The N2O pump usually tops out around 200 but the gauge may be wrong, I fill by weight anyway. Here are the videos.

I should dig up some pictures of the completely failed N2 bottles I've seen. I am fairly sure there is a industry standard designation of low, medium and high pressure air. IIRC you go from low pressure to medium pressure at 500psi, and from medium to high at 1800psi. Anything up from there is high pressure. If I wasn't worried about the consequences, I have a compressor at home that will pump up to 9000 psi...

Quasi-crosspost from the stupid questions thread (friendgoon Susan Calvin is the owner of the car, I just took the picture) - The tire keeps going flat, I guess I'll take it to a shop and have something looked at. - We replaced your TMPS sensor with a plain valve since we don't have the replacement part. Here's the old one. Stop using metal valve caps. The body of the sensor is fine, but that's a pretty sweet valve stem failure, especially when you consider the cost of the unit is (she's told) $140+ from Ford/Mazda. Thanks, technology! Too bad there isn't a mandatory 8yr/80k warranty for the stupid safety poo poo the feds mandate like with emissions equipment.

That's what the guys at pep boys claimed. I don't know if it's corrosion or weird forces from being heavier than the plastic caps that they would blame, though - as far as I know, they only said it was the metal cap to blame, no speculation shared.

I never ran into the issue in California but as soon as I came up to Seattle I've been seeing a large number of sensor failures due to corossion from the metal caps and moisture so there is definitely something to it. Mine twisted off just like that picture, too. Use plastic caps and the new TPMS sensor hardware kits even come with plastic caps to replace.

Yeah, I've had aluminium caps seize onto the valves so badly I had to cut them off. They probably tried using a spanner to undo it, and that's what's made it that shape. A Dremel cut along the side and some levering with a flat screwdriver might have gor it off without trashing the assembly, but there's no way to tell now.

This reminded me of something a colleague of my wife said about the perfect gift several years ago - "Does he have a Dremel? Because if he doesn't have one, he definitely wants a Dremel." It was true, of course. I have no idea why I didn't have one already, now I have one as well as a million little attachments in a little tackle box that's now the Dremel box. I don't know why they don't market it that way. Apologies...

I bought an off-brand version and it is very useful when working with old stuff, removing grime, chopping small bits off, grinding etc. A cutting disc will cut 7/8ths of a bolt before it shatters.

I have a Black & Decker "Rotary Tool" and it's excellent. It was around half the price but is compatible with all the Dremel discs, etc. My favourite use so far is as a headlight polisher.

We bought a cheap rear end Job Mate (cheap canadian tire brand) rotary tool and it sucked so hard, got hit in the face and arm a few time with shattering wheels, and the fact that its attachment method was horrible, I havent touched it in forever. My mid level Dremel on the other hand is wonderful, the quick release cutting wheel system they have now rocks, and that thing can cut through anything. I used it to cut off one of the almost 1/2" thick steel tow hook on the back of my 240sx and it only took about 5 minutes because of the awkward angle, and it did it with only one wheel.

Mine twisted off just like that picture, too. Use plastic caps and the new TPMS sensor hardware kits even come with plastic caps to replace. Chrysler is the worst, they actually come new with metal caps. The caps practically weld themselves on until they corrode through or someone breaks it trying to unscrew it. I keep so many Chrysler TPMS sensors on hand just because of that. The early Fords did that also but since they use the band sensors now it is so much nicer. Band sensors should be the only sensor used.

Well, you're supposed to close the cowl flaps when you fail an engine, otherwise it gets cold really fast.. but this flight school has terrible standards, so most of their instructors don't bother. Over time, it ended up cracking the engine in the process, and when my friend went up in it, he leaked out all the oil, overheated the engine and blew a cylinder. Maintenance gave him that as a souvenir, it's their 5th blown engine this year.

There is no in-between. Automotive polishing 101: Remember you're using a rotary buffer. Keep the pad moving, don't focus for too long on one spot, and don't allow the surface to get hot or you will burn through your clear coat. Don't try to rush the job, polishing takes patience.

My dremel paid for itself the first time I used it. I used it to re-cut a mangled keyway in a fan hub, a replacement hub was $120, the dremel was $80. I've had it for going on 15 years now, replaced the bushings once and other than being a little louder than it used to be it is still going strong.

You know what's fun? Having like 30 of those wheels ready to go when you're all set and stoked to get cracking on a project. And no goddamned shaft.  And the reason it sucks so much is because goddamn do they ever rip through steel, they're great.

Ok since it's DREMEL CHAT ITT I was wondering something. I've seen Dremels with those long flexible shaft extension things so you can work in weird places and angles. Is there something like that I could get for my pneumatic die grinder? That would be slick. I tried googling for it but I don't know what to call it. E: I guess it's called a flex shaft, but I can only find new grinders with it permanently on there as opposed to something I can remove.

It would be pretty hard to manipulate it if the shaft is attached to it like that. Also air grinders haul rear end, it would probably melt if you tried to run it at a reasonable speed. After my Dremel exploded, I got one of these: http://www.astrotools.com/default.aspx?toolsnum=218& . drat fine upgrade I'd say.

Was the guy who designed the Dremel left handed? The way it spins makes it so that using it as a right handed person normally would causes all the debris to fly right into your face.

I have a great corded Dremel for 10+ years and one day it just refused to turn on anymore. I took it apart and everything seemed ok, I even bypassed the on/off/speed switch but that failed too. In a serious pinch I bought a $10 rotary tool from Harbor Freight. It was a mistake. It doesn't have enough speed to cut anything, even balsa wood, and has so little torque I can stop the disc rotating at full speed by just pinching it with my fingers. Huge mistake, but a cheap one. For christmas I got the Lithium-battery Dremel and it's been really great. I wish I had a second battery sometimes, but that's rare. At least the Harbor Freight one came with a shitton of cutoff discs that work just fine on the real tool.
