Final coat of jbweld on the back plate.
Closeup of the edge of the hole, see diagram legend below image.
The RED arrow is pointing to where the profile of the material meets the top (light gray is the edge of the hole, darker is the top bit). The GREEN is pointing to the JBweld that's been built up. The BLUE is pointing to the metal that's supporting the jbweld (the original plate.)
I hope to sand this down for the last time tommorow night. The next step, obviously, is taking a day off of work to make it to the powdercoater. I'm pretty confident they can powdercoat over the gray 'stuff' that's on the rest of the frame. And they can't, it'll probably come off in the 400*F oven. So keep your fingers crossed... maybe you'll get a few interesting surprises in the 2 weeks that this is going to be at the powdercoater.
