Imagine cranking this thing with half a ton of boom sticks on the other end, with no way of knowing when its gonna pop. Jack in the box from hell, the anticipation alone would kill me.
Reasons why the US/UK didn't use this for anything besides engineering purposes or disposing of explosives. You'd normally be pretty far away if you're using this old thing. The better ones were smaller and used a windup plunger method and actually fit in a demo mans satchel. Only issue is they require silver chloride fuses.
The meter may not have been able to catch the actual peak voltage. It would have been able to catch it rising slowly on the capacitors though. Some of these units put out up to 1000V peak when they trigger.
bigclivedotcom love seeing when my two favorite channels watch each other. Pure quality and unadulterated fun from both. Y'all need to do a collaboration
There once was a girl from Kahrue Found an elephant's twang in her stew Said the waiter, "Don't shout, and don't wave it about!" "For the others will all want one too!"
nozmoking1 there once was a girlie named Jill, that used a dynamite stick for a thrill. they found her vagina in south Carolina and bits of her tits in Brazil.
When I was a young apprenticed sparky my boss would use a hand-cranked 500 volt Megger (low current) insulation & continuity tester to shock me at every opportunity. He thought this was a great laugh until the rainy day he returned from a trip to the van to our place of work with wet hands and placed one hand on the door latch and the other on the key. Unbeknownst to him, I had connected said Megger poles to the inside of both the latch and key and was cranking the tester as fast as it could go when he attempted to open the door. From outside there was a cry and the sound of an armful of electrical components falling to the ground, followed by much laughter on my part. Needless to say, I was never 'Meggered' again after that day. Good days, now sadly long ago!
Oooooohhhhh you need to get one of them old WW2 military crank phones. My 5th grade teacher had one. He used to line us up holding hands and see how many of us he could shock at once. Record was 31 btw.
Yes, they do have a bit of bite. Rally interesting to watch is the guy running wire holding both ends of the wire and you give it a twist, then a scream is heard, me and Dan look at each other and in unison Good Circuit
In a weekend in warrior type of event, we played around with army field phones. Just like this thing, it has a crank to fire pixies down the line to ring the bell at the other end. Or "tickle" a Private told to, "Hold these two wires and whatever happens don't drop them!" Didn't take too much cranking to get the yelling to happen.
Accept the perfect handle screwdriver into your life! I'm trying to find a place semi-nearby where I can get 500-1000 of those drop forged for a reasonable price.
I’m a blaster myself and if you want to get rid of this wonderful machine, I would trade you a newer model for it! A plastiiic fantastique batteria operated 10 caps wonder! For the record, a 12v car battery will usually fail to detonate multiple blastic caps in one circuit... You need a higher voltage in order to innitiate multiple electric caps... Mind you, I have used a car battery, a compressor battery as well as a handheld radio battery to initiate a single cap on non-electric blasts! But the best emergency method is to connect multiple 9v batteries (they snap together!) and get a higher voltage...
good sir, you shure as hell just made my day... that old blasters limerick was something told to me a long time ago and stuck with me ever since... thank you brother, so ever much
If the contact on relay was held in and the generator cranked what do you think the output voltage would be? Would it still peak at 200ish? Or if you disabled the relay from "automatically" switching on can the capacitors produce a bigger bang if you cranked it and then manually engaged the relay contacts?
I have one of these I picked up at a local Sally-Anne thrift store, The lady at the cash asked me what it was for, I new it was for blowing shit up I began to tell her but realized I did not want to tell her anything that might stop me from being able to buy it so I told her "I though it was for setting off fireworks, and just seemed interesting". Mine is in somewhat nicer exterior condition but the same inside I opened it up to just have a peek. I didn't put my meter on it because I wasn't sure about what it put out and didn't want to blow anything up, but It did blow up the bulb in my 12V continuity test light with a good pop.
Kind of reminds me of those old phone ringer magnetos. They give you a good zap, many will do 100v ac. Folks use them for fishing and gathering earthworms!
In electronics class back in the day we would goof off with camera flash charging boards (remember disposable cameras.) They were a self contained capacitor, charger and battery. Pretty fun probably not around any more. Also in college I remember building a device to charge a capacitor using a 555, transistor and a transformer hooked up in reverse. Good times.
All my videos that venture into blasting get demonetized. But hey even if I do a video with no swearing or anything wrong it's still demonetized. CZcams never tell you where the problem lies. I dare say that beautiful machine is built to shoot 50 caps in series. The blasting mother you want is the Beethoven Mk 7 Exploder. That baby's got a killer sting. Condenser style exploders don't like parallel circuits. Their impulse is too quick to excite the circuit when the bridgewires are stacked up in parallel. Anyway it's a job for some. Obviously CZcams is in RIP mode. Killed by PewDiePie
After reading some of the comments, I remember many moons ago, when I was a young lad, taking Autobody in High School circa 1969, The shop teacher wanted to demonstrate how volatile acetylene is/was, so he got out a balloon, filled it up to approx. 4-6" in Dia. Then, using a Oxygen / Acetylene torch, to set it off, the out come was much worse then he thought it would be. He wound up with black soot on his face, and his eyeglass's were left ajar on his face. We ALL LAUGHED like no tomorrow. P.S. It should be noted he was a volunteer fireman. First word out of his mouth was WOW!!!! I didn't think it would be that big of an explosion .
