First things first. Always ware your safety gear. I didn't even notice this disk come apart until I turned off the angle grinder. Thought I heard something hit the wall on the other side of the garage.
I didn't get as much done this weekend as I wanted, but any progress is good progress. I have all the uprights except UR1/UR2. Looking at the drawing it will be easier to put them in after U1/U2 are in place.
Front Frame. Man is that a fiddly bit to work out. I am using the Vodou plans for the chassis. Or I think I am. The front frame would have been the first departure from the standard Haynes frame. The Vodou plans have their own front frame, or show how to add a packing bit to the standard frame. I tried to draw up the Vodou front frame in sketchup with no luck. Either I don't understand, or the numbers are wrong. Either way I build the standard Haynes front frame. The dry saw wasn't much use here. I cut the bottom 26 degree, then used the angle grinder for the compound part of the cut. Next i used the angle grinder to cut the 26 degree wedge out of the middle, then again to cut the top.
The front isn't welded to the rest of the frame yet, not even aligned well. I just wanted to see how it looks.
