@WoodCutter4, I started with Bar’s bolt on frame when I got my kit last year. But after top beam split under one of the motors, I went with a 10 ft superstrut top beam, with a vertical motor offset of 619mm. I have pictures in this post. Up against the wall Frame
The frame is at 15 degree angle, waste board is 3/4 MDF, sled weight is 24.5 lbs.using the ring linkage in a top feed chain configuration.
I hope that helps, cheers.
