Fine tooth (10tpi) hole saws make a huge difference when mitering thin wall tubing. It was the difference between a smooth accurate cut and the saw grabbing and coarsely cutting through the material occasionally breaking a tooth along the way.

I Bought this over a year ago for another project that is now on hold. these benders are relatively inexpensive and do a great job of easily bending even large diameter tubing. I'm doing 1.375x095 at the moment and was surprised at how easy it was to bend compared to the Diacro bender I had been using. In all fairness the Diacro was never meant to bend tubing larger than 1 inch or so. However with the JD I didn't even have to use a cheater pipe on the relatively short handle as it gives you that much leverage. And with the added leverage ratio also comes more precise control over the bend.

Here is the first bend of 1.375"x.065 wall. it's a 6.5" Center line radius with a 1.375" miter on each end. this is the center brace for the front swing arm which is the first frame piece I decided to make. That decision was based mostly on the fact that the other components are still in the design phase and subject to change where as the swing arm is done the drawings ready to go. Below is an image of the weldment model of the front swing arm so you can see where the parts I'm making here fit together.
