Thank you for the LOL Dave - Austin. Your bionic leg kick was well worth multiple rewinds. Thanks!!
He he..
I thought he was doing the river dance. 😂😂
I'm concerned for the knee joint after seeing that.
99% planning, 1% excitement and validation of your preparation ! I like the way that bucket quickly sorts the material.
Yes, the sieve bucket is the best.
@@demolitiondavedrillandblast Best operator I have seen on your channel I reckon! Neat and tidy and fast
For Sure Murray.
First 👍's up demolition Dave the most explosive man on TH-cam thank you for sharing
Thanks for watching Scott.
Thanks for the video. The bionic man sound effect was a nice touch
I am, like yourself, not a young man anymore. The difference between you and me, you still work like a young man. You handle that hammer quite well. And they way to use your leg to add body weight behind the bit, just amazing. 3 minutes on that beast and I would be just a heap of biological splat on the ground. Well done sir. A testament to men of our generation. You are one hard ass dude! 👍
Thanks for watching and contributing Alan, I guess that If I had been doing an office job all my working life and I just picked up a rock drill for the first time it would be wiped out, it comes down to what you are used to and muscle development from repeated use.
Hi Dave,
You have a lot of really good videos, especially the un-covered work. Even so, this is still one of my favorites.
I like your time-bending on drilling, loading, and then geo-disassembly.
Thank you !!
Hey, thanks for watching and contributing Dave.
That leg-swing at 4:25 caught me entirely off-guard. I love it.
Yeah no kidding. You miss and you're singing soprano.
I think I might have said it before, but you'd make one hell of a good rock climber. With your light weight and amazing flexibility, plus you must be strong as heck from lifting those big drills all day. You'd also be able to identify any rock face you were about to climb. Seeing you almost leap into the air, like an acrobat, lifting your leg over the drill @4:20 is what made me think it again today. You are like a wee stick of dynamite!
Thanks Trevor, I probably would be good at rock climbing, as a kid I would climb everything including light poles and power poles, steel and wood types.
@@demolitiondavedrillandblast I really liked the "special effects" you added to your leap onto the drill. You really are the 6 million dollar man 😊.
Dave does not climb rocks, he brings them down to himself.
@@SuperRede4u Yeah, I caught The Six Million Dollar Man Special Effects music!
We are showing are age, that show was on TV in the late 70s and early 80s. 😂
Great job Dave ... it was fun to see the drills competing!....also I agree with the other guy about the bionic leg moment... that had me going! 😂
He he... It comes from my ballet practice.... not really.
Haha 😄
Man that leg kick on the drill makes you "The Rock Ninja".
I like that Jerry, it's got a bit of a ring to it.
Thank you Dave . That new drill really cuts the hardest granite fast..😊
It sure does Mark.
It warms the cockles of my heart to see someone on TH-cam wearing PPE
Yes, good idea if you want to work near stone dust and live. Shocks me what I see on TH-cam from India, very sad.
Great video Dave what a way to finish a Friday night. 👍👍
Thanks for tuning in Bob.
Great fun Dave, thank you for sharing your process and the interesting-but-not-startling results.
If it gets too startling the neighbors start complaining Jim.
Dave you consistently put out great video along with some excellent music. Thank you very much
Thanks #44
Love the "magic wand" work when you are covering. Point and like magic the cover appears!
That reminds me that I have to buy another long one this weekend.
Those slo-mos give my 15" 1200W PSB Subsonic 7 subwoofer a REAL workout. Excellent video. Thanks for sharing!
I bet it does, lots of low frequencies in there that most people miss out on. Thanks for watching, don't forget to hit the like and subscribe.
Great stuff! Love seeing the blasting! Very well planned and thought through before drilling and blasting.
Thanks for tuning in Penelope, please get comfortable and enjoy the view ~ 250 blast videos to chose from
Dave you don't stop impressing me with your work and your eye for detail. Until you come again stay safe and keep blowing things up 😂😂😂😂😂
Thanks Lee. I will not be stopping any time soon.
