Recent discussions on this list have dealt with drilling pinblocks, the problems of heat glazing, etc. Various factors such as drill size, drilling technique, and the type of block have significant effects on the initial torque reading of pins in a new block. If you drill and test, and the torque is wrong, you adjust to get the result you want. A new pin installed with a particular technique, like a driving lube, can drop or raise in torque value over the first week. Do you allow for that? My question is this; What initial torque readings are you, as a rebuilder, shooting for? Your range of "acceptable" readings. (For example, - above a certain torque you would stop and work to lower the torque by perhaps drilling a larger hole, below a certain torque you would stop and work to increase the torque, by perhaps drilling a smaller hole.) Easy Survey! " I strive for _______ to _______ inch pounds of torque in a new ___(type)___ block, and ______ to _______ inch pounds when repinning an old block that is in good condition." (cut and paste the above sentence and then fill in the blanks for the "easy" survey part) Inquiring minds want to know. Thanks, Bill Simon Phoenix
