Thread: Oils
15/08/2022 22:15:47

As Robert says oils with certain additives have a detrimental effect on bronzes, we run a new Leak compound in the museum boat and we're instructed in no uncertain terms by the maker to only use straight oils because of this very problem.

Thread: Difficulty in repairing a bonded 5mm green polyurethane drive belt

I have had the same problem with the drive belt for the UPT in the end bought a new length and it joined perfectly. So its possibly an age thing. Out of interest the belt did nearly 20 years!!!

Sounds like a good time to give it a birthday service and reoil. You say cord I presume you mean material cord. You have more choices these days in types of material to use, why not go for phosphur bronze , fit and forget.

Thread: Displacement lubricator

A small amount of steam condenses in the lubricator body therefore displacing some oil to do the lubrication.

Thread: Press fits for bearings
27/07/2022 17:07:56

I think that fitting bearings by press fit at home is a task that requires a bit of luck as the greater percentage of us do not own certified inside and outside measuring instruments. the thing to remember is that the bearing is near frictionless so the fit does not need to be as tight as our mind would have us believe. The problem with overnight fits is that it shortens the life of the bearing by quite a dramatic amount. A tech man from SKF once told me that for small races (under 1 inch od) it is better to have a sliding fit and a DROP of loctite so there is no compression on the bearing case.
