Hello All, I wanted to share some insight into veneering common piano parts. My shop commonly veneers lids as large as 9' as well as manufacturing new lids, carved legs, etc. That being said, I am offering some of my services to the industry as well as some advice about veneer in rebuild work. When a piano needs veneer replaced in areas, most people use contact cement and clamp it in place. This can NEVER under any condition work. The reason traditional contact cement does not work is because it "creeps" or moves forever. It's like laying tile with rubber. How do you grout it? The first time the veneer moves with humidity it loosens or cracks. Contact cement often peels in time too. A simple test, take a few drops of your contact cement on a piece of glass. When does it get hard and brittle? The Solution: There is a new product out by joewoodworker.com which is a green 2-part contact cement. The reactant causes it to harden in a few hours, and proper repairs can be done. The preferred shop technique is to use white glue. Elmers is fine as long as it does not say "glue-all" on the bottle. Using white glue, a caul (fitted form) should be made, and then a thin piece of foam rubber is used over the veneer to compress between the veneer and the caul upon clamping. That piece of rubber takes up any imperfections in your caul and comes right off when done. (foam insulation works too.) Here at our shop, we have a large vacuum press table which can veneer both sides of a lid at once. We lay up all substrates with either white glue, epoxy, or eurea formaldahyde glue (similar to weldwood.... also used by Mason & hamlin to make cases). Veneers are matched, sliced and fit, taped, and made into large sheets. Glues are layed on veneer and substrate, and placed into the press. The press insures perfect pressure on all surfaces and curves too. If large jobs are needed, we can handle them for you, simply call Mark at 434-993-3919. We carve any style piano leg, we make filligree racks, and offer the industry gilding, bronze casting, and inlay. Anywho, enjoy the pictures and visit the website if you are interested. www.carvedpianoparts.com _________________________________________________________________ The New Busy is not the too busy.