Good gravy man, biggest rocks I’ve ever seen in a building site!
Oh... this is nothing Thomas!
im really impressed by how u take the time to explain the steps and show the viwer the steps to it all.
I find that is important and really helpful information because blasting is one of those trades u don't hear ppl talk about alot or how its done especially where i em its like fort nox in trying to find or get information on anything. So its really cool watching someone like yourself that is whilling to thank you for that
You are welcome Aaron.
You accomplish more in one day than my entire family accomplishes in a lifetime
You guys must be very laid back.
some awesome shots dave thank you for sharing!
Thanks for tuning in CT.
Hey Dave, you’ve done it again, spectacularly!!!! Bravo 👍👍👍
Thanks Swishy.
G'day Dave nice job mate
Thanks Murphy.
another entertaining video Dave.thanks for sharing it with us.
Thanks for watching it Bruce, please share it with others.
Hi Dave, Glad to see you again! My brain cells have missed the boom booms! Hopefully you'll be back soon! Glad to see the re-builds did good! Your silver bullet is a beast! Take Care, Stay safe! Jim
The Silver Bullet @$350 was probably the best money that I have ever spent on equipment, drilled tens of thousands of holes for me and put me ahead of the pack when the other guys were using fairy size drills.
Tossed that 200 kilo granite chip like a football! Cheers Dave glad we're beficiaries of some success in your field of expertise!
Lot of energy available in this stuff JW, thanks for tuning in again.
What an air machine, in the UK the same machine was run at 30Psi and very efective at diging through tarmac.
Great video. Thanks for sharing.
👍👍👍👍👍THUMBS UP👍👍👍👍👍
Thanks for tuning in!
It's always good to know who's paying and especially that they can and will ! 👍🙃
You really have to keep on top of this when you work for your self.
Such a pleasure seeing you mate. Its been too long since i been over. Hopefully soon
Fantastic work Dave 👍👍
Thanks Luke.
Hello from the Rockies. Thanks for the video
Blasters paradise.
Another great video Demolition Dave .
Thanks for watching William
Looks like hard work for an old guy on his toes! Impressing mate!
It is hard work!
Thank you Dave for very nice and informative videos
Hey, thanks for watching and contributing #56
Great blasting as always DD.
Thanks TC
Howdy from Sacramento! Looks like some nice dirt there after all those pesky rocks are cleared. Always amazed at how controlled your booms are. Thanks for sharing!
Thanks for watching KP, the soil cover does and excellent job of covering the violence.
I’m in Rocklin. Do you know where this is?…
@Mike Gowan I know Rocklin yes. But Dave works down in Australia...
at 4:20, you killed me with the Steve Austin leg raise lol
Apart from all the drilling, looks like a lot of fun!
It is.
Fantastic job Dave! I can see why you like Old Silver so much mate it’s a beauty 👍🏻
It is. static.wikia.nocookie.net/tractors/images/5/5a/Holmans_drill_1955.jpg/revision/latest?cb=20110419190441
Great stuff.. thx for posting.
Thank you for watching and contributing #101
Dave great video and bangers!!!
Thanks Bill.
Harvesting ripe boulders is hard work, but very satisfying.
Yes, a lot harder than digging up potatoes... but also a lot more fun.
@@demolitiondavedrillandblast That's enough harvest to make a lot of stone soup.
You guys do excellent work. Thank you for the videos.
Great video, really interesting.
Thanks for watching CJ
Who needs to visit the gym, when your Demo Dave - don't know how you manage all the physical stuff! New drill seems pretty good, plus the usual ''leg over'' :). I remember that long term use of these percussion drills can produce De Quervains disease (tenosynovitis) from sustained vibration - hope you have seemingly managed to stay away from that.
That's a big (huge) assortment of rocks - more great work. That 72 hole final one showed the delays nicely on slo-mo. You mention the 'echelon' element - back when I studied this stuff we called it 'Chevron" pattern - same idea - this was way back in UK.
