Brush Honing

An Engine builder needs to understand that there is a vast difference between rings that are merely seated and those that are seated with some attention given to detail. This is true for any piston-driven vehicle or equipment. If incorrectly done, the same basic problems — oil consumption, smoking, and lack of power — that may have prompted the work in the first place remain. Furthermore, correct and conscientious honing is one of the most misunderstood aspects of a successful engine freshening or rebuilding.

:yesnod:Good information Don, thanks for sharing.
 
I had an MGB which I converted to a race car. The cylinders were bored and new pistons (flattops) and rings were installed. When I got it back from the shop that did the work and started it up, blue smoke came out the exhaust. I took the head off and removed the pistons. I got a hone for my electric drill and went up and down the cylinders a few times with the hone breaking the glaze that had formed. I put it all back together and no smoke. Honing is essential after reboring.
 
I'm a big fan of BRM (ball) hones; I have them in several sizes, from 5/8" clutch M/Cs to 4" cylinder bores.
