TBC bushings for Cambridge

or Churchill or El Grande... is there such an animal? I checked around, but may have missed something.
With such a high-end pen, I'd think that having precision bushings would be a necessity. I have a Cambridge that I did on a mandrel, and it is ever so slightly OOR.

There are only three places that have ever sold tbc bushings to my knowledge.

Penturnersproducts used to sell them but are not currently offered and are not likely to be for the foreseeable future.

They do carry the roman harvest bushings at a nice discount. You could either opt to make the roman harvest kit or see if these bushings will fit well enough in the tubes to use calipers on the sizes. I have both sets but neither kit nor tubes.

You could also solicit classicnib or lazerlinez to Ask them to consider offering bushings for the Cambridge kit.

I'm thinking I might just have to chuck the barrels up between centers with no bushings. I don't trust using stock bushings between centers.
That is, if I can disassemble it without tearing up the center band insert.
