Converting a wallmounted Durst 1200

On my L1200 the plate between the baseboard and the enlarger column is a simple flat plate. I think 4 common washers would be a good substitute for the plate.

If the column is aluminum, you want a load spreader plate, preferably steel for the front column clamp. Same thing for the plate under the baseboard. You need an alloy clamp plate to be approx 3x the thickness of a decent steel plate so it doesn't distort at the bolt holes.