Maxx B - Speaking of...he used solid core wire. I read that stranded was "much" better because the DC current, flowing on the surface of the wire, was more efficient because there's more total surface area vs. solid. (skin effect). Now _I already know_ it's irrelevant for what he's actually doing here (f*cking around). I just thought about it and wondered if anyone else heard/learned/read the same thing.
Skin effect from eddy currents is really only an issue with high frequency AC. The caps discharge DC voltage, so either would work fine assuming proper size. Solid core could be preferable for commercial blasting due to it being cheaper. Stranded would have the advantage of not suffering bend radius related work hardening. Thus, the wire used for military purposes, such as claymore wire, is stranded despite being more costly.
@AvE drops "the astute war weary and grizzled veteran campaigners amongst us instantly recognize that despite the patina of chicken shit this did not come out of a mine on account of it not being completely fuckerd", into casual conversation like I'd say "it could be worse". Dude, I bow to your superior gift for turn of phrase and pithy idiom. There are folks on TV making 8 figures who lack the talent to generate as much humor in a year that you can whip up in 11:02. Well played sir!
It's fun to blow up Christmas lights with those old electric blasting machines. Especially if you heat the tip of the bulb with a lighter, then dip in ice water. Flick the end off the bulb and put some fine FFFF black powder in. Add some fine aluminum shavings for more boom!
We used to make the bridge wires for home made dets from resistors, fired with the guts of a disposable camera flash circuit. Those were the days you could play around with such things and not end up wearing an orange jumpsuit.
7:40 I love how he leaves this sort of stuff in. Most YTers would do that to extend the playtime of their video... but AvE does it to show us that even the most seasoned veterans make silly mistakes sometimes. I just love the fact that he shows us that he's a faulty human, just like the rest of us.
My guess is that the generator is AC (like the telephone generators), rectified, and charges up the 2 big caps, when they reach a voltage, the neon fires the small capacitor is also discharged into the relay (holds the relay on long enough), which discharges the big ones Note the bigger gear on the 'handle', so the generator would be going much faster. You could have connected your meter directly to the caps.
I agree ... the neon lamp is connected in series with the relay coil and the small cap goes across the lamp and other terminal of the coil . Cranking the (brushed) generator produces a voltage that charges the all capacitors but the one across the lamp/coil combination charges more slowly (series resistor ?) , this allows the two big caps to fully charge before the small cap reaches about 60 volts to fire the neon lamp (on dc) and dump the small cap into the relay coil thus pulling in the armature and dumping the big caps into the blasting wire terminals . In 1960 , the rectifiers (if used) most likely would have been the selenium type and very noticeable ... they also have a funky (and poisonous) aroma .
I'd say the neon bulb is used as a voltage latch. They tend to conduct around 90V. So when you turn the crank, both caps get charged from the dynamo. The smaller one is in series with the relay coil, with the neon bulb in the way. When the small cap reaches a high enough voltage, the neon bulb closes the circuit, energizes the relay and the big caps get dumped to the output and ... boom.
Sitting here in my shed in England on a Friday afternoon with a cold one and my laptop is a great time to watch your latest video, being as I'm retired (the missus says that should read 'retarded'). And I wasn't disappointed, as soon as you picked up your jeweller's hammer I knew I was in for a treat with those magical words "tappy tap tap"... I wish you had a live streeming web cam in your shop, I could listen to you all day, it takes me back to my working days, best days of my life. Keep the videos coming pal!
A good way to protect those plastic screens from getting all dickered up is clear packaging tape. If it gets scratched, or covered in shmoo you can peel it off and slap a new piece on good as new.
Ingenious how this works: generator charges big capacitors and little capacitor. Little capacitor has a neon bulb with a break-over (conduction) voltage of ~60 -120V (works like a HV Zener diode) connected to relay coil; relay discharges large caps to dynamite. Boom. This system is a minimum voltage level auto switch, when you crank enough to charge up the big caps enough, the relay switches them to the dynamite. No batteries or power supply needed! P.S. Gears are not "reduction". The ratio of the Large Gear to the small gear on the dynamo speeds up the RPMs on the generator to produce higher voltage (simple generator = higher RPM = Higher Voltage). DC or AC? Solid or stranded wire? The "skin effect" is better for high frequencies, so stranded wire would be better. Why? The real issue is Dv / Dt (Delta Voltage vs Delta Time), essentially the fast change of the voltage (from the discharge of the Caps). The fast voltage change is equivalent to a high frequency, and would benefit from the "skin effect" (rise time in microseconds, can be seen on an oscilloscope).
Waited my whole life to see this! I might have guessed it was just a dynamo. Looks like a good job for an analog meter or your storage scope, put some kind of load resistor on the output and see what you got! I'm guessing the people who make blasting caps would tell you what it takes to reliably fire them? Another thing that surprised me was the lack of something like "SAFE/ARM" switch, something to short the output while you're getting it all organized. My question: Does the relay do that automatically? That is, when the machine is idle, are those terminals shorted together?