Hi Chris, thanks for tuning in, I certainly don't need to go to the gym... but I do swim a lot. I don't have any broken body issues at this stage but I would like to give the hand drill jobs away soon and just do drill rig stuff. The chevron pattern hook up is an old classic that looks similar but but has some big differences, e.g. Shot started at delay #0 in the center of the face, delay #1 was 3 holes that made the first chevron, delay #2 was 5 holes that made the second chevron etc. This is a big advantage over the earlier method of firing it row after row as it gave better fragmentation. These days the plan is to make sure that no 2 holes fire with a time delay closer than 8 milliseconds - a critical number for blast vibration management considerations. This is achieved by using a control row (front row) time spacing of 17ms/hole and the reverse echelon rows are timed @ 42ms/hole, this works out very nicely without any sub 8ms timing collisions until you get about 5 or 6 rows deep and give superior fragmentation compared to previous methods.
Many thanks for the reply Dave - appreciated. I see the difference now - my 'chevron' training was of course rock face work - quarry etc - sort of 'classic'. Your considerations make total sense and I imagine the planning for your delays must be pretty carefully made to avoid 'collisions'! Some similarities between approaches in as much as one always wants a hole energy to go where it can do most useful work Thanks again :)
The Aussie Ian Anderson on Paddy’s Motorbike.
What an explosive combination.
An ex Sapper from Scotland who loved blowing stuff up.
Ian Anderson.... of Jethro Tull fame? Thanks for watching.
@@demolitiondavedrillandblast Indeed it is Dave 😉
As an ex Sapper who loved a bit of improvised demolition and is a machine operator by trade your videos tick all of the boxes.
Looking forward to more 👍🏼
Ps love the controlled blast method btw.
Genius.
What depth of cover are you looking at minimum around 0.3m ?
My favorite part of this video was teh side by side drilling comparison. (I have the CP-69 too) It would be great if you could do more of this type of very informative product testing/reviews. Thanks!
Yeah, I could do a video comparing the various drill head types, e.g. Integral chisel / Cross bit / Button bit and the efficiencies of knock on taper rods against Rope thread rods. Also thinking about knocking up a really simple venturi powered dust extraction system (like I once used) with the hope that some of the Indian drillers might pick up on the idea and save their lungs. Any other ideas? Oh... by the way, your YT channel has been up for more than a year now and I still don't see any video!
I love the high speed video. makes you look like a busy orange ant.
No, I really work that fast!
You can tell it’s Australia. Bloody love Australia, such a beautiful place to go. 💯🫶🏻👍
Thanks and welcome back to TH-cam, I like al of your HV stuff, for some time now I have been thinking about building a European wasp killer using about 20KV using an old TV line output transformer. I have a professional electronic background.
Clever title…and a good watch, cheers Dave.
Thanks Bob.
Great job !
Thanks Jammer.
and love the tune during the drill-off! 👍👍👊👊
Music from the TH-cam royalty free library - A call is upon us by the 126's
Dave is the Six Million Dollar Man, YES! Retired and lookin' good. I knew blue jeans were a clue.
... I hope you've been well and were able to catch the aurora.
Thanks #42, all good here thanks, lot of solar flares this week also but no big CME impacts to cause Aurora again at my latitude.
Great job. Have a wonder day.
Thanks Brent... ahh... drilled 8 hours today and I'm a bit brokem
Nice, Dave. Glad you’re happy with the new drill but geez you must be exhausted at the end of the day 😅 What a site, hope someone budgeted for the rock! Thanks for the video.
I have no trouble getting to sleep.
thanks for another vid mate 👍
No problem, thanks for watching and contributing Jason.
Dave, the way you fling your leg over the drill handle you could pass for ballet guy. Just saying. LOL. Thanks for the video
Maybe I should hire so Ballerinas for assistance.
