ARP5935 para 3.6, for type 1, requires Rmr 70 - 90% at C0=5% and C1=.25Rz.
our grinder never met 70-90%.

RE: ARP5935

dho...

This is a reason landing gear components are so expensive: specialized machined finish processes that are jealously guarded!

HVOFis tought stuff to attain a super-finish on. Processes may have to include multiple/overlapping steps, special materials and specialty equipment.

know any shop capable?

RE: ARP5935

Dho... hmmm...

A company that does decent quality landing gear overhauls for USAF 'heavies' [Ogden Air Logistics Center] is Heroux Devtek [pronounced more like 'Aero-dev-tech'] in Quebec Canada.

I am aware that HD has invested heavily in machines/machining tech that could [not 100% sure] do what You need... but sounds like they could be a competitor???
