We use two products on the boroscope inspection plugs in the hot section of jet engines:
Agree...The problem is that if the bolts have been heat treated in any way during production, they will loose their strenght throuh overheating.
I can't see a post by flies like a beagle.So OK @flieslikeabeagle explain why you disagree with using copper anti seize or gorilla grease on percussion nipple thread..?
Nipple threads are not that fine and needs something to stop the crud getting in and jamming them.. normal grease is too soft and just gets blown out. You need a loaded grease that leaves a lubricating residue. The flame that comes back from even a black powder chamber is very abrasive and will cut into threads or vents over time. The vents on old percussion guns were often lined with platinum to reduce this wear. You should always take out the nipples and clean them after shooting as some cap residues are quite corrosive (be very careful if you are using old or foreign caps as some still have chlorides in them..).
Nipple wrenches are not that difficult to make if you have access to a lathe. They are basically a tube with a slot cut in them. You need to make sure the prongs are reasonably tough as they need to withstand a fair torque. I make them out out of EN3 and case harden or Silver steel hardened and tempered to blue.. (same as a screwdriver). The Italian wrenches sold by the likes of Krank are often too loose and/or soft to be useful...
Is is a Uberti New model Army or similar?
