<HTML>Clyde: The 3/16" bolts from front of plate to back of frame has always held the pinblock together. I always felt better using a "backup" system of glue.  I've never had a problem removing the clamps immediately after bolts secured. The pinblock remains tightly secured.  Thanks for assuring me I'm on track. I appreciate you sharing so I can learn. Thanks , again. Tommy Black Birmingham, Ala.</HTML>
