You sure about that? If you use a template made of that melamine stuff to locate the ribs and tape the board to the melamine it works quite well. Cut slots into the melamine and the ribs sit in the cut slots and are then sandwiched to the soundboard locating them well and preventing their movement while the bag vacuum clamps it all together. I'm assuming ribs that aren't flat. Works quite well actually.

Ribbing a board today I discovered that my pneumatic clamps (firehoses) had all sprung leaks to the extent that my compressor wouldn't keep quite enough air pressure (argh). So, while I did fashion a remedy for the short term I'm shopping to replace the fire hose material with something a bit more air-o-dynamic. Any suggestions? David Love www.davidlovepianos.com