@@demolitiondavedrillandblast Would it be more cost effective to hire big, fat , corn fed ballerinas ??? AHH. My buddy thinks the advertising for your big ballerinas might be a problem... To get really effective workers .........You yourself sure do well..........
Over weight workers tire out very quickly.
Hey Joe, I can not answer your emails because the return address bounces every time. do you have another email address that I can try??
it took me a while to figure out what was so familiar about that excavator bucket. it’s like a massive cat litter scoop lmao
I think the rockpile over at the edge of the hole is sufficient testament to the amount of rock removed. It must have been good hard rock- looked like it fractured and popped apart in a predictable and consistent way. Beautiful execution, Dave!
It was really hard granite MLP, thanks for watching.
Impressive and highly skilled.
Thanks John and thanks for watching.
The sound effects had me laughing!
Thanks for noticing Dave.
First time viewer, love watching a true pro at work. Hoping you have an apprentice learning from your experience
Thanks Martin, I have helped a few people learn the ways but they move on because it is too difficult for most people.
The sound effects! :D
Great video
Thanks for tuning in.
Would love to see the calculations for the perfect amount of dirt. But I didn't see a calculator. I saw a guy with a stick pointing. I'm impressed.
The stick is calibrated.
I'm impressed as usual at your video craftsmanship and your layout and efficient technique for loading and tying up the blasts. It was fun watching that longer segment of you setting up that one blast. Being as how I used to tunnel blast I was of course comparing the similarities and the absolute differences required for blasting on surface around people's houses.
You peaked my interest about the nature of Kangaroos as well and what it must be like living and or working in their vicinity. I think everyone has seen the videos of not aware people being mugged by big male reds but those types of portrayals I would image tend to not be the norm. It would be like bear and cougar videos here.
Speaking of tend, this video is a 10 Dave. Thanks for producing them and putting them up for us to watch.
Thanks for tuning in, good to have people onboard that have worked in the industry. The Grey Kangaroos are generally not much of a problem as they would rather get out of your way...most of the time but you don't push them as they can be very dangerous. We do not have the Reds around here but I understand they are best left alone. Biggest problem with the greys is that they have no road sense at all and regularly tangle with traffic.
@@demolitiondavedrillandblast We have deer that do that (No car sense). The carnage on the road is incredible. Thanks for responding.
Who needs yoga for flexibility when you could just have a day on the drill. Regards from Scotland.
4:30 Jeez mate that's a job for the young apprentice surely lol.
Great video.
Sounds like a good idea but the ipod generation can't keep up.
Thank you so much for your content! You are an artist! And you get to use boom goo!
Boom goo... Hmmm...is that the same stuff as blasting snot?
good job old fella
I'm loving the 'roos!
There is heaps of them in this area, so many that they are a pest.
@@demolitiondavedrillandblast I'm certain you cannot use blasting substances to remove those 'roos, but how did you chase so many off? Does the siren scare 'em away? Thanks for these brilliant TH-cam Videos, Demo Dave!
The are keen on letting people get close and they will usually just take off, the drone really freaks them out!
looking at the job on the front end i'd been tempted to bring in the drill rig Dave! seems like the digger operator knew how to use the rock bucket pretty good especially compared to a few you've had in the past!
I would have bought my little excavator mounted drill to this one except that my tilt tray truck is off the road at the moment, my other option is to pay somebody to move it for me but I would not be able to take it home each day.
Having had Two machines stolen, I'm not keen on leaving stuff at the site.
@@demolitiondavedrillandblast yeah thieves are bad around here too most who do work like that and leave the machine there will pull something vital and take that with them so it won't start!
@@demolitiondavedrillandblast you know Dave after thinking on it i bet that vibration issue at a 100 psi is an out of balance piston! steel can be denser in some parts of stock than others if the mill that poured it isn't careful! i bet if it's spin balanced it'll show it's heavier on one side!
