Well I have taken the plunge and am finally in the process of building sliders a la George. I have gone through the archives and searched past threads for more details pertaining to the sliders. I have made the decision based on the fact that I have some time to work with, the necessary tools, metal at reasonable costs, no money for Slee's beautiful design and a big f-ing heavy bag in the shop to take out the f-ups on. I cut out the plates yesterday and some of the outriggers...thanks PowerMax 900. I am waiting for the other outriggers which I brought to a machine shop to have the compound angles cut. In the archives I came across a post or two mentioning slight problems with the fitment or design and that one of the PDF images was reversed. Can anyone elaborate on this? I would like to hear the advice of others who have built these sliders. I am planning to use 3/16 inch plate and tubing all around with 2x3 inch outriggers and 2x4 inch main sliders. I will then add a round tube for door protection a la Slee and Hanna...if my hands are still able to weld after punching that heavy bag. Oh and what about the U-bolts...anyone use straight grade 8 bolts with backing plates, how about a source for the u-bolts. Advice ? ? ?
