Time to the tale of my makeshft matchlock I tested today, I reckon.
>>29425905
Do continue
>>29425905
I might be slow, since I am trying to crop and convert some videos of the shoot to webm
Anyways, what we have here is a peice of copper pipe JB welded onto 1m of stainless steel schedule 80 .5" pipe to make a flash pan. The touchhole is 1/16", and that is a 2.5" bolt screwed into one end that I got threaded.
>>29425946
Specs on the pipe. Also, the internet says its bursting pressure is 26,250 PSI, which should be more than double 100 grain black powder + .50 calibre round ball, which is what I used.
>>29425985
Now, this is a shitty as all shit picture, but this is welded seam pipe. But as the previous pictures says, it still meets ASME SA312, ASTM A312, which means even though it is welded, it still has the same burst pressure as stated before, 26,250 PSI
>>29426017
The tools used to load the pipe. I did rough math and guesstimated 1/8 teaspoon of FFG black powder = 10 grain.
I tested twice with 50 grain, thrice with 100 grain, and once with 150 grain.
I'm lurking keep going
Very interested.
>>29426081
>>29426094
Sorry for the delay, I have video of me firing it, but I cannot get the crop tool to work to crop me out of it.
Anyways, since everything else was nigger rigged, here is my new 80$ vice which was on sale for 40$
>>29426135
Well shit, my video editing software is fucking garbage, so no video, just pics.
>>29426194
Well, the previous picture is out of order.
Because here is a homemade fuse in the flash pan with 50 grain in the barrel and 10 grain in the pan.
>>29426212
Fuck I am getting mixed up.
First go wasn't recorded, it was 50 grain in the barrel and 10 in the pan. Everything went hunky dory.
Second time, with 100 in the barrel and 10 in the pan, blew the pan off.
>>29426231
Here's the pic after the 50 grain go. Everything was all nice and well.
>>29426261
Amazingly, one of them actually hit the target, since the vice wasn't properly secured to the picnic table and rocked back forth left right while firing.
The only other things I have to share are two videos I am uploading to youtube. One is me poking the touchhole with a sparkler because the flashpan was gone to fire it. The second is a panoramic view of the firing.
But it'll take 20-30 minutes to upload them because my internet is boonie tier.
>>29426319
So, to sum up:
1) The pipe withstood 1x 150 grain shot and several 100 grain shots without obvious deformation or critical pipe bombery.
2) I can unscrew the bolt for easy cleaning.
3) I need to find a better way to attach a flash pan.
4) Now that I know the barrel shouldn't fail and blow my face off, I can go about carving up a stock for it.
5) These are individual tests, by one guy who figured that math was on his side. It appears that it was and still is. I do not garuntee similar results for others, and you'll be putting your safety at risk just like I did.
6) Videos are uploading, wait out.
7) I'll probaly check back in when the stock is done for a should firing test, but that won't be until June or July I reckon.
>>29426351
I'd never considered #2. Very clever
>>29426351
i personally would weld the bolt on so it doesnt have the slightest chance of flying into your eye.
very cool man, can't wait to see the videos
>>29426382
I tried to find the PSI with regards to screw threading, but that was some math I couldn't find. I just figured 2 inches of thread should hold maybe. If anybody is a proper scientician and knows how to calculate that, it would be much appreciated.
>>29426351
you need to weld or at least soder the flashpan onto the pipe
If you have a propane torch this can be done shittily with a coat hanger
Here's the bolt. None of the threads, in the pipe or on the bolt, seem chipped or broken.
Correction to my last.
>>29426430
I science that I wouldn't put that thing anywhere near my face while firing.
>>29426443
>using Nesquik for a breech
Brilliant.

>>29425905
Oh nice you came back
>>29426430
so the funny thing is that most breech plugs are threaded, but also supported in the stock. the best example of this is the flange coming off of the breech plug screwed into and recessed into the stock of the gun.
look at the designs of flintlock/percussion guns as an example.
as long as you don't overcharge or obstruct the barrel it should be fine.
but you should definitely retain the plug in a stock or rock or something
>>29426513
Anyways, a short video of me using a sparkler to set it off after flash pan disappeared. I looked around and found the clothes pins, but couldn't find the pan.
https://www.youtube.com/watch?v=14qkROhcZKM&feature=youtu.be
And a stupidly long video of the whole thing in action because the sparkler took 30 seconds to light. Skipped to 40 seconds in, and please don't try to dox.

