Fishmouth tubing....take 3

I tryed a combination bench grinder and dremel tool tonight. The two work very well together. First I mark the angle of the joint and the center line.  Then grind most of the material off. This naturally starts to round a groove in the tubing.

Then i used the dremel with a 5/8" bit which wants to center in the groove, as I round the groove to fit the contour of the longerons which is mostly 5/8". A little test fitting results in a fairly tight joint with the appropriate angles. Much like sanding wood joints, it takes a little practice. I feel like I have a good system in place now.

90 degree right angles proved to be slightly more challenging for me, which I was not expecting.
