Stop in for a cup of coffee

Here's a question. Should i weld in some frame connecters before putting the body on the rotisserie?
I wouldn't. I would wait until after you get it all together with full body weight before doing that. Otherwise, you may have the body welded in a configuration that puts stress on the connector welds later from just the normal weight of all the parts.

The blank body won't be warped on the rotisserie.
