Fine points of drilling bridges

[VGlukhenko@AOL.COM]

Hi there!
I've been using regular drill bits (numberd 1-56), the veray only in few 
thousands
of the inch. Here is the chart:
Bridge Pin Size        Drill No.
        #6                       #48
        #7                       #45
        #8                       #42
        #9                       #36
        #10                     #30

Also I have used high speed drill (DeWallt brand) with PRECISION DRILL GUIDE,
I bought it from Woodcrafters store ($41.95).  With that GUIDE, you can adjust
angel and depth of your drilling to keep it firm.  Also, IT is VERY handy 
tool in
any woodworking projects.

    I hope it helps.
