Hi Brunswick Brawler

Where these fit on to the cabinet, mine has been hacked away.
At the footrail end, where the cabinet sides are correct, there is a 7 x 10 mm wooden edge sticking up.
Looking at the new rails, the RHS one would normally sit on that as described with the routered section going over the glass and the balance overhanging the side.

The problem is that only a small section of the side has that 7 x 10 edge, and other in sections the wood is up to 15mm below the flat area that the glass sits on. The new wood would be sitting in free air along the majority of the side.

I can either make new rails that can sit over and down the sides of the machine giving me a fixing point and covering the missing wood or try to repair the sides and fit new side rails. I am not sure of my routing ability to do that and any hidden nails will present problems. May have a little play and see how it goes.
