Hope everyone has had a great Christmas and are all working the excess off. Does anyone here have advice or used Slaters Plasticard nylon brake shoes for loco driving wheels in Gauge O ? Reason I ask is because the clearances on the 9F five foot diameter driving wheels is extremely tight between wheels particulaly with the brake hangers fitted, I cannot find images or any refencesof them being used so wondered if anyone here knew. For the record I need BR Standard design brake shoes and I'm a bit unsure if the Slaters product is suitable for the 9F build. Any advice greatfully recieved.
