Cesare Posted June 14, 2017 Report Share Posted June 14, 2017 So I have just on impulse bought a Denix Sharps 1863 carbine. Thinking about a way to convert it into AS. The basic idea is to take use Brocock shell cartridge w air pressure or co2. The biggest challenge will probably be to make a firing pin strike the small primer. Easiest way to make the firing mechanism is probably to prolong the hammer with a screw and file down the firing block so it may tip back and forth a few mm more and attaching a firing pin on the right place. The bore is about .45-48 cal thinking of installing a Brocock round in a .45-70govt cartridge which should be a drop in fit. Link to post Share on other sites
harborne blue Posted June 14, 2017 Report Share Posted June 14, 2017 What you could also try is a merger between the Dan Wesson shells. In fact, if you have access to the machinery it would not be the most insane idea to hack up a DW revolver and see if you can squeeze it into the Sharps body. BTW I've now had to add one of these to shopping list, even if it's just a prop alongside the Schofield. My credit card does not thank you :-( Link to post Share on other sites
druid799 Posted June 14, 2017 Report Share Posted June 14, 2017 VERY much Looking forward to your finished product my friend , very much indeed ! Link to post Share on other sites
Kalashnikov_kid Posted June 21, 2017 Report Share Posted June 21, 2017 IIRC the original sharps use a paper cartridge with separate percussion cap. It wasn't until the 1870's ones that they went to 45-70 metallic cartridges. How about adding a breach seal to the face of the breach block and having the internals from a TM nbb in there (centimeter master or similar) . You could place the valve in such a way that it vents into a small port drilled into the side of the barrel near the breach (behind the BB). That way you could thumb load individual rounds into the gun my 2c Link to post Share on other sites
Cesare Posted June 23, 2017 Author Report Share Posted June 23, 2017 It sounds like a really good plan except that I am missing the parts and it is a larger project. Ordered some 45-70govt cartridges but they were out so have to re-order them now Link to post Share on other sites
harborne blue Posted June 29, 2017 Report Share Posted June 29, 2017 Just a thought - have you thought about boring out the breech to take gas shotty shells? Might be easier than Brocock - at least you'll have loads of spare parts available! Link to post Share on other sites
Cesare Posted June 29, 2017 Author Report Share Posted June 29, 2017 Yes but I would also have a shotgun instead of a rifle... it might be a plan-b Right now I am working on a inner barrel system that would line up with the cartridge. Probably the precision will be awful but I am just glad if it fires : ) Also thinking about making it a 8mm instead of 6mm Link to post Share on other sites
Kalashnikov_kid Posted June 29, 2017 Report Share Posted June 29, 2017 8mm for the win! Seamless hydraulic pipe is a good source for 8mm barrels Link to post Share on other sites
renegadecow Posted June 29, 2017 Report Share Posted June 29, 2017 Right now I am working on a inner barrel system that would line up with the cartridge. Probably the precision will be awful but I am just glad if it fires : ) Being fairly familiar with cartridge firing revolvers, what makes or breaks its potential for accuracy is the quality of the o-ring holding the bb and the concentricity of the shell to the forcing cone. If the o-rings are bad (has cast lines) and the shells aren't generally uniform (like Win Gun rubber tips) the o-ring acts like a hop rubber or the bb is forced to roll against one edge of the barrel (like a sideways LRB) giving actual hop up direction a life of its own.

My gun-fu won't extend to a rifle but I am thinking of a gas shell shottie... Link to post Share on other sites
