I want to drill several 3/4" holes for bench dogs in a laminated workbench
top (prior to assembly) that will be 3 inches thick.

Right after posting this message, I discovered Forstner bit extensions.
They are expensive ($29 each). Does anyone have any experience with these?
I am little skeptical of the two allen screws used to hold the Forstner bit
in place in the extension.
