> Think about mounting with a T-Nut and improvise a shaft extension... He said earlier that they have 'non-standard 8 x 0.75 threads' and I don't = know if they make T-nuts with M8x0.75 threads. The chart I looked at lists = that as a fine thread, and I suspect the normal one is M8x1, although that = is also listed as fine, and M8x1.25 is listed as coarse! I suspect looking at the T-Nuts I have that such things are normally made w= ith the coarse thread for the thread size. --=20 Scanned by iCritical. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
