<HTML>Bill: Your are correct. I had a senior moment. The bolts I use are 3/8" instead of 3/16". Bill ......Glassing the Block.....In the past I have used a paste filberglass to "glass the block". Is this acceptable practice? Also.....what size drillbit do you recommend when drilling a new pinblock for 2/0 pins and where do you purchase these bits. My ole buddy who is now in "happy hunting ground" told me to use l/4" honed down with India stone .007 less than 1/4" but I'm sure someone sells such animals now. I try not to rebuild if possible but am about to get back into it and need to purchase a drill bit. Thank you Tommy Black Birmingham, Ala. Chapter</HTML>
