In the past we made the 1st gas gun at 100K subs, and the 2nd at 200k. But when you put a chainsaw impact together and it works, you don't just let it gather dust in the corner until some number is hit. Enjoy!
if you want some custom parts made, hit me up, i can cook something up, like custom hammers and anvils, main drawback would be shipping them from europe

Ah... Brings me back to the early days of electric Nerf blaster modding. Seeing six blocks of Chinesium IMR cells daisy-chained to put mains voltage through a plastic machine gun and spit darts at 750RPM bacj in 2009 was certainly something.
Great video, you guys are the Dr. Nefario of the Impact testing youtube community, over 40 years ago i built farm equipment in the late 70's early 80's and when we put the tractor frames together we used a 1 1/4 or 1 1/2" drive gun to install the frame bolts to the axles and double nutted each one and this was to the tune of just under 1300 ft lbs , we switched off each time and the gun was mounted on a custom dolly and had wheels that flipped up pneumatically and dowel pins that went down into the concrete floor, we had to wear customized hearing protection while performing our work, just shy of 129 DB's and were only allowed a week on and a week off, putting the tires on the axles was a cake walk compared to doing the frame, wheel torque was a tiny 500 ft lbs , love the builds , just replacing the spring in that gun could bring, my guess another 10% extra torque, we'll leave that up to you 2 Dr. Nefarios ,👍 I'll stick with my Makita mid torque it does everything i need and i have a large 3/4" drive for heavier stuff
Sure...you could have asked for 300k subs before presenting this creation....but you didnt...once again sticking to your own code of operations.That makes this channel very respectable...and is to me a smart choice.
I know it's outside the channels scope, but it would be awesome to see a TTC on the road: Traveling to mining companies to see how they torque those big truck tires for example.
yes hydraulic wrenches go crazy high especially cartridge style. i have 3/4, 1 and 1 1/2 drive hydraulic. 7000 ft lbs with the 1 1/2 which i have used to tighten an 8 inch tierod nut on a hydraulic press. it's not enough but worked well enough that it stopped stretching when the press went to full load at 900 tons.
Hytorq are uneventful...until they're not. 😂 Had a hose blow at 7000 psi. I got an oil shower but was very lucky it didn't rupture closer to me. It's really scary when you start stretching 3 1/2" studs to 40-60 KSI. Even scarier when you get so comfortable doing it you don't think about how much pressure that is anymore. Til something goes wrong and it reminds you how squishy we are.
If you're doing more Frankenstein creations with gas powered engines, try hitting up JohnnyQ and ask what he'd suggest. The guy seems to be a wizard at building tiny engines and gearboxes. Could make for an interesting collaboration.
First I love how things on this channel escalated so quickly haha and second I was really hoping for a NOS edition of the hot saw.... then I saw it is terminal 😢
The reason why you don't see a massive increase in torque with this driver and a lot of other drivers is the anvil and dog are not tuned to the power source. Basically you need to make sure that the anvil and dog have modal frequencies where their resonances have constructive interference with each other. You also need to take into account the motor RPM so the dog and anvil can maintain the right blows per minute to continue the harmonics. This is why sometimes you can see small impacts that have a very high output, while there are others that are quite large, however their torque output is underwhelming. In my opinion, a lot of it comes down to the tuning.
I’ve got the g660, only really ran it once through some wood so far, 32” maple with a 36” stihl bar and chain, rips like no one’s business, recommend turnin the oil up so you oil your bar more
I use the M18 1-in extended anvil gun everyday for work. I work on big rigs. There are times when it is not enough and I find myself reaching for the Harbor Freight Earthquake XT to break decently rusted lugs that I feel like the M18 should have no problem with. I've been lusting after that IR for a long time but I can't afford it. Not only is the earthquake XT able to break some insanely scary looking s*** but I can't help but wonder how much more powerful it is then the Milwaukee. And it's Harbor Freight and costs sub $500 I can't help but wonder how much more powerful the other big brands are.... I know you guys mentioned that you can't test these big guns with your current compressor setup. I'm able to run the XT on 3/4-in line from a 12 horsepower compressor with a 150 gallon tank. Line pressure will drop to about 95 PSI when giving it full beans but I don't think you can get much better than that. I guess my point is even without the correct air setup I think getting some data from the 1" air guns might help some of the guys out there that need the torque. Even if it does need a disclaimer about tested line pressure at the beginning of each video. Anyways, there's my little $0.03.
The biggest thing i've found that helps the big air guns is hooking your hose direct to the main tank, most compressors have a regulator that cant keep the pressure up. I also always use the bigger hose and couplers on 1".
