You might hope for better life from using a metal powder filled epoxy to fill the gap, and that's no great shakes either. Pick a bigger bush and reduce it, if you possibly can. Brian W What??? Is "cowboy engineering" the newest politically correct version of political incorrectness in describing a "kluge" or generally unacceptable practice? Peter ;-))) You're gonna upset some guys who're real good with .44s .44 is for sissies, try .500 S&W magnum. In any event knurling isn't a good solution for something on which your life may depend. There simply isn't enough surface generated by knurling. I have done it for toy steam engines, but would never do it for something that has significant forces applied. Bear in mind bronze and the tube material have different temperature expansion rates. If you don't need to apply a lot of force to it you can use a prick punch to stipple the outside of the bushing if you don't have access to a lathe and knurling tool. If you choose to make your own bushing bear in mind there are different bronze alloys each with its own characteristics. I use phosphor bronze for most of my bearing applications. Dan, U.S. Air Force, retired AFAIK, the .44 was the percussion cap wheel gun that became the .45 Long Colt, a/k/a The Gun That Won The West, and extremely popular amoung cowboys during the brief period of the Old West. In any case, I agree with you about knurling. Peter Oh, THAT 44 Mine is a replica Colt army. Did you know if one doesn't crimp the caps correctly they all drop off when the first one is fired? Not that anything like that ever happened to me or anything. Dan, U.S. Air Force, retired |

One also quickly learns to turn the gun upside-down whilst re-cocking the hammer after each shot. Otherwise you risk having the used cap drop down and jam the action. Vaughn |

Don't bother michael. I once drove 600km getting a bushing sorted out. the first time it was too tight. trimmed off a bit. slightly too loose. worked out the fit needed, next time a perfect drive fit, just tap in place. 600km to get it just right. the project now sits in my backyard workshop. do it properly or the bushing will wear prematurely. if you cant get one locally I can machine one in phos bronze and post it to you. is easy. you've probably still got my email address.
