Dear Vandervell, I attach a drawing of a fabric friction disc which we at present use in a small servo motor. We want to try a dry metallic friction plate such as we used on the 20 h.p. Rolls Royce clutch for replacement purposes and which you supplied to us. You gave us some strips once before but we never got any results from these. If you could let us have two pairs of discs these would suffice for experimental tests. Yours sincerely, | ||
