pietta 1851 timing ?

I removed the barrel on my Pietta Remington 58 when reaming the chambers and used the chamfer kit then. I will need to check and see if it will have clearance to work in the mounted barrel. Mike D.

I tried the set out last night in the 58 and there is enough clearance between the top strap and the angle cutters, brass laps and chamfer tool but not the flat end barrel cutters pictured.
I have some more lapping to do as I discovered mine is still a bit snug under the barrel threads when I was checking the top strap clearance for you last night.
I fire lapped this barrel but can see it did not get all the choke constriction out under the threads where it goes through the frame.
This is another very common problem with production guns and does nothing good for accuracy.
The brass alignment bushing has a snug slip fit from muzzle down to just ahead of the forcing cone and then stops up solid.
I will thoroughly clean the area and make sure lead accumulation is not giving me a false reading before hand lapping the barrel. Mike D.

Removing a Remmy barrel is not as scary as it sounds.
Clamp the barrel flats in a soft-jawed vise and insert a 2X2 hunk of wood around 2ft long into the frame opening. It helps to apply heat and on occasion penetrant (such as AeroKroil) for the stubborn ones. It's important to chuck the barrel as close to the frame as you can in the vise jaws. Once you break it free it simply unscrews.

I've seen it done that way with revolvers but in the Gunsmithing school program I went through it was highly frowned upon as you can wreck a frame with such a practice under certain conditions.
It is far better to make a simple flat bar wrench which keeps the frame from the possibility torque bending the cylinder window. Do this and the frame is shot! Mike D.
