Hardening Parts

[Triggersmith]

I've always been a staunch Uberti fan.  Recently I acquired a Pietta 58 Remington.  It is my habit to dismantle a new gun and check for burrs etc.  Every gun I have bought has had  a burr or distortion on the tip of the hand. On my Uberti 1860 this burr caused me a timing problem on my R&D cylinder. The Pietta had the same burr.  From building muzzleloaders I learned to harden some of the lock parts using Kasenite.  It is my contention that hardening the tip of the hand could mostly eliminate the distortion of the hand.  Has anyone done this?
Would the hardened tip of the hand against the hardened surface of the cylinder cause a problem? There may be other parts that could use the same hardening treatment.  I sure could use some feedback on this.  BTW the machine work on the Pietta was as good as any of my Ubertis.

Triggersmith,

You might be able to case harden the hand but one theory is the hand is left soft so as not to wear the notches on the cylinder. I simply cleaned up the burrs on mine, checked the timing and left it go at that. YMMV.

Thanks Bull,
It's the old something has to give.  Better the in-expensive hand than the kind of expensive cylinder. I cleaned up the burr and now when you cock it you hear "rem-ing-ton.  Music to my ears. I appreciate your reply
