Hi Gang,
As some recall the 170 Chapter (South Central Pa) has a Chapter project where they took 8 different manufacturers of pinblock and drilled each with 10 different sizes of drill and pinned them. The torque readings were taken in June 1996, Sept 1999 and today.
The data is available in a MS Excel file. If you want it you must reply to MY PERSONAL E-MAIL ADDRESS BELOW. Replying to the list won't cut it, I'll be working the MARC Convention and will not have time to monitor this list.
I'll try to paste the data here for those that do not have Excel or something that will open an Excel file.I sent this to myself first and it looks fine.
Mike
