It never occurred to me that there was an early model Weldon that did not have a floating spindle.
Right now I want to make sure that all the air that gets through the housing is able to get through the bushing. That way there should be no chance of air pressure deforming the bushing.
Once that is achieved, sealing the ends of the bushing/housing joint makes sense. If I choose the right sealant, it will stop air loss and tend to keep the bushing from being deformed. I want to be able to push or press the bushing out.
There should be no problem installing the sealant. If I put all but a half inch of the bushing into the housing, I can butter the remaining bit with the stuff, and on the other end butter the inside of the housing. The two sealants that come to mind are any of the gasket makers, and RTV sealant.
Another option to sealing the ends would be to groove the bushing for O-rings.
What are your thoughts on sealing the ends?
