Waterhouse stops?

You can drill a hole or file a flat. Otherwise with temperature and use they will rotate on you. That's where I got my rack and pinion too. Four pinions and two 36" racks, $100.00. Beats buying a $5000.00 camera though doesn't it? Racks, pinions, bellows, ground glass, after you get that taken care of it's wood wooding and lots of it.

Hi Jim,

I have the same problem with the set screws for the gears on my 8 x 20, and have yet to resolve the situation. I tried flattening side of the brass rod that the gears go on with a file - it does help some, but they still seem to work their way loose. I think the drilling a small hole is about the only way to go. I have thought about using some glue or Lock-tight in the set screw hole once it's tight, but that would make it more or less permanent.

For what it's worth, even with the set screw loose, the front geared standard is still pretty firm on my front gear rails and it doesn't seem to make much difference in making the exposure.

Something I noticed when changing camera mounting screws on a Majestic tripod was that not only was the shaft into which the set screw fit dimpled for a good grip, but that they used two set screws, one behind the other, to keep things from loosening. Both set screws were pointed on the end, and the dimple on the shaft was cone-shaped.

Blackening - in olden times carbon black was used, which basically is soot from a candle as far as I can understand. I have blackened lensboards, etc to good effect.
