Description:

Just as cylinder honing is non-negotiable in piston engine rebuilds, lapping the side housing irons is essential for rotary engine longevity.

Made from 316L stainless steel, this Rotary Iron Lapper Adapter that is meant to speed up the lapping process by using a manual mill or drill press to resurface your irons faces. Use valve lapping compound between the surfaces of the irons. Grease or oil the inside of the lapper to decrease wear on the tool

(Fits 12a, 13b, and Renesis irons from 1973-2010)
