Who’s subscribed and who went over based on SMA recommendation? Thoughts on the test process.

I both like the channel and wish they would move away more from just impact wrenches, that dyno has potential to bust a lot of myths that even I find myself reciting sometimes with no actual proof. But I do like head to heads just for curiosity sake.
I also do like the graphs, all these videos on YT with some guy shouting at me then removing a bolt he set to 400 ft-lbs is cool to see but is not great for actually comparing tools and their claims.

Seen all the videos. Keep in mind - there isn't a common torque rating standard. So he is not trying to prove/disprove manufacturer ratings. He is simply benchmarking the tools and comparing them against one another. Although in some cases, he can prove/disprove manufacturer claims. For example - the % power increase of Milwaukee batteries.
I'll admit I was confused at first. I was like no way does that impact only make 611 ft-lbs or whatever. But then I watched a couple more and it's like 611 ft-lbs based on an old IR being a true 450. Then measuring all impacts with that same "ruler"
Only makes sense once you have a lot of impacts tested to compare

Watched a few. I don’t make purchasing decisions based on it though. Ultimate torque is a one dimensional number. There are ergonomic, cost, Reliability and probably a number of factors that go into making a decision on what tool is best for me.
Also, tests like he performs really should be repeated enough times to insure statistical validity. I haven’t seen that, although it may be there.

Same here, I started watching TTC videos before he tested that impact from SMA. I don't watch SMA.
Some may not agree with his testing methods & I don't rely on his numbers for actual ratings but it's good to see someone testing stuff with a different method other than simply tightening/loosing with a torque wrench that so many others do.
I used an IR231 (the impact he's basing his numbers off of) for years when I worked at a shop so I have somewhat of an idea of it's power & how the impacts he's testing compares. But of course that don't mean much cause the power of his IR231 currently has could very well be different than other IR231s & I'm just going based off memory which is getting worse & worse with age.
But if he continues to test more & more of the popular impacts it gives an idea of how they compare to each other with his numbers & method of testing. To me that's better than the tests using torque wrenches from various random people.

Watch and subscribe. Nice no BS, no screaming or cursing or stupid sophomoric humor. I like the real world stuff like different hose and battery sizes. Teaming up with SMA made it all the more better!

Yeah, and an old 231 don't make anywhere near 450.
It's just for comparisons sake, and better than nothing. Manufacturer ratings are worthless, so it's a nice data point.
611/450 = 1.357 = roughly 35% more power than the IR, on that test rig, with that socket. For instance, even if the IR did make 450, it ain't putting 450 into a lug nut with a flip socket. Part of the output equation is the mass of the socket used. He's using a big *** axle nut socket.

I subscribed on the strength of SMA being tagged!!!
I liked the bit when he ran water through his impact and just laughed it off (keeping it real)
It's got to be an Astro Pneumatic gun??
They have picked a great poster boy in Eric O to "test their products"

I liked the graphs a lot. Mostly I’m interested in how the guns performed in the first 3-5 seconds, not peak torque achieved after 10-15 seconds of hammering. So when he compared the recent lot of M18 guns, that graph painted a more realistic picture...for me. I still haven’t upgraded since I have no complaints with my gen 1, but if I were trying to choose between gen 1 and gen 2, those tests would be invaluable in deciding how I spend my money.
I'm not so sure, does AP even make full frame impact wrenches?
The channel said they bought an OEM tools one that looked a spitting image to Eric's but the guts were all different and it didn't perform.
If Eric's had it over a year now, where is it??

They are the only "sponsor" I've ever seen on SMA, and he has obviously handed it over to be tested, and he always does the "secret squirrel" act with their tools
It's gonna be AP
If so I wonder if it will actually be $250, not that it's an unreasonable price for "the best performing impact" out there. Just seems like AP is usually on the more reasonable end of pricing.
Maybe it needs to be further proven out. Especially if it has a 2 year warranty Id hope they tested it for 2 years.I'm not so sure, does AP even make full frame impact wrenches?

Good luck to them, I know they frequent GJ and Eric is a great ambassador/tool abuser!!!
I wish we could get AP in the UK!!!!
So much better than getting Milwaukee reviews on day two by some corporate buttkisser who only works on pristine automobiles
I watched Gordon Murray being interviewed about his T50 supercar the other day
He knew the weight down to the kilo and the exact power of the V12, when they asked him how fast it would be??
"I don't know, really fast though"!!!
You can't beat honesty in marketing!!!
Does that channel have a simple or running table of results. I'm not in the market but I am curious how the old school IR231 that is his standard ranks compared to the newer stuff. Yes, I can watch a number of videos and write down the results but if he has a published table that would be handier.

I honestly don't know but he typically shows at a chart at the end of each when he "ranks" the one being tested. So find the latest and jump to the end, then start working backwards

I have been watching it since day one also. IIRC it was posted up on here and I subscribed.
I don't think that his tests are necessarily better than any other tests when taken one at a time, but the value of having multiple tools all tested with the same methodology can't be overstated in my opinion.

I like that it isn't shouty and that it's the same methodology applied over all the systems.
I would like to see them verify their rig hasn't sustained any wear/etc. that might be affecting the results. I'm not a test engineer, so I'd be interested to know if their methodology has any holes that show up in real-world performance.
I also wish they'd externalize their data so I can re-weight their ranking based on my own preferences.
I do appreciate that they state pretty clearly the narrow field of what they're trying to do.
All in all, a good point of information.

He did say in one of his videos that he puts the IR 231 (that he bases everything off of) back on the test rig every so often to make sure it stays at the same result as the 1st time he tested it. It has always been within 2 ft lbs ( or lb ft, whichever you prefer
) each time he tests it.He did say in one of his videos that he puts the IR 231 (that he bases everything off of) back on the test rig every so often to make sure it stays at the same result as the 1st time he tested it. It has always been within 2 ft lbs ( or lb ft, whichever you prefer
Good to hear - thanks!
I like the way they test everything, even if it's based on an old impact. Since there are no standards, he's made one and you could graduate it anyway you want. The PSI generated from the old IR gun could be a value of one. If the Matco makes 50% more PSI on the measuring tool it could have a "TTC rating of 1.5". Kind of like Tread Wear Ratings on tires based on some gubmint "100" rated tire.

I like it and think that he does a great job. That stated I really don't care if impact A is 20 ft-lb stronger than impact B. All I give a **** about is whether or not it removes the bolt I'm trying to take off. Living in Arizona I seldom need to use a monster impact. My mid-torque has never failed me.
I think every tool on there is compared to the IR making 450, so it's pretty simple if you're interested in the 231 comparison. If a tool make 390 it's almost but not quite an IR 231.
Plus I think he has like 20 bolts/nut, and no real way for the hydraulics to wear unless there's a leak

Still waiting to find out the make and model of that "mystery" impact gun !
Has anyone noticed that Eric O. has kind of given up on battery impacts ? I don't recall seeing any in the past couple of months.
The AVE tear down of one of Eric's battery impacts basically revealed that they all have a finite life and it is shorter than pneumatic impacts, especially in heavy use situations. Plus pneumatic impacts are cheap and easy to rebuild.

Been almost a year but it's worth updating to say it's the Astro Pneumatic 1894 "Thor" that frequently goes out of stock but never seems to be more than $190. Usually a bit less.
