Re: *fast* film/Hale Bopp

|1/4-20 bolt (with a 1/4-20 socket in the knob) so that you could

|like that would do as a makeshift slide bar.

Dang! Why didn't I think of that. I *two* of those now - one was with
a hot shoe to bring a strobe off to the side of my Crown Graphic 4*5
camera, and the other was to adapt a HoneyWell Auto-Strobonar to the
Realist. 

The big problem of course is that in both of these the captive thumb
screw mounts onto the tripod and then goes on up to the camera base.
So when you can move the flash adapter back and forth, but not the
camera (oops). 

However - 

Since I have two of them, I "uncaptived" one of the screws and stuck it
on the other bar. Voila! Now I can move the camera back and forth 
maybe 3". It would be more, but the camera bangs up against the screw
coming up from the tripod. I also need to get a nut to tighten down
the tripod screw onto the flash attachment - I gather from the above
I'd need to look for a 1/4-20 nut.

Another alternative (if such a nut can be found) would be to MIG weld
it to the base of one end of the flash bar, giving a full length slide
back and forth. This give a pretty big moment arm, though, with the
tripod attached on one end and the camera way out on the other end, so
you'd probably want to try to keep things screwed down as close together as
possible for the particular separation you are looking for).

A great suggestion!
