Servo Swinging Arm. We have found that inconsistency in swinging arm poundage is due to oil getting on the surfaces of the Ferodo linings. We want to try oily cotton duck instead of Ferodo. Will you please fit up 20-G-IV in this way so that we can see whether this cotton material will stand the load and whether the friction setting remains put.
