Gary DO NOT buy your ring from MECOA unless you want no compression and a very large gap.. I have a dozen here brand new that ALL have huge gaps, The only way to use these in CL is the way Stan Powell did, he sent his sleeves to Henry for chroming, and in doing so make the diameter smaller, this made the end gaps much tighter, and so they were usable, and had compression to hand crank. My ST dykes Engines OS dykes engines and my K&B 40 all have decent compression for hand starting
So get a ring that you can buy with a small or no gap new, that way you can set the gap tight... starting off at .010 thou is NO good
If , as Motorman says, the new guy doing Frank's rings are no good, not round and rough, then I am afraid we will have to look for others to make Dykes rings for us.
