brucea4 Posted March 14, 2020 Report Share Posted March 14, 2020 Hi gang, Where can I purchase a " fine grit polishing stone " to smooth out my gouged up tower on my M60 opp-rod? I tried Lowes, ACE, & Harbor Freight with no luck. Any other information or tips on performing this operation will be appreciated. Link to comment Share on other sites More sharing options...
MG08 Posted March 14, 2020 Report Share Posted March 14, 2020 the gouges may need to be smoothed with a fine file first - the item you are looking for is something like an "india stone " ( at least that is what we used to call them.) You might try McMaster Carr too. fine emery cloth on a block of wood may also work. Link to comment Share on other sites More sharing options...
DARIVS Posted March 14, 2020 Report Share Posted March 14, 2020 Use a fine needle file, then a sanding stick, then cold blue. The depression of the gouge cannot be replaced, only the burrs at the edges be brought back down to the level of the surrounding metal. Too much metal removal will only make it worse. You just want to get rid of the burrs. Link to comment Share on other sites More sharing options...

DINK Posted December 7, 2020 Report Share Posted December 7, 2020 Gunsmithing supplies like these stones are what Brownell's exists for. Their catalog is amazing but is likely to cost you a lot of money. Link to comment Share on other sites More sharing options...

Countryboy77 Posted May 18, 2022 Report Share Posted May 18, 2022 If that were mine i woukd not only clean up the tower but also the sharp edges on the bolts camtrack it rides in as it shoukdnt be eating that up like that. A little grease couodnt hurt. I wonder if its properly hardened? Link to comment Share on other sites More sharing options...
