Bogan 3050 Tripod Mod.

I originally purchased this tripod sometime around 1978 or so to use with a Sinar F view camera however over the years all my other cameras spent more time on it. I sold the tripod 18 months ago or so.

Early on I became fed up with the little PITF (Pain In The Finger) round handle lock levers on the leg angle support arms so when I had a good opportunity and an idea to solve the problem I modified them with longer add-on extension levers.

I resized the inside of 3 pieces of stainless steel tubing with a reaming tool on a lathe that I had access to after hours at work creating an interference fit over the old lever\'s round handles and then bent and formed the flat sides on the ends.

To install them I thermally shrank the old levers in liquid nitrogen while thermally expanding the new extensions with heat. When ready the new extensions would be aligned and quickly slipped over the old levers. Within seconds the two parts became inseparable.





PITF problem solved!

Wow, I need to get my hands in some hand lotion!