Seems to me that the neon bulb is in series with the relay coil acting like a super simple treshold detector - when the capacitors reach a voltage higher than ~185V (neon bulb striking voltage) it energizes the relay and closes the contacts, finaly dumping current into the blasting caps.
You'd have fun with an old 50 cap machine. Just a big dynamo, and a plain copper switch at the base that closes the circuit when the handle is fully depressed.
That dynamo has a gear multiplication, not a reduction. It actually looks a lot like an old telephone ringer from the early days. Those things had a nice bite to them if you ever grabbed it.
If you wanted you could polish the display of your Fruke with some toothpaste to get some of the scratches out, it works with acrylic watch crystals to de-jankify them.
Imagine cranking this thing with half a ton of boom sticks on the other end, with no way of knowing when its gonna pop. Jack in the box from hell, the anticipation alone would kill me.
Reasons why the US/UK didn't use this for anything besides engineering purposes or disposing of explosives. You'd normally be pretty far away if you're using this old thing. The better ones were smaller and used a windup plunger method and actually fit in a demo mans satchel. Only issue is they require silver chloride fuses.
It should really play "pop goes the weasel" as you crank it.
The meter may not have been able to catch the actual peak voltage. It would have been able to catch it rising slowly on the capacitors though. Some of these units put out up to 1000V peak when they trigger.

Powerful enough to be used as a spot welder for that metal strip thing on a 18650 battery?
My guess is that the generator is AC (like the telephone generators), rectified, and charges up the 2 big caps, when they reach a voltage, the neon fires the small capacitor is also discharged into the relay (holds the relay on long enough), which discharges the big ones
Note the bigger gear on the 'handle', so the generator would be going much faster.
You could have connected your meter directly to the caps.
I agree ... the neon lamp is connected in series with the relay coil and the small cap goes across the lamp and other terminal of the coil . Cranking the (brushed) generator produces a voltage that charges the all capacitors but the one across the lamp/coil combination charges more slowly (series resistor ?) , this allows the two big caps to fully charge before the small cap reaches about 60 volts to fire the neon lamp (on dc) and dump the small cap into the relay coil thus pulling in the armature and dumping the big caps into the blasting wire terminals .
In 1960 , the rectifiers (if used) most likely would have been the selenium type and very noticeable ... they also have a funky (and poisonous) aroma .
Reminiscent of the capacitor discharge ignition for gas turbine engines, sans motorb. Neat!
Nice, Think it said on the side "Magneto" so they'll be the type of little generator used . Like the ignition on classic engines.
great video thank you where in the great north do you find this stuff ?
That's cool!! Do you know at what level the volts/amps has to be at before the sets of the charge?
I had a hand held C4 detonator once. Never used it or took it apart but I thought I was pretty cool
Did the plastic insulating sheets get replaced before you buttoned up that beauty?
Love your stuff...learn something and have a good laugh.
I'd say the neon bulb is used as a voltage latch. They tend to conduct around 90V. So when you turn the crank, both caps get charged from the dynamo. The smaller one is in series with the relay coil, with the neon bulb in the way. When the small cap reaches a high enough voltage, the neon bulb closes the circuit, energizes the relay and the big caps get dumped to the output and ... boom.
That last bit at the end with the resistors proves that we're all still 8 years old on the inside.

What happened to all the old tools anyways? I mean they were built to last, yet I rarely see them around. Just people didn't take car of them?
Waited my whole life to see this! I might have guessed it was just a dynamo. Looks like a good job for an analog meter or your storage scope, put some kind of load resistor on the output and see what you got! I'm guessing the people who make blasting caps would tell you what it takes to reliably fire them? Another thing that surprised me was the lack of something like "SAFE/ARM" switch, something to short the output while you're getting it all organized. My question: Does the relay do that automatically? That is, when the machine is idle, are those terminals shorted together?
is it ok to use stainless steel fasteners in an aluminum casting without it stripping? I've only heard of it being done with heli-coils.
Seems to me that the neon bulb is in series with the relay coil acting like a super simple treshold detector - when the capacitors reach a voltage higher than ~185V (neon bulb striking voltage) it energizes the relay and closes the contacts, finaly dumping current into the blasting caps.
That into gets a thumbs up alone!
You'd have fun with an old 50 cap machine. Just a big dynamo, and a plain copper switch at the base that closes the circuit when the handle is fully depressed.
That dynamo has a gear multiplication, not a reduction. It actually looks a lot like an old telephone ringer from the early days. Those things had a nice bite to them if you ever grabbed it.
Ok, this has to be the first time I have seen someone sentence a resistor to death before. Good job.
If you wanted you could polish the display of your Fruke with some toothpaste to get some of the scratches out, it works with acrylic watch crystals to de-jankify them.
i love that last line your the best
For fox creek i dam near soiled my shorts from laughing so hard. Thank you Uncle bumblefuck for lighting up my boring evening.