There has also been a failed attempt to steel my little digger, they were unable to start it because I had pulled the plug off the engine stop solinoid.... so they gave the instrument panel a hammer massage.
Never thought of that, I could try another piston nest time it's in bits.
Love the Steve Austin Sound effect at 4:20
I just tossed that in at the last moment Woody, seems like it hit the spot. Thanks for tuning in, please like and subscribe.
Howdy demolition Dave
Hi there!
Excellent as usual Dave.
Thanks Vaughn.
Apart from the length & kick retainer issue, the CP69 seems to be up there with your trusty Silver Bullet.
Yes it was money well spent, hope it lasts as long as the Silver Bullet. Should do, CP is good stuff, even though they are now made in India, I have had a good run so far with Indian drills.
,,TAKE THAT, TOUGH ROCK...LOL...NICE JOB, KEEP SAFE AND WELL..
It makes sense but I had no idea you’d cover the stone with earth before blasting. Do you cut them in such way that you can just backhoe all of it out of the way together?
What's that you say Skippy, "Dave is making big rocks smaller, again" and "Timmy is in the well again and he can jolly well stay there"
I used to love that show as a little kid.
@@demolitiondavedrillandblast 👍
I think a video where you show the blasting hardware and fuses and delays, and how it is all wired up would be awesome. Also can you reuse anything for a subsequent blast? Thanks mate, appreciate your work in making these videos.
Thanks for watching Murray, my videos are deliberately light on with these details.
@Demolition Dave Drilling and Blasting yeah I guess I didn't think it through haha. Cheers for the reply mate 👍
Kinda proprietary formula and artistry that part there. Also proportioning proper amounts of the "working materials" per hole and based on depth as well as the material to be broken is based on hard knowledge and decades of experience. Understanding the way rocks break and move and sequencing the delays to accommodate the material split off and moving just looks easy in the videos. Likely for Dave it is in fact just that, easy. There is actually allot of info on the internet about the how and why of everything Dave does and Dave not telling helps keep his insurance low!
Amazing as always!
The CP69 ... I know nothing about drills, but they look symmetrically built ... could a person not unbolt the bottom end and turn it 180 degrees to relocate the foot plate release?
Thanks for sharing 🇨🇦
That has crossed my mind Paul, some drills you can however with this one it has a small built in oil reservoir for chuck lubrication and I expect that a oil gallery runs between the main body and lower bit. I'll know the first time I have to open it up.
Using those drill constantly must have some effect on your body in the long term. I enjoy your videos. Stay safe.
Just abject curiosity (I have no idea how I ended up here, but this was a great watch...very fascinating) but what are all the PVC pipes sticking out of the ground?
Some plumber decided that it would a good idea to install all of the under slab plumbing before the rock was removed.
Interesting that the det. chord flashes but is not destroyed, cool. Like to see a close of the det. det. chord.
That is because it is not det cord, it is plastic signal tube.
@@demolitiondavedrillandblast Very cool tech , thanks.
A few spots of rain and short stuff is out of there. You do not want to get wet, or you might shrink. Maybe you should move out of Victoria into some sunshine. We have plenty in the central west of NSW and I am told they have lots of it in QLD.
I am so over the rain David...
when the excavator is picking out the rubble you can be seen going in picking something out as its uncovered. What are you cleaning out and is it hazardous or just picking up trash?
Picking up all of the used surface delay clips and signal tube, trash.
Are you collecting the waste fuses to make clean fill. My local quarry runs them thur the crusher , makes colourful driveways
Yes, don't want these leaving the site as it can cause problems when they end up at show and tell.
Great video, always enjoy, what are the grey tubes sticking out above grade?
Somebody thought it would be a good idea to install all of the under slab plumbing before the rocks were removed
@@demolitiondavedrillandblast what, not a good idea
id be getting the ground plumbing rechecked, the ground movement and shockwaves, will have changed angles, flow rakes and may have even cracked piping, however, blasting has always fascinated me, is it something thats hard to get into? and by hard i mean cost and education/ cert time?
