Re Chrome a sleeve
If it was as easy as using a brake cylinder hone then everybody would be doing it. Does not a brake cylinder piston have an 'O' ring fitted. So a little bore inaccuracy will not matter. However. if you are an experimenter and have to scratch an itch go to it. If your engine is an ABC engine with a tapered bore save your money on the hone, it will not do it.
