I just bought a partially completed Cody rig off Ebay and the original owner/builder went away from the original plans. I am trying to salvage the gimbal assembly (this is where most of the changes are). And I know why now it cost so little. I guess I need to describe the current configuration first, before I ask my question. The center post for the assembly was made using the "B" section of the monopod, not the "A" section. The bearing is a Koyo 633 with the center post fitting a little loose, but held on the post with a couple of shaft collars (sandwiching the bearing fairly well). Bearing assembly is then fitted into a larger shaft collar with the OD being 3.000inches and the ID being just over 1.000 (secures onto the OD of bearing quite well) with the flat height of the collar being roughly .750 or so.
I know my gimbal yoke will need to accommodate this change. My question is, what is the purpose of the screw contacting the top of the outside bearing race and is threaded through the "L" bracket on the bearing housing in the plans? I am guessing...retention of the bearing in the assembly? Basically, I am trying to figure if this assembly is salvageable to make it work, or should I just bin it and start from scratch, which I would prefer to avoid.

I decided to bin it. Using a little ingenuity and a trip to the bearing shop, I think I came up with an alternate idea for a really stable gimbal assembly. Have to play with the idea for a while, but if it works, I will post pics.
