Yes.. I picked one up off the EE. try and find paper roll caps anywhere. they don`t seem to exist any more in Canada.

Anyway, made a bunch of double layer aluminum caps. I`d post pics but at work and didn`t take any. I grabbed a pack of cheap red plastic ring caps and scraped out the mixture that is in those. 80 red caps worth does not make a big pile of the stuff, and if you try it, don`t scrape directly over the container you are keeping the powder in. it flashes with a "woof" and your wife asks you what you are burning, you see spots while you try to put out burning bits of paper from the little red caps...... don`t ask how I know.
so last night I mixed the powder with rubbing alcohol and used a flat toothpick to drop a tiny dollop if the now gooey powder into the caps. work it into the corners of the cap.
I added .5 of a scoop (made from a small pistol primer ) of black powder and capped the lot off with a newsprint paper disk, punched out with the hole punch that comes with the Tap-o-cap, tamped down while wet with the little dowel that comes with the Tap-o- cap.
only have a very small amount of BP handy when tamping, you can imagine what may happen if one went off while tamping in a pile of loose BP. I had no such incident.

now the key part. people have reported using hairspray to lock everything together. that's ok if you are VERY gentle with them.

I used some of the wife`s hairspray WAX. ( don`t tell her)
its stickyish and stays sticky for a while. let these little things dry overnight.

anyway, I made six caps(no I did not use all the mixture, probably enough left for 20 more, maybe.) they all made a very satisfying BANG when tested this morning before work. first strike each time. I was very happy.
do this outside, wives tend not to like the smell of rotten eggs in the morning...

conclusion- while not a particularly expedient way to get caps for your percussion guns, if you like to tinker like me, its quite enjoyable. if you don`t have caps, can`t get any or SHTF, or whatever, one of these in the old toolbox won`t hurt. all I seem to be able to find is No10 caps which only the heavy mainspring sidelocks will set off first strike because they don`t sit properly on the nipples used.. my little CVA squirrel needs two strikes, but not always.

anyone know of a paper roll cap source in Canada?
 
I'd just order some priming compound, about $20US for around 2000 caps worth.

I think you can order roll caps on line as well but the bulk powder would save a bunch of work.

When I was a kid, back in the 60s, I made pinfire cartridges from CIL BB Cap cases using caps punched out of the rolls under a blunted 1/16" nail. A tiny charge of BP would send a wax bullet across the basement in a puff of smoke. One thing I did notice in my various experiments with paper caps is that they were quite corrosive.

I had a toy derringer that used caps to propel a soft rubber bullet. Trying to boost power with extra caps worked only up to a point, one cap too many would cushion the hammer blow and nothing would happen.

Logan's book on underhammer guns quoted an old time recipe for making chlorate based pills for pill lock guns. I would imagine that these would be as corrosive as paper caps.
 
i`m liking that priming compound. might have to order some of that for the shft box.
at least i know that i can do it with toy cap compound, and toy caps will work as percussion caps as well, but in no way do they stop the hammer or nipple from being damaged. i`d definitely only do it again in an emergency. strike anywhere match heads work as well, but not as reliably in my tests. and it flashes much easier when crushing it.
nice work yomomma, i think i remember you mentioning that a while ago in another post. my lathe is still under construction. one day i`ll get it finished and make a musket cap sized Tap-O-cap.

I have one of those Tap-O-Caps as well; I wonder if one tin cap over a toy cap would work?? Just because it would sure speed up cap-making... I'm gonna have to try that. Have a trail walk coming up in May, would be fun to see if home brew caps will work for the day.
