Re: T-cut recipe change
If you have a close-fitting needs-to-be-a-good-fit steel-pin-in-bronze-bush arrangement - perhaps a plain bearing in a motor, or even a tuning spindle - and the thing is a little tight, then a little T-cut mixed with oil makes a good lapping compound for easing things to a really nice fit.
I found this out in a context where the fit _really_ matters. You can lap the clearance and judge it by the feel of the shaft in the bearing.
