Changed the design to a one piece main hoop (more strength). Got these two bent and the mounts cut out, deburred, and bevelled. Maybe tomorrow I can notch these out and start welding the mounts on. I'm going to town Thursday to get a band saw I bought, some lumber and steel stock. Hopefully by next week I can have a few of these made. I'm keeping one for myself to torture test, and the others will be sent out to people who want to test them. I'm thinking $130 for the test models, including hardware (may be more if I have to ship it to a crazy location). Once these have been run through the ropes and beaten on, I will make some more if nothing has to be changed on the design and they will be closer to $200. I will guarantee the welds and material, but not the mounting hardware. I ordered a bunch of hardened bolts that should be stronger than the stock mounting bolts, but once again, I cannot guarantee they will hold up to the abuse. I'm looking for 1-2 more people to test these for me, let me know if you are interested.
Getting the TIG dialed in now... these two washers form the bottom part of the mount that the bolt passes through.
