Quoted from Scoot:I no longer use "C" clamps on my rotisserie anymore. I just take 4 one inch wood screws with washers and screw them into the ends of the playfield through the perforated angle. This is much more secure and eliminates the issue of rotating the rotisserie with the "c" clamps installed. It also raises the playfield up off the perforated angle by about half an inch, to prevent wires and gi sockets from being squashed out near the end of the playfield.
I have been doing that for a while since there are always parts in the way on the back side of the PF.
The PF is really more secure like that anyway.