It will be checked James, It's not easy to get into and build a business around, in hindsight just about anything else would have been easier. Probably the biggest barrier to start up these days is that everybody wants to see that you have insurance and a good deal of experience. Problem #1 you just can not get insurance with out at least 10 years experience and you don't get many jobs with out it. Problem #2 unless you are blasting most days there is no way you can afford the outrageous cost of the insurance. There are easier ways to make a good living.
Great job Dave! What are you retrieving when you go in while the crane is digging up the dirt after the explosion?
I'm picking up all of the used plastic signal tube.
@@demolitiondavedrillandblast , i expect it is not for reuse, just to alleviate any fears of unexploded ordinance.
@vsv nrg - Causes problems when kids take it to school for show and tell.
@@demolitiondavedrillandblast , i can relate to that. when i was in primary school i was removed from a class. i couldnt work out what i'd done. then the senior teacher explained to me that my little brother had found dad's .22 ammo and brought a box of it to school for show and tell.
Wish I had some of that stone for my landscaping.
Hiya Dave,
A great video, thank you. Where you kept nipping in and out, were you removing the blast lines?
Do you still get butterflies on shot day?
Stay safe, Steve.
Just the used plastic signal tube and surface delay clips
I worked in blasting for a good while some job work like what you are doing here but mostly quarry and coal mine above and below ground I was a driver I hauled powder and I would also help loads shots I have to say I've worked with a lot of blasters in 30 years but I can tell by your job site attention to detail you are one of the best at what you do job is clean tidy and I like how tidy your surface delays are laid out there is not a bunch of loose stimming all over the place very nice work I miss doing this for a living I'm a diabetic now and had to give up driving but I have a lot of great memories I do have one question though every blaster I ever knew was superstitious and had a ritual before a shot something they always did do you have one and if you do can I asked what it is I always found that interesting for some reason It's ok if you dont want to say and even more interesting if you don't have one Thanks from a old mining comrade in the US cheers
Thanks Elwood, I have learned that keeping the hook up neat and bundling the excess tube helps a lot when you are carefully uncovering a missfire and trying to work out where if failed. No rituals here, just "heads up everbody"... BOOOOOOM! Please like and subscribe if you are new here.
@@demolitiondavedrillandblast Yeah notice quick siren pop it and done here the coal mines and quarry its normally 3 longs horns or sirens and Fire in the whole and fire Its funny I had to move a blaster shooter one time and he damn near lost his mind he made me fire the shot which didnt bother me as I help him load it and knew for the most part what it was going to do I told him after that he was a good blaster and that he should let the superstitious that others passed on to him rule his mind that if you do it by the numbers it will be fine but that sometimes no matter what you do it just goes south its just the way it goes thanks for response have a great day cheers
Great work Steve Austin!
Thanks #14
What are those flashes of light above the dirt pile as the explosives are triggered? With everything covered so deep, I didn't expect to see anything like that.
The flashes are the pieces of plastic signal tube lighting up, there is one coming out from the detonator on the end of each row of holes and these set up to confirm that the shot has progressed all of the way to the end without any problems.
Had no idea you Ausies had to do such battle with rock. Seems to have the most stubborn rocks on earth.
It is not that bad Jason, the rock is only in a few areas, most of Aus. is easy digging.
Hey Dave, Just curious here, But when you are drilling the holes how do you determine the depth of the hole to put the charge in ? Is it by feel or just guessing or what? Really enjoyed this video, Great work. Thanks for sharing.
I would normally drill just a bit past the depth that I need to break.
I live in an area where bedrock is tens of metres below the surface cover so watching you blast these is fascinating. Is the rock you are blasting discrete boulders or is it bedrock material? If they are boulders I wonder what was big enough to deposit huge boulders like these?
These rocks are not glacial deposits, this is where it pushed through the ground from deep below, the surface rocks are boulders the weathered away from the bedrock below.
