When
I started doing table-top photography, vertical, or nearly
vertical, shots required putting my tripod on the tabletop and
mounting the camera on the bottom of the riser column.. I used
the tripod this way for a couple of years, but always found it
inconvenient. It was sometimes almost impossible to get the feet
of the tripod out of the shot. The tripod occupied space on the
tabletop, and was always at risk of being knocked over. The feet
surrounded the subject and were always in the way.
I
bought the tubing at a Metals Supermarket store. The vise
is a Lee Valley Tools In-Line Vise that I've had kicking around the
house for 10 years. (They still sell it. See http://tinyurl.com/6d9csz.)
I also bought some 1/4-20 threaded rod and a wing-nut from their Jig
Fixtures department. I cut the threaded rod to length with a
hacksaw and dressed the cut end with a file. I washed the tubing
with detergent to remove grunge from the store, and dressed it
well with a flat file and a rat-tail file file to remove rough
edges.