Thanks for the fun video. Interested to see how an ice auger does now. Those puppies can rip! Electric or gas. 4 vs 2 stroke. My Honda lite 4 stroke rips ice like butter. Sure it can't be an impact wrench. But you can still try😁. Thank you for the videos!
You have the engines/motors, and you have an assortment of hammers/anvils to test. What you are missing is a proper transmission to transfer the power. Turbines could also be in the future... Or forget the LS and go to a Tesla motor. As far as the trans, a pulley/belt drive inertia system could be used.
On that chainsaw if you are planning for using it for anything else. I would recommend plugging the decomp or getting an OEM husky or Stihl, They are the same thread. The reason being is the clone's have been known to snap and drop into the cylinder.
There is a balance between the motor power and the hammer weight. The hammer unit itself, the leverage arm length of the anvil matters too. A shorter anvil (relative to the rotation axle) will require harder impacts pushing the limits of tool steel. However a very wide hammer reduces the ability to torque bolts making bolts closer to the floor/rock/wall/imovable object. See what you have done now I must spend the whole Sunday thinking about a large impact driver with an offset anvil so that you still can access bolts close to the floor and also have anvils with longer leverage arms.
My Sunday go to is project farm, but I saw this monstrosity and said heck yeah!! The stihl 440 clone might get you a few more RPM’s especially if you had it ported for high end rpm
I work in the track department and use these gas powered impacts almost daily, when I first started Ithought they would be stronger than they actually are. there are a bunch of times we end up torch cutting bolts off because the impact cant break them loose.
Great video. I think the IR gearbox should be adapted to your chainsaw setup OR the IR gearbox onto Milwaukee MX platform somehow. Possibly the core drill or cut off saw?
On big construction jobs we use big sline drive impact guns on 3/4 or some time 1 inch air lines that are instant air tankless systems the things are big and heavy. Test one of those comared to the batteries
Definitely worth venturing back into electric to chase some real beans.. for a few hundred bucks you can get a brushless motor & power system intended to replace a 150cc engine for (large) model aeroplanes! Sky high RPM and absolute tons of power. The hard part will be finding or modding a business end to handle it.
If you end up throwing Leroy's engine to it, make sure you rig up a push button HAMMER brake and 2 step. You know, for those 30PSI boosted uggas off the rip
alright, I haven't seen it suggested, but have you considered dipping into RC engines run on nitro? Might be the next logical step with their insanely high RPM figures.
Rc engines are too small. Even the 1/5 scale cars as large as they are just use a small weed whacker engine. That's part of the reason why they rev so high, cuz they're tiny lil baby pistons and con rods.
Can you make a handle that connects from where the dogs would be on the chainsaw to the anvil handle? Might be a little easier to hang on to. I love your creativity.
It'd be cool to see you team up with AvE, this old Tony, Abomb, or even fireball tools to come up with a slightly bigger anvil and a bigger spring design. Even if it was just slightly bigger I just like to see what gains or losses you get. Also while using the same housing.
I bought the actual impact side of your railway gun for less than $100 few years back. And I was going to mate it up to a chainsaw I kept trying to find small chainsaws that the clutch bell would fit I guess I'll have to buy another ms660 clone to put it on lol.
Make a super capacitor boosted battery with sold copper buss bars for the IR. Also, get an oscilloscope and look at the voltage drop at the motor inputs on the high torque guns.
with the same hammer, yes a 6l v8 is comparable to the railway thing, but with bigger hamerand spring it will snap bolts just loocking at them you can make an hammer and slap it to a car wheel, russian style :)
At 4:20 Explaining that RPMs are more important than horsepower and torque.... If you could have got your hands on one to borrow it, you may have won to try one of the old Honda racing motorcycle engines. Back in the '60s they had an engine in the 250cc size and 125cc size that had six cylinders and would rev to 20,000 to 22,000 RPM....talk about a screamer!!
I've said it before but will gladly say it again. Lipo batteries and the biggest BLDC motor ESC combo you can muster. Need rpm? How about 50k? Not enough you can get custom motors mad if you need 😅
In the past we made the 1st gas gun at 100K subs, and the 2nd at 200k. But when you put a chainsaw impact together and it works, you don't just let it gather dust in the corner until some number is hit. Enjoy!

Put a super bike engine on it ( I’m thinking R1 or triumph 675 ) they go up to 13000 rpm easily some even go too 16000.
Also they have 100 or more hp
You should get Walker to build you a Husky 395. He's on Jinglepot Road in Naniamo, BC, Canada.
hmmm. Maybe try and make a flywheel style impact similar to that amazon special egg beater

Try getting a monster RC brushless motor, like from castle or similar. 20k rpm and some over 10hp
You should frankenstein a kitchenaid mixer into an impact for all of the Husband's wives out there.
What about putting the saw on the IR? Or for very high RPM a modified RC jet engine :D
You got to do a turbo impact now. It’s the next step.
