Abstract
A method and a drum made of a moldable material, such as fiberglass, in a cylindrical form and having a low friction material coating the inside thereof and having a sound opening and baffle formed in the cylinder, for enhancement of resonance. The cylindrical drum is made through the utilization of the low friction material on the interior of fiberglass, and the two are bonded together because of the use of a paper on which the low friction material is a coating.
Claims11
A method of making an acoustic drum, comprising the steps of snugly positioning a low-friction MYLAR coated paper endlessly around and onto a mandrel and with the coat in contact with the mandrel, applying a uniformly thick layer of an uncured fiberglass-laden material in liquid form endlessly onto said paper, curing said fiberglass-laden material to have it adhere to said paper, and sliding the resultant fiberglass-laden material and paper off the mandrel by virtue of said low friction MYLAR.
A method of making an acoustic drum, comprising the steps of positioning a polyester coated paper endlessly around and onto a cylindrical mandrel and with the polyester coat in contact with said mandrel, applying a uniform thickness of an endless layer of an uncured moldable material in liquid form onto said paper, curing said moldable material to a solid form to have it take the cylindrical shape of said mandrel in a rigid body and have it bond with said paper, and sliding the combined said bonded moldable material and coated paper off said mandrel.
