Hot dang, hot topic, hot everything except the weather. Ok, I see by the responses that I wasn't too far out of the circle. Blue chalk seems to be a good try, but I will go looking for the Crayola stuff, too. Now, I just recently moved the air compressor into the basement, ran the line up through the floor, bought a $50 air powered die grinder at Home Depot and chucked an egg shaped wood rasp in the end of it. This has done a faster job of fitting this pinblock than anything I have tried before,(except an electric router, which caused some nerve damage from the vibrations of fitting a very large block, last summer). I begin by cutting a shallow channel along the middle of the pinblock flange-face, so that I only see contact along the top and bottom edges of the pinblock. As I progress towards a closer and closer fit,(which goes rapidly due to the two "strips" of contact being the only place I need to work), I begin to see contact in the center, where I had dug the channel. Once I have an unbroken line of contact on at least 2/3 of the face surface, I am done. No more than a 1' gap between contact points anywhere along the flange, and no place where one of the three lines doens't touch. I use the grinder on the flange face, and use a small sander with 50 grit belts on the top. Once the block is in contact with approx 30% of its surface, I go with just the sander, as it makes a larger contact area and the fit seems to get close, quicker. The grinder has virtually no vibration, it is very light, and with a flexible cord, quite handy to use. Regards, Ed Foote RPT
