[Boatanchors] Drilling Holes Questions

[William Cromwell]

Hi,

I get good results with the center punch and a hand drill. I clamp the 
work in vice to hold it steady. It only takes a little experience to 
hold the drill perpendicular. As some other have said, use a smaller bit 
first and the shortest bits you have.

A low end drill press is on my radar anyway - just to make it easier :)

73,

I secured the chassis to the moveable table, and simply used the x-y controls to move the table right under the drill bit.  Beautiful and precision work even for a newbie builder like me.
