Got my hand on a brand new rockdrill from 1989. Testing it and breaking rock by using wedges and explosives. Pionjar / Pionjär 120 English Subtitle available
"89 was my last year underground gold mining. We had jacklegs. the unit was much smaller because the compressor wasn't incorporated. A side compressor producing 120psi via 1" hose was used. I wanted to purchase one several years after the mine shut down because the uses for these machines are everywhere. Technically, you could have drilled those 3 holes in less than 10 minutes with much less effort. It's a glorified jack hammar. I ran one of those in another mine in solid granite. By the way, water as a lubricant & coolant will make your carbide bits last longer & drill faster.
I would suggest using vibration absorbing gloves all the time, when using the Poinjar. I melted my favourite jacket on the exhaust of my snowblower just a few days ago. LOVED the shots of the blast, both forwards and in reverse. I really like when you explain what you're doing. Some people may appreciate if you explain why, also.
Good job. My old man bought one of those in the early 1960s in the US. I spent many days operating it as a jackhammer, well point driver, and a rock drill. I was young and strong but, it beat me pretty bad each day. I used a 12# stone breaking sledge to score the line that I wanted to split before drillin the holes. My brother inherited it and in the 1980s was able to get a rebuilding kit so that it worked like new. I think that he still has it. Good Luck, Rick
That was back when these machines were first introduced by Atlas Copco. However this wasn't the first machine of its kind- that would most likely be the Syntron gas hammer which was developed for the US Army back in the mid 1940s. There was also the Barco free-piston gasoline hammer introduced sometime in the 1920s which had a separate box which contained a buzz coil and battery connected with a cable resembling a large air hose. It was started by pushing a plunger on top which forced the piston down.
@@douro20 I was an Army Combat Engineer in the 1970s. All we had was the big air compressor with a lot of tools for it(drills, chain saws, and tampers).
Getting a headache from handling dynamite without gloves is completely normal. As you know, dynamite is essentially nitroglycerin that enters your body through your skin. Nitroglycerin dilates your blood vessels, including the meninges. The irritation of the meninges is the headache you feel. In addition, due to the dilated blood vessels, there may be a significant drop in blood pressure, which can lead to dizziness or fainting. It is a normal reaction to the ingestion of nitroglycerin into your body and just like in the medical use case of nitroglycerin: the combination of Viagra and nitroglycerin in your body can kill you.
I used one of them back in the 80's had a dirt bit to loosen the dirt and then used it as a jack hammer breaking rock for a footer!, we had the wedges to split rock. We also had a mix that looked like epoxy we poured it in the holes and it split the rock overnight!. Its a neat outfit, love to get another one!.
Nice work with both the wedges and the dynamite. I also had to use both when digging water pipes to my house. And for drilling I used - what else than an ex-Swedish Army Pionjär 😉 All the best for your projects and cheers from Finland!
One very important thing I took away from watching this video was the dynamite. It was mentioned it can cause headaches if handled bare handed. But more importantly was the fact that headaches come from low blood pressure. My wife and son both get migraines so bad they will actually throw up from the pain. I will look into the correlation in more detail. Thank you for mentioning this.
@@hibahprice6887 it's not worth going to the doctor due to headaches from handling dynamite, it's a well understood physiological mechanism. Headaches doe not come from low blood pressure, headaches come from irritation of the meninges. Nitroglycerin rapidly dilates your blood vessels, including the meninges. This rapid dilation irritates the meninges, that is the headache you feel. You can perfectly live with constant low blood pressure without getting headaches. It's the rapid change. As all of you know, dynamite is ~75% nitroglycerin and it will absorb through your skin.
Came across your RU-vid channel and glad I did. Enjoy the content and subscribed. Began watching all your videos from the first one. Thanks for the entertainment.
Another excellent video.....there's only one way this channel is going...looking forward to seeing the crusher in action and your plans for the 2023..... Happy New Year to you when it comes around.....🏴
Oh man, did it have that old-school industrial tool smell? Bit of varied greases combined with the paint and the wooden box = you can't bottle that, but if you could you'd be rich. *Nice.*
I like this machine!!! And what I like even more is that after 34 years of storage, there is no trace of rust on it and it is completely functional and ready for use. This is an excellent testimony to the Swedish army and its thrift.
G'day mate. I was watching with great intent and all of a sudden there was this magnificent river in the foreground and I completely lost my concentration on your drill and started thinking about the trout fishing at your back door. That drill certainly makes it easy to split the rocks even with the wedges but you can't beat those big fire crackers. Good for rocks, stumps, fishing, I didn't say that. The play back's look awesome.
