<VV> Rebuild II

[Dennis & Debbie Pleau]

I had to look it up.  The bolts which hold the case halves together is a 
7/16 x 20 threads/inch.  1/4 turn would then be 0.0125".   A piece of copy 
paper is 0.004" to 0.005"  so you just stretched the bolt the thickness of 
3 sheets of paper.  Take a look at three pieces of paper that's a lot.
