I haven't done much the past week or two except acquire bender parts and was able to paint and assemble it.
I ordered up a package deal on a probender3 which comes with a 1-3/4" die. I actually didn't realize it came unassembled or would require welding, but I didn't mind. It comes with the main arms, pivot arms, and a couple "feet" that you use to create a base by welding some 2x2 rectangle tube to.
It gave me a reason to break out the welder again and acquire a nice new hvlp spray gun along with paint and primer.
There's the base after welding it together.
I do have a tip for anyone else using this bender. I tack welded the base together after assembling everything to make sure it worked ok.
The big bolts on the bottom use some round tubing as shims to keep the two arms the correct distance apart. When I disassembled it for paint, I couldn't get the tube spacers back in because of the paint buildup. So I needed to grind the spacers down a bit which took a long time to get right. I'd put a extra washer in the assembly next time before welding to reserve some space for paint.
If you can believe it, I haven't had a chance to try it out even once yet...Still working on the slider stuff and started coaching my sons t-ball team which is a lot tougher than it sounds.
