James: I also use the Bolduc 5-ply maple, and my experience mirrors yours. Average torque after a year is about 100-110 ip. Initial torque is in the range of 140-160 ip--starting friction higher then leveling. Paul In a message dated 2/24/2010 5:44:07 P.M.

For the record, I like to see something in the range of 120-145 inch pounds on one of my rebuilds using a 5 ply maple block. It does tend to settle down to around 90-100 inch pounds after one year. -------------- next part -------------- An HTML attachment was scrubbed...
