Thanks for tuning in 525 there is about 245 rock breaking videos on this channel, most of my work is with explosives www.youtube.com/@demolitiondavedrillandblast/videos

[@TechGorilla1987]

I love seeing explosives deployed as much as the next guy, but this video shows off skills that were used as far back as ancient times and they are every bit as relevant and useful today. Great job, mate.

I have been told that it was the Egyptians that came up with this idea.

[@deconteesawyer5758]

It wasn't till modern day that a fellow said "I think I'll build my house on top of that huge outcrop of rock because it will be so much easier to to remove the rock crawling around on hands and knees afterward."

[@MrOlgrumpy]

@@demolitiondavedrillandblast Did the Egyptians have steel feathers and wedges,? maybe wooden plugs soaked in water,but I'm damned if I know how they bored the holes with the metals they had,Wasn;t it Aliens ?? 🙃🙃

[@gth042]

@@MrOlgrumpy Not taking anything away from those guys, but their rock is/was cake by comparison. Once a dent/hole gets started it's "just" a matter of working the dust into a paste and working it. True bamboo chopsticks from one's favorite carry-out will put up a good fight when twisted into a rock with a tad of water. When the rock is more like concrete, all the "easier". I think it's more of a toughness vs hardness plus a little water and a lot of time. Alien intervention, however, cuts out a lot of slaves and lets the whole process fit into a youtube clip.

For some reason I wasn’t notified about this video so on Friday, March 10, 2023. I finally found it. I sell hydraulic hoses and some of them instead of being crimped are swaged. There is enormous friction when that happens. We use STP oil treatment designed to be used in engines usually ones that are worn after many years of use. We try various kinds of grease and lubricants recommended by the manufacturer of the fittings, but I can tell you, STP is as good, if not better than anything we’ve ever used, including the lubricants recommended by the manufacture of the fittings, and the tooling to install them. The viscosity is heavy, it doesn’t run easy, and probably in your case could be brushed on. I am not sure it’s available in your country, but chances are, it is.

[@demolitiondavedrillandblast]

Well that is interesting, yes we have STP here, I used it once a long time ago to quiet down an old Datsun 180B engine, it worked well. I'll get some and give it a try YT.

Hi Dave, Many thanks for the great videos as always. I have had to break out rock in the past on jobs. I have used "Cheepo" HT Engine grease. The Thick type. Works a treat. Just out of interest I went and checked the prices of some of the more exotic goo for this job. Over US$ 600.oo a liter.......They are mad! I am not going to pay for some Bodger's mistress as well for this stuff. Titanium Dioxide powder is inexpensive. Its used in paint etc. It just thickens up the grease. And is neutral chemically. All that the surfaces need to do is just slide past each other, and not bind. When you see that Porsche wizz by your Ute!! Well then...........Someone who has not been price checking has paid for it. All the best for the New Year from us out here in Darkest Africa. Cheers Mate. David.

Ivory Bar soap, makes a great pressure resistant lubricant and quite cheap. I have never used it to split stone but I have used it when I worked for a local house mover. We would use it to lubricate the metal beams when sliding the house onto their trailer wheel segments. If it can withstand the weight of a several hundred tonne home, I would think it would also work for lubricating plugs/feathers while splitting stone. If you look up the info on grease tech, most all of them use soap as a thickening and lubricant agent anyway. The only difference with your grease is they've added in the metal. Thought I would pass this along in case you want to give it a shot.

[@bobbaer869]

Wow you worked hard on that job. 🍺🍺🍺

[@demolitiondavedrillandblast]

Yeah, and again today... day off to recover tomorrow.

[@looneylenny87]

Oh yeah, I remember that feeling when the split sounded. Makes me want to go out and break stone, again

[@demolitiondavedrillandblast]

Just do it.

[@jwaterous224]

Thanks for shouldering these boulders Dave! For anyone asking if the stone really makes that sqeaky sound when being uprooted it sure does! I've seen at least a couple You Tubers using battery powered grease guns on heavy equipment and was wondering if the tubes of grease they use might be available in the titanium dioxide variety? Packaging is everything these days and the tubes could be easier to manufacture than the cans so mabey less money than cans?

[@demolitiondavedrillandblast]

Oh, I would love one of those grease guns, I have ruined several of the regular type... but have you seen the price of them?? Have not seen similar grease in cartridges.

[@Tiger351]

Wow that's some expensive grease if it's $240 for a 1kg? tin, those 35 mm plugs and feathers are holding up pretty well given you said they were only a cheap set. It's always satisfying hearing that crack when the rock lets go using the plugs and feathers, maybe more so than the bang of explosives.

[@demolitiondavedrillandblast]

They are holding up well, a customer gave them to me when he worked out that they were not going to break a 2m rock. They were starting to get mushroomed on top so I re ground them over the break.

[@robertsewell3063]

Dave - first video of yours I've watched. Bloody hard work, that rock. Do you know what sort of rock it is?

[@demolitiondavedrillandblast]

Thanks for tuning in Robert, the rock is Ferny Creek Rhyodacite really hard high density stuff.

[@rgmolpus]

Some days, you'd be happy to hire the Incredible Hulk as a helper.....

[@demolitiondavedrillandblast]

The really big guys just don't have the endurance Richard.

[@GARDENER42]

Happy new year Dave.

[@demolitiondavedrillandblast]

Thanks #42 it's off to a flying start.

[@jethrodigger]

Love your work as usual Dave. Did you have those feather and wedges made or is there someone who sells them .?

[@demolitiondavedrillandblast]

Thanks for watching Jethro, plugs and feathers were all purchased. The big ones came from Brunner and Lay, the smaller ones were bought on line from China.

[@jethrodigger]

@@demolitiondavedrillandblast thanks dave ill look them up.
