I found these tap and drill charts stored away in my pc and thought they maybe of some value to those requiring tapping and clearance drill information.
As it was in pdf format I could not load it. John has been kind enough to get it on.
If you click on the pics they will blow up, not as in explode with a bang.
Note from JRinTawa
May I suggest this would be a handy place for other similar info and charts.
