New cylinder,,teeth to long?

(1/2) > >>

willy:
Converting a Uberti to 44 special,,Bought new cylinder and it will not fit in frame ,, tried fitting it in a Uberti cattleman revolver and a new El patron revolver,, It was a no go on both,,After measuring everything ,,the only thing different is the ratchet teeth are longer on the new cylinder,,So before I start taking a file to it,,Is this a feasible solution?

Does this cylinder have a removable bushing ??

Yes, you can work the star down, but advised, you may well screw up the headspace in the process.

Yes it does have the removable bushing,,The teeth on the new cylinder are .01 longer than the old cylinder,,all other measurements are the same,,Also the teeth on new cylinder come to a sharp point where as the original cylinder has more of a blunt shape on the teeth.

Pettifogger:
If the bushing is removable remove it and try putting the cylinder in the frame.  If it goes in put an empty case in the cylinder and check the headspace.  Then put the cylinder in a lathe and turn the teeth down until the headspace is correct.  Then fit the cylinder bushing.  I had several brand new Colt cylinders that came just as you describe and had to turn the ratchet teeth down to set the headspace.  If you donot know how to set headspace let someone else fit the cylinder.  I also would not use a file if you genuinely have to remove .01 of material.  That is 100 thousands of an inch and the chances of you filing the teeth square is pretty low.

Hey Larsen, your calculator needs a new battery  :)
.01 is 10 thousandths.
