I wanted to be able to lock the work-support carriage in place to
the pipe bed, so I drilled holes and installed T-nuts in the walls of the
box before gluing it up. After the glue had cured, I cut the 16-in. box
into four sections—two longer sections for the carriages and two
shorter sections for the pipe housings in the bed.
I added spacer blocks to the top of the drill carriage to raise up and
support the drill. I took advantage of the holes tapped into each side
of the drill handle to screw the drill in place on top of the carriage.
By adjusting the drill in place with shims, I was able to get it set to
cut holes perfectly centered into one end of the turned posts. I also
drilled a small pilot hole through the back of the boring jig for a
screw to hold the other end of the workpiece steady.
