Some pics from over the weekend boxing S-Curve frame I like to use a single strip of 4'X4" 100 thick mild steel and I also remove the center mount support and inset it for double support in the center of the frame, I also filled all the mounting holes not needed for the project, Dont mind the dirty floor I used the truck shop this weekend while we were closed for this part of the project gets bad in there during the winter. I will post better pics when it gets back over to the toy box this week.