Its actually impressive that dinamite in sweden is that cheap. In croatia that one stick would cost about 100-150 euros. Plus you cant buy it without certificate for handling with dinamite. Im sure that you have one beacuse you cant buy dinamite without cerification
1kg dynamite 4€!? I wonder why a pack of crackers (ridiculous 20g black powder, 20 pieces) cost around 5€ here in Germany... Your videos are quite good and complex. Greetings from Berlin.
If people wanting to pay why take less? But not use them as fire crackers if you don't know exaktly what you are doing! You need too get tmem really high up whit pressured air or simular and a real safe ignition devise maybe triggered by altitude so there can't be any danger for the innocent!!! The army got some cool old ammonition they could use at such eventions...
excellent work 🙂🙃I especially enjoyed the reverse explosion in slow-mo 😄that drill could use a handle to stand on to get some additional vertical downward force 🥵cheers from Australia
Thanks! Yeah that was cool, i been thinking about making some kind of attachment to the excavator for holding the drill in the future! Cheers from Sweden!
Excelente trabajo, y muy impresionantes las imágenes de las explosiones, sobre todo las repeticiones en cámara lenta. Me resulta sorprendente que al usar el taladro no uses algún tipo de refrigeración, ya que toda esa fricción tiene que generar mucho calor. Un saludo.
That drill looks like it would be perfect mounted on the end of somthing mechanical! Where on earth does a person casually come across dynamite? I always thought you needed to have all sorts of expensive licences etc Loving the videos, could you do one outlining your land/workshop please
Casually come across. Is the key phrase. You don’t, at least in the usa. It is a high explosive, without training, and license. You don’t get to play with it. It is not a toy. He must have had training, military? He knows how to use it. He respects it. 👍👍👍👍👍👍👍👍👍👍👍👍
Good video - thanks for sharing your work. You really should wear a dust mask whilst drilling rocks - inhaling the rock dust will eventually cause you health problems otherwise.
Awesome! Lol....those wedge and feathers are demolition size. ' RU-vidr 'Demolition Dave' has several blasting videos posted. The last time I used that particular explosive was in 1981. It's more highly regulated in the USA now.
Thanks! Never used a wedge before, worked fine though. I actually learned the leg thing 17:56 after watching @demolitiondavedrillandblast videos!. 1981 was a few years ago..
I had 100 Acres maybe 15 min north of town here .. a LOT of barefaced granite. I planned to buy a engine driven rock drill like this! .. for fencing purposes.
Hose flies are the worst, luckily I've never been bitten. Looks like they are as plentiful there as they are in the Northeast of the US and Canada. I've been living in the Pacific Northwest for the past few years and haven't seen any. The mosquito population is also very low here. Maybe pointless info, but that's how it goes!
I started building road around 1986,have never used electric caps. Non E much safer .works the same just no electricity to worry about radios static,ect.
Snyggt jobbat, jag är också ute efter något liknande så jag kan spräcka sten på guldfältena i Finland, tack för du delade med dig, kommer följa din kanal🤠💪
We’ve got deer flies In Ontario, same or very similar to those you have. These insects are a plague, they are the absolute worst things for going in the woods from mid to late summer. We call them horse flies or Deer flies, and they are abundant in areas where deer congregate. Horse/deer flies will ruin any working or any outing, and many roadways are unusable by foot in summer. I think they are attracted to the extra carbon dioxide created by your breath when you work outside in summer.
The Egyptians, don’t have nothing on your rock skills!! LoL, jk, I’m a commercial electrician, we have a similar drill, only ours has attachments so it can double as a tamper. It’s definitely a workout to use, especially when it keeps getting stuck in the rock.
If you could have undercut a trench under the lower rock, and placed the explosives in between the two rocks, what might have happened?.you would have to contain the blast
Perhaps the addition of a vacuum where the drill bit enters the rock might capture the silica dust. I understand silica is rather harmful in your lungs.
Demolition Dave Drilling and Blasting would be wondering where you got the Brand new antique drill from. I have just come across your channel and have started watching. Thanks
@@M.BJOERNSTROEM Hi! I have 4 of these drills, one that I bought for a job where we had to carry everything in and 3 more because they were nearly new and very cheap.
I'm so jealous of you and your rock drill. The northeastern USA is FILLED with glacial boulders. I would love to break and to remove the boulders from my property.
