My RF81 included 6 good wheels and two damaged ones and I would like to complete the second set. 1 outer was damaged and both inners but I have a spare outer. I need the two inners. The two center sections are fine. Anyone have any spare barrels laying around their shop? It doesn’t appear that current Compomotive sells replacement parts.

Following.....
I ended up with a bunch of 3 piece wheels from several different manufacturers including Compmotive, it would be good to know where repair parts can be found.
I have a pair of inners, To make a 9 inch wheel, I think. I also just replaced my fronts, So I don't really need those.
Lee R sold me some Mad In wheels. Their website says they can supply Compomotive barrels. The wheels I have don't interchange with Compomotive, different bolt diameter.
I think I've heard that either or both Keizer and Jongbloed can make compomotive wheel halves, so you might want to look there if other sources have dried up.
I have purchased compmotive inner halfs from these people. Excellent quality.

It appears the oring that was used was really square with a lip on one side. Since I doubt I will find anything with that cross section can I go back in with just a round one?

It probably was round when first assembled many years ago, but over time it has taken a set and become square I would guess. So I would say use another new one that is round. I only put RTV in the corners where the rim halves meet the center after the wheel has been assembled and hardware torqued up.
Replacement barrels/rims are available from Image Wheels:

In my experience, ANY between-the-segments O-rings are troublesome. They always take a set (stress-relax) over a few years at most and leak. The much more reliable technique is to assemble and torque the wheel fasteners with the pieces dry and clean with no O-ring, and then use RTV (I use Dow 832) in the crevices between the components. Unless the RTV gets physically damaged, wheels sealed that way never, in my experience, leak.Quote:

I thought I remembered you mentioning something like that and I couldn't find it. As usual, you have probably forgotten more things that I ever remembered!
