Fw: marking the block

[Erwinpiano]

Bob

   Ditto.  Have tried a vareity of tricks but the circle works for me.  I've
also gone to the trouble of pre-fitting all the flage screws just as in the
final installation before I mark the circles so nothing left to chance. I
drill for no. one pins and use a  1/4"brad point which really helps with
accuracy. Aim for the middle of the hole!

   Works for me

Best
