<strong>FoMRHI</strong> Com. 34 ON BENDING WOODS R. Hachez Having noticed several open letters in Early Music and elsewhere, inquiring about bending of crumhorns, I thought this piece of information might be of interest to a few builders. The U.S. Dept. of Agriculture published a study about the bending of wood entitled Bending Solid Wood to Form, Edward C. Peck, U.S. Forest Service, Forest Products Lab, August, 1950. In essence the conclusion reached was that wood was most likely to fail in tension when being steam bent. The means best devised to combat this failure would look some what like the accompanying sketch when applied to the crum horn. \JOCÌZ.V- PlfcCt Fo^n Mfc-r/V«— f>T^.AP ^TOV bLOOC The idea being that the block on the end of the strap is placed so as to accomodate the length of the work piece before bending. It is kept in place during the bending operation and afterward until the wood is set. It is plainly apparent that most of the wood must deform by -24-
compression, thereby avoiding tension and shear loads usually responsible for failure. The test lab reported reasonable success in bending 3/4" thick oak boards to a radius of about 2 3/4". This did involve some experimenting with steaming time though, so a little experimenting might be necessary. Also it is worthy of note that this method is well within the technology of the 15th century and long before. <strong>FoMRHI</strong> Corvn. 35 AN IVORY SUBSTITUTE R. Hachez Having read quite a number of letters requesting information, etc. in several publications, I thought the following might be welcome. There is available a very good bone-ivory substitute called "#454 Ivory Paper". It is a phenolic resin and paper high pressure laminate about equal in hardness to bone. It is marketed by Angus-Campbell Inc., 4417 South Soto St., Vernon, California, 90058. - Tel. 213-587-1236. Its originai intention is as a knife handle material and it comes in sheets 3/16" thru 1 1/8" thick, 36" square. They will cut it for you for a fee. I have seen it "scrimshawed" on a knife handle and it is almost indistinguishable from bone in color and texture. Cost - about $4.00 per pound. -zs-
