[QUOTE="Trickymissfit, post: 481892, member: 25383"] a few years back the Army was doing some experimenting with electroless nickle processes on M16 rifles. There is one process that allows you to plate extremely accurately (.000050" steps), but is not quite as hard as regular electroless nickle. This stuff actually has teflon embedded in it! Extremely good wear properties, and a finished machined part can simply have about .0005" plated on it without a refitting of the parts. The price tag was $80 for a complete set of internals for an M16 rifle! What became of the project I don't know, as I never had the oppertunity to use any of his plating. I was thinking about doing some spindle bores on machinery, and regrinding them often took a day and a half when hard chromed. gary [/QUOTE]
