I agree, a lot of home modifications can be done IF one takes his time and works slowly. My basement machine shop is pretty minimal by today's standards, yet not terrible considering what was around in 1870. Exactly the sort of comment I was hoping to hear. That one is long gone to the crusher, we now need a ministerial permit to hold any cartridge handgun over 38 cal unless its a proper capgun - so I have a nice pigeon pair of stepped cylinder capguns - 1851 navy in 44 (yeah I know no such thing originally but I like the modern version) and a pocket navy 38.
Pre ww2 nutall lathe and a chinese drill press at the time (many moons ago)Ĭentre bored and turned the blank in the lathe, marked it out by hand and drilled the holes using the drill press, made a chamber reamer from an old hand tap by grinding to shape on the lathe (didnt have the skill required to heat treat a reamer) reamed it on the drill press - marked the locking notches through the bolt hole with the cylinder assembled and a locator rod down the barrel, cut the notches by eye using the drill press and a small woodruff key slot cutter. Might surprise you what you can do if you think your way through it Since there's no CNC machine in my basement making cylinders is bit more biting off than I can chew even though "buyin" has never been nearly as much fun for me as "buildin". Whoa Indian Joe - "make a new cylinder"?. I have one of these and its stayin just the way it is - it might get a pettifogger workover one day - but not a conversion. Trade it off for one in 32 and convert that ? That little colt would make a dead cool 22 - but too easy and you could buy a ruger bearcat for half the cost. If you make a new cylinder rather than bore out the old one - most of these capguns you can squeeze an extra twenty thou or so of cylinder wall - take a little out of the frame - tighten the tolerances up - you be surprised what can be doneĭid a remmy once to 44/40 and found enough extra cylinder diameter that I ended up stepping the barrel threads 50 thou to get it back in line I know these conversions were done for black powder cartridges, but I wonder if there were safety issues with some of these conversions, especially those done on the small frame models.256008 The rear portion of the cylinder wall looks dangerously thin to me. I found this photo of what looks like a Mason-Richards, Colt factory conversion of a Pocket Navy. I know there's lots of machine shop talent on this forum so I guess I posted my original comment to see if anyone ever attempted a conversion like this.
