lost wax process is neater'n a peter

just have a shallow pan of the goop, deep enough to a cover half of the depth of whatever steel part you want to copy. Let the goop harden around your part. Remove the part, flip it over, repeat on the other side. Shave down the 2 "halves" of your goop-mould, until they are the correct "depth" to reproduce the part, (as evidenced by measuring the wax reproduction of your steel part) Then you submerge your wax part in a slurry of ceramic mix. Let it dry, do it again, then you drill a drain hole thru the ceramic and fire it in an oven. the melted wax will drain out, and then you'll have a ceramic mould, into which you can pour molten steel (or aluminum if you can't get the temps required for steel). break off the ceramic, and there's an exact copy of your original steel part. It'll have little flashings that have to be ground off, and some things can't be cast. You can't cast a hole or narrow slot, for instance. So minor machining might still be required. But this technique saves you tremendous amounts of machining. It's become so well refined that you can cast big coil springs, like for RR cars. They of course still require heat treating to become springs.

this is the way to create a DA version of cap and ball. Guess which revolver wifey will copy and which caliber?

Wouldn't it be simpler to just buy a replica DA in black powder? I know Pietta made a Starr replica, and there's likely to be copies of the Tranter, even a LeMat if a person didn't mind the bulk and silly-high cost. Probably others as well that I don't know about, I'm not up on black powder stuff.

the idea is having something that you can put real charges thru, without damage and without paying an arm and a leg. I intend to see this become commercially available. It will be a modern revolver. Just wont have the side swing cylinder. nipples will be threaded in from the front of the chamber, using a 2 diameter chamber and a flange on the nipple, so as to create strength. The idea is a pair of tubular bullets in each chamber. 40 grs each, at 2000 fps.. That should tell you caliber, which should tell you the gun, One in each hand means you've got the equivalent of a Mak 11 380. Yet they can be sold thru the mail, to anyone. $600 each, stainless steel, using Hodgdon Triple 7.

those old timey DA's were pos's.

no way to try it until got the wife. :-) somebody has to be free to buy the initial DA revolver. Weld up the crane, weld the new nipple bodies into the rear of each chamber, develope the load, take the proven concept to numerous retailers, like Bass Pro, redhead, cabella's, get prices and numbers they'll pay for, take those promises to the current maker, and see what can be done. Most makers will re-tool for something special, if they are paid in full for 1000 units (distributor cost) IF they only have to shift around their current offerings. Like put kit gun sights on a chief's .38, for instance. Distributor cost on 1000 units runs about half of current retail. So, say the current pistol retails at $400. need 200k of committments from the retailers. However, this set up requires considerably more than just the shifting of some parts/processes. So probably need each of 5 retailers to cough up 80k, meaning price of end product would have to be $600. But it would be so popular that you could get more. My cut would be half of the next 1000 are MINE, to be sold mail order. :-)

WOW! What a fantastic idea!




Who could have devised this get rich scheme involving BPS, Cabalas an the gun makers? Can see them laughing now. Another thing do you have product liability insurance on this stuff in case someone would buy such a thing an get hurt or worse? Asked about that before but no answer.
And BTY the small J frames do have adjustable sights. It is called the Model 60

I know you talked about it probably 5-8 years ago, but 30 years?

Wouldn't you need a patent first? There are DA black powder guns already on the market, but most people buy replica of SA's for the re-enactment and black powder shoots. Garand might know more about this. I can't see a big market for a non-replica DA revolver. Black Powder SA revolvers will start getting cranky after only 12 to 18 rounds due to black powder residue. My BP Colt replica is fun to shoot, a really pain to clean after only 3 to 4 cylinders fired even with Pyrodex.
