Stright holes in frame

I need to drill holes thru top and bottom of a frame .Is there a trick to making sure there straight and line up.

 

If you can, block your frame so that it's level, and use a bench top drill press with a long bit, or drill bit extension, sitting level on the floor....

 

Drill a straight hole through a block of steel with a drill press then use the block of steel as a drill guide on your frame.

 

Careful lay out. Drill small hole on bottom so the bit doesn't walk around and it Will follow that pilot hole.

 

We've got a winner!!

 

That was in a magazine a few months back(Street Rodder).

 

Find someone with a magnetic base drill press
