>Does a new cork block need to be flattened before use? > If so, what's the best way? You could sand the cork surface with sandpaper on a piece of glass to get it straight. Use the rounded edges down for sanding broad surfaces and the square edges for getting into inside corners. My blocks are made from 3/4' plexiglass blocks. Some are faced (1/4 sheet sized) with back rail cloth for taking down the surfaces primarily. The rest are faced with bushing cloth. These don't warp. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
