I ended up getting the KBS 3 step system for frame prep. I completed the 1st 2 parts today: 1. cleaning solution 2. Phosphorizing (?) agent. Tomorrow will be the frame coating x 2. I will then topcoating with por stirling because kbs only has black topcoat. In between I will be working on my subfloor template and cutting.
Thanks Bart. Good point. I may still attempt some drains to the belly like Perry used, but I'll see.
Perry, that back looks well-supported. Thanks for the pictures. I have been under the impression that I would be able to work the plywood in one piece
. If I had known I might be splinting, I would have welded an extra perpendicular support centrally between last two crossmembers. I guess it's still an option, I may just go halfsies on the split.
As for my other questions:
The battery box. The more I have been thinking and looking at it, I think the lip is supposed to go over the subfloor on all sides (instead of just butting up against). Is this right?
Ply outriggers: I also am pretty sure the plywood outriggers (the rear on is seen in the original post) are PO ingenuity. But are metal outriggers supposed to be directly either side of the battery box or is the subfloor properly cut out under the box lip the proper support?
