My next task was to finish the fuel and brake lines under the car which meant putting the shell back on the rotisserie. The rotisserie consists of a stand and support frames on either end of the shell. The support frames bolt onto the shell and a tube welded to this frame slides through a slightly larger tube on the stand. Here is a photo from when I first built the rotisserie :
Previously I was using a single long bolt inserted vertically through both tubes to stop the shell from moving/rotating but the last few times I've used it, I noticed that the holes in the tubes were getting badly rounded out so I wanted a better way to hold the shell in place before it failed.
I cut off the part of the support frame that was stuffed.
Using two sheets of 3mm steel plate, I drilled a center hole and drilled 8 holes equidistant from the centre. I then drilled around the centre to make a enlarged hole (to fit over the round tube of the frame) and die grinded it smooth.
The plates were slid over the tubes and I welded one piece to the support frame (that bolts to the shell) and one piece to the stand.
There is a bolt at the top and bottom of the plates and this setup still allows me to rotate and hold the shell at 45 degree increments but it's just much stronger than the old design with a single bolt inserted vertically through the tubes. When the shell is on the rotisserie and nothing heavy like the rear subframe is fitted so the shell, it is easy to rotate the shell by hand and hold in place while I get someone (normally my wife) to insert and tighten the high-tensile bolts.
I still use the piece of rebar & SHS bolted to the end of the tube for leverage to rotate the shell.
