The edge of the upright piece. I have to bop the tube into place. They are not bent exactly. I'll get a pic in a few and you'll see. 

I want to replace that one piece with a slightly taller piece that has a raduis milled onto it. That would cut down or eliminate the scuffing. For now, I've got a bit of a radius on the edge now, but, it really could use a more gentle, consistent radius to ease the tubes into place. 

But other than that, I'm really liking the setup. I've got a pretty good work flow going  

 Agree--the concept is good, but it needs a better (refined) design. Certainly a radius would help immensely, as would  a good polish to minimize abrasion.

A good jig is worth its weight in gold... 

 Here's what I mean. I have to "finish" the bends to get the ends to meet.  https://pomf2.lain.la/f/axle0dyt.jpg https://pomf2.lain.la/f/axle0dyt.jpg 

 Oh...wow...that's a mile alway. No wonder you get the abrasion trying to get it aligned.

Why is it so far off? (Feeling like you need a jig to ensure the initial bends are spot on...)