>>29426539
that's real fuckin neato
>>29426430
But it is okay when Thompson does it.
https://www.youtube.com/watch?v=-s5i6jN1F6k
No offence but it's really shit
Take out the pan and make it a percussion cap musket so you don't have to mess around when reloading and worry about the powder being blown into your face
Well done, seems unlikely to explode in the user's direction. 9/10
>>29426629
I live in Canada and percussion requires a PAL.
I have a PAL, but I don't want to muck around with legalities. A matchlock rifle considered a non firearm (unless used in the commission of a crime), does not require paperwork, and since I building it myself, I am not obligated to go through the hassle of getting an FRT to protect myself from the RCMP.
>>29425946
>that JB weld
>>29426861
When you don't know knots, use lots.
>>29426844
Make a sleeve to fit around it if your soldering skills are not up to it. Also a cover would help a lot in preventing accidents/ keeping it in the pan when important.
Regarding the PAL, you would make a percussion TUBE design to work around it. https://www.youtube.com/watch?v=v_Iyl-Tnjgo
Or a pinfire design http://britishmilitariaforums.yuku.com/topic/3051/its-all-getting-too-much-i-need-more-gun-safes-12-pinfire
>>29425905
In the UK, your makeshift matchlock would require the same license as a normal hunting shotgun.
>>29426861
it's almost as good as a real weld, and you don't even have to put your beer down.
>>29426893
1) I ain't fucking around with pinfire
2) It is probably for the best the pan blew off. I was underdesigned, it did need shielding and a cover.
3) Percussion tube looks just as annoying as pinfire.
>>29426441
I'm no professional welder or anything but I've never heard of welding copper to stainless steel.
Also if you're using a torch and a coat hanger, thats more like brasing since it's non fusion bonding. The torch and coat hanger is a backyard way to do it
>>29427028
420 Braze it.
>>29426906
That's why we are better off making machine guns, if you are going to get caught you might as well get caught making something good and take a few rozzers with you
>>29427338
I say, have you read Utopia by Thomas More?
I was gonna say you're stupid and gonna blow yourself up, but then I noticed you're using seamless stainless
Carry on
>>29425905
>>29427835
>seamless stainless
but there is a seam
>>29428147
My bad
Didn't see it in the pics
OPs gonna blow himself up
>>29428183
But he didn't
>>29428214
Needs more powder
>>29428243
that would be a pipe bomb
>>29427028
it would be brazing yes, its why i included sodering, Ideally he would weld it, and you can with some sticks and a car battery but the torch and coat hanger is a bit cheaper/expedient.
From his picture it looks like hes overcharging the pan, and it should definitely be thicker.
>>29428648
>overcharging the pan
how much powder should be in the pan?
Not OP but I'm toying with the idea of making an electronically fired black powder musket once I start welding class so this post is relevant to my plans
>>29428693
the further the flashhole is from the base of the pan the more powder you will need, im not sure if your hole is centered or at an angle relative to the barrel. the larger the gradient away from the main charge the larger the amount of powder you will need.
its about probability as opposed to exact amounts, if this was a pistol id tell you to use about an eighth of the charge but im not to sure how that would translate to a rifle.
This kind of wishy washy is why people keep saying you should use caps. but youre already ahead by actually going out and doing it
>>29428825
The pan before it was blown off was angled so ....I cannot explain using words, see mspain drawing. Red Line represents matchhole
My first few tries were 10 grains, but then I started using significantly less, just dusting the hole with powder (because the pan was blown off)
>>29428726
>electronically fired
Tell me more
>>29428726
>>29429431
piezoelectric ignition anons.
>>29429415
make your pan out of a flat sheet of 3/8" thick steel and use a dremel to grind a pan into it, then wire weld it to the barrel. also you can easily add a pan cover to that as compared to your copper bowl which is apparently kablooeying due to the backblast out of the touchhole.
>>29429583
I was actually going to slice open a t joint, shimmy it down the barrel so the T is above the touch hole, and affix it with a hose clamp on either side.
>>29429583
>piezoelectric ignition
You're going to make a lock rifle whose trigger is identical to that of a BBQ lighter?
...I like it.
>>29429415
thats how it should be gj mate, you should work your way up from 3-5 grains find the lowest possible then go a couple over.
Ideally you weld the flashpan to the barrel, alternatively make a plywood body and support it and the breech plug. Youll have less to worry about the pan breaking off.
>>29429583
this guys idea makes more sense
>>29429633
drill two holes in the "pan" and have a removable copper pipe cap to cover it with. put a BBQ piezo through one hole and a steel pin through the other. let the spark it creates light the powder. It will be easier to clean than having a piezo go into the chamber.
but srs weld a steel pan with a pan cover to the side. make a dieselpunk matchlock with a resistance heater (think car lighter element) on the end of the serpentine attached to a 9v battery in the stock.
>>29429771
>matchlock with a resistance heater (think car lighter element) on the end of the serpentine attached to a 9v battery in the stock.
Goddamn, I like the way you think. An on/off electric match would be awesome.
Got my notice that this finally shipped. should be here by the 31st
https://www.gunpartscorp.com/ad/587360.htm
going to buy a piece of 1" section 5 stainless pipe for a receiver and pop it in my friends lathe to thread and make a breech plug. It'll either end up with a wire stock or looking like a filipino guerrilla shotgun
Seen things like this made before,
As others have said, soldering or brazing should be perfectly fine if you get a good fitup.
Also, Canadian with a PAL can build firearms no problem. you just need to follow registration laws and guidelines for restricted firearms. Call the CFP, they'll say the same thing.

Would be a bear to keep it firing because of the amount of stuff that will end up on the heating element though.
