Hi Terry, Torque tends to be very even at about 110inch/lbs, as far as you can tell with the primitive torque wrenches. I have always gone with 2/0 blued pins. I may have done one in nickle but am not sure. Just finished an open face block and it is nice. Time elapse varies from 3 or 4 days, to 3 weeks. depending weather the case is being refinished. Have not noticed a big difference in torque. I'm happy with the results using 2/0 pins. so I doubt that I will change. The times I have measured torque, has been after I have chipped and tuned several times. Regards roger At 09:52 PM 2/26/2003 -0500, you wrote: >Hello Roger!
