Remember that big impact i got from Iggy?

I am glad to hear that the impact worked. I have to wonder, just how strong are you if you could manage to hold the impact that was giving such an incredible strain to that nut.

I'm pretty much superman. (: Actually, it's not too hard to hold onto as long as you keep it straight. Feels like about a 30 ft-lb twist. If you tilt it any, though, it'll cam itself off the nut and kick back hard enough to knock you over. I always lean on it and make sure I know where my head's going to go if I should fall back. It's still starved for air, though. I put it on a 3/4" hose, but need more like a 1" or 1 1/2" line to get full blast.

Sounds to me like a job for the Victor Wrench.

Arrg, arrg, arrg!

Was it a left hand nut? MG

If you had restrained the yoke with something like a big pipe wrench it probably would have loosened the nut as well as saved the gears. Any rotational flexibility will greatly reduce the effectiveness of an impact wrench just like trying to hammer a nail into a flexible board without backup. Extensions even make quite a difference.

Oh, I know. I was just impressed with the damage caused by my little impact, that's all. I actually swap these things out on an almost weekly basis, so I'm pretty familiar with what I can and can't get away with most of the time. Usually when I get one stuck so bad the impact won't budge it after a second of hammering I just torch the nut off. I also typically brace the yoke against a jack stand. But we were out of acetylene and I already had the diff out, so I could either hammer it off or bolt the thing back in and set up the torque multiplier to get the nut loose. Hammering seemed more expedient at the time. I did eventually beat the nut loose by wrapping a chain around the yoke and carrier and letting it wind itself tight. The gears were screwed anyway, (bearing adjusting nut spun out) so no big deal. It was just neat.

That impact, IIRC, was a 3,000 ft-lb impact, right?

And the CFM was what, 70 CFM? The air delivery issue, maybe, can be addressed by having higher hose pressure, and putting a regulator closer to the gun?

Congratulations on having something that seems to work.

By the way, I have a big ass compressor hose with twist on air fittings, like you see on big tow behind compressors on street. I would say it is 100 ft, 1"ID hose, though I would need to check that, it could be 3/4" ID. I would be delighted to get rid of it by selling for not too much. Say $100 plus shipping. Full refund if not satisfied (you would need to cut it in pieces and break the couplers to get the refund), shipping is not refunded.

That's highly impressive... I had a piece from a phantom at some point... Gave it to some Rec.Crafts.Metalworking member for free... (round stainless thing)

Supposed to be, but I can't be sure. I do know that nothing has stopped it so far.

When I use the gun I don't go through a regulator, just straight into the shop air system, which is around 130-145psi most of the time. Running that gun for a few seconds will kick the compressors on every time.

Let me know if it's still available in a month. I'm flat assed broke right now. But yeah, that would be perfect, I even use twist-claw couplers myself on some stuff. The couplers look like McMaster #5344K43?

I can't make very firm promises, (in case if a sudden buyer comes along) but I would be surprised if it was not available in a month. Let me know. I am very tired right now (after the trailer) and am not actively selling more or less anything. I can barely do anything at all. I spent Sunday just trying to lay wherever I was.

GACK!!!!!!!!!!!!!

Political Correctness

A doctrine fostered by a delusional, illogical liberal minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

That's one you wouldn't want to land on a dirt strip in the middle of BFE and shut off, is it?

(I was never impressed with the design of the Phantoms, esthetically or otherwise.)

I'd guess it takes a lotta air to spin up those engines until the pilot can open the throttle and hit the ignitors. At 16, I went on a road trip from OH to Tacoma WA. We went because one guy's uncle's daughter was due to have a baby. Her husband was a jet engine mechanic at McCord AFB.

Got to watch them test self-starter charges on F106s. They were like little rocket engines firing into the turbines. Lotsa smoke and noise and the poor pilot had to do the start sequence just right or all he got was a lot of white unburned kerosene smoke with pops and flashes because the compressor turbines weren't up to pressure. I sure wouldn't have wanted to have to try that under a scramble with enemy planes on the way in.

I never did hear if they got that system worked out or just gave up on it.

Question: Why did flying in a DC 9 feel like riding inside a vacuum cleaner? I never rode one where the pilot got the engines well enough synchronized to stop that growling beat frequency and the thoroughly annoying whine.

Hi BB,

Are your work stations laid out such that you might be able to snag another 3/4 inch line hose from another point? Two hoses are better than one!

You would have to eye the pipes feeding the stations, but I suspect that they may be plenty big enough. Then you would have to make a custom manifold or a small pig-tailed hose with a shut off (you don't want to plug in an air hose and end up with an open port with out a hose on it yet) and dual fittings for your impact. Then you would just have two standard 3/4 inch hoses that would be useful for other stuff too. You probably wouldn't need to use it all that often. It sounds like it works pretty well with your current set up :)

I LIKE that idea. Justifiable, yet looks like absurd overkill. (:
