Does that sound familiar?

MIKE, for crissake!!! aaaaaaaaaaaaaaaaaarrrrrrrggggggghhhhhhh!!!!!!!

post the dimensions you need and I'll machine you a new one.

mINE DOES THAT aLL THE tIME!!--jERRY

we should make it an internet project.
absolutely everyone in the world with a lathe makes him a new bushing
insert and sends it to him.

maybe after the 80,000th bushing arrives it will sink in that in
aircraft you do it properly or not at all.

(have you been too embarrassed to ask for a bushing jERRY?)

If all else fails make it too big and hammer it in place?

That method is generally recognized as cowboy engineering.
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.

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.

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.

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.

And then you're left with trying to decide whether scrabbling on the
ground to pick up caps and try again, or to get a new batch out of the
tin will be less obvious to onlookers.

Generally, they won't notice, being doubled over, laughing hysterically.

Never happened to me, either. Nope.

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.

Have you ever noticed a truly good foul up is almost always
accomplished with an appreciative audience?

One also rapidly ;earns not to go target shooting on a totally
windless day. Waiting an hour to be able to see the target again gets
old fast. Smokeless powder? We don't need no steenking smokeless powder.

NO--I have a lath--Steif & Bruin 11X22--melt down old 45-70 hulls for stock.

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.
