I have been making ramrod tips using a friends lathe and like them alot so I thought I'd share.
5/16 stock with a 1/4" hole 1" deep in one end and a 10-32 tapped hole in the other 3" long with a 1 degree taper. Since I taper all of my 3/8" ramrods to 5/16" anyway I figured this have a nice (functional) period look to any of the rifles I send out.
The picture shows one mounted, a standard 3/8" brass tip for comparison and a couple of others.
