician and get back to me with details, so I know how much titanium to order.

Haven't heard one peep. :smt012

Just sent an email saying I would accept the refund. Can't keep waiting.

Will try to cut a larger piece by hand to finish the circle. If it's too far off, might need to trim down all the pieces.

So close, yet so far away. Stay positive Pete. You'll get this issue resolved.

It looks like you should be able to make the last piece knowing what the angles are and the measurements needed. Perhaps a template first to insure it's correct and then the actual piece. I can see a belt sander being useful in getting to the exact fitment.

Need to set it up again. Then measure short and long gaps at the center (for the bottom section).

Used to have a pipe program that would print out paper templates. Hope I can find it. Would be really great to have the template cut by a digital paper cutter. Not sure how accurate I can be by hand.

And give it a try with hand cutting, except you're shakin like an 80yo ...
That's enough to check if it fits.
On the other hand: whats the sense of testing with paper if the 3D cutter cuts whatever they like ?
