There's nothing more nerve-racking than ordering a set of special order pistons . . . especially when they'll run in rare, vintage Axtell cylinders . . . and there's probably NO RETURNS on the pistons? I came up with some special bolts to get the cylinder properly mounted to the boring table.
They require +.005 to +.007 running clearances (measured at the bottom of skirt) and Venolia normally figures the clearance into the piston size. I requested my specific piston size, I wanted a standard manufactured ring size (in case he just needs to re-ring it sometime?) and I requested the rings come with the newer style Hastings 3-piece oil ring. Cast compression rings. The boring came out successfully (no other option on this one) - now just hone for fitment. I'll probably give 'em a heavy 6 thou . . . he can break it in easy - and good warm-ups from then on . . .
