Dave,The cutter looks great. How different are the inserts from the Arthur Warner HSS ones. would they Fit in the same holder? Maybe A question for Steve.Art
Hi,the cast iron rings, slotted are held closed with a thin brass thread on a mandrel which has a screwed washer in front of it to tighten one or more rings and keep them closed; the exact outer diameter required is then finished on the lathe as it is generally made; But before this finishing cut, I give a very slight eccentricity on this mandrel (about 0.1 mm) on the side where the ring are cut to reduce the thickness at this place, what is expected to distribute the compression of the ring evenly over the entire perimeter. I saw this trick on piston rings of vintage engine (10cm3 Micron sparkie engines) and now I try to reproduce it on my own engines !
