Same. If it won't twist, i'll cut off the hose at the barb, then slice off sections like peeling bark off a tree. This thins the hose until it just crumbles off.

Best purchase in a long time! Matco's new 15" 3/8" Drive 88 Tooth ratchet. I have 3/8" Snap-On sockets up to 24mm, and 1", so it is awesome to be able to use the larger sizes in a small profile 3/8" ratchet in tight spaces with out sacrificing leverage:

I replaced my brake master cylinder and remembered how long bleeding takes the old fashioned way, and how poorly vacuum bleeding systems work.

Pressure bleeding systems supposedly work well, but are expensive, so I'm trying something I've seen a few times around the web.



$10 sprayer with the nozzle cut off, some plastic tubing and a hose barb. The cap from my old master cylinder with its vent hole drilled to fit the hose barb.

It worked to bench bleed my junked MC, but I want a way to read tank pressure before I try it on the car because 20psi max seems to be the prevailing opinion. Ideas? Tire pressure gauges aren't usually designed to give constantly updating measurements. I'd like to keep cost down because I'm under $20 so far.

This guy slapped on a pressure gauge if you really feel like you need a constant measurement, but I like the valve stem idea because that way you can pressurize the tank with a compressor.

This looks identical in functionality to my pricy Motiv unit. Works like a dream, as long as you have the right lid setup. Pressurize the master cylinder, go to each corner and just open the bleeder until fresh fluid comes out. Makes changing brake fluid so quick and easy you'll want to do it more often.

I think you'd have to be dealing with some seriously high pressure before you'd be in any danger of damaging your brake hydraulic system.

If you're paranoid though any low pressure (topping out at 100-125 PSI) gauge would do the trick. Something like this. You could just drill a hole in the bottle slightly smaller than the connector on the gauge, screw it in and then epoxy over the connector on the outside (inside too if you can reach it, taking care to not cover the hole that allows the gauge to function.)

I've got a lovely cheap dial gauge from Harbor Freight that actually might work this way, since unlike any decent dial gauge I've ever used, it doesn't have a button to reset - as soon as you take it off the stem, it goes back to zero.

They bleed plastic reservoir master cylinder cars on the vehicle assembly line with enough snot to make the tank blow up like a balloon. Sure, your 200k mile shitbox isn't going to take that the same way it did before it was ever even started, but it's really unlikely you'll hurt anything with any pressure you're going to get out of a hand pumped plastic spray bottle.

This.

I have one of the Motive power bleeders he's trying to duplicate on the cheap. It has a pressure gauge, and by the time the gauge is over 30 PSI it becomes difficult to continue pumping. Furthermore, if you generate enough pressure to make the brake fluid reservoir explode what's stopping the bottle from the sprayer from likewise exploding?

And if that's not enough, the weakest point of failure on his homemade power bleeder is the barbed connector on the reservoir lid. The hose will pop off and release pressure long before you're anywhere close to blowing up the reservoir.

ITs not really automotive related, but there is a tool store near me and the owner is retiring. Tons of poo poo on clearance. Well, not any more but there is still some poo poo left. I was in there today and saw a Porter cable Teks Driver on clearance for less than 100$ Their list price was 464$. Now, that seems like a loving great deal.

First question, I can't find much about it but it seems to me like its a drill thats used specifically for driving screws etc. What the gently caress is it for? Its it for people who spend a lot of time building decks and poo poo that are too lazy to hammer?

Second question, I have seen them for sale online for ~ 150 bucks or so. Now this is online, where everything is fuckin cheap, but aside from the fact that its marked down like 350$ is this a good deal? That might sound like a no brainer, but at a regular retail place would something like that really go for 400$ +?

I'm contemplating buying it and selling on Kijiji for say 350$, but I don't want to bother if some guy can go into a Home Depot etc, buy the same poo poo for 250, and this place just marks up their poo poo horribly.

There are a few other things (P.C. portable belt sander, random orbital sander etc) that I might buy as well.

Just for reference this is in where poo poo is more expensive.

So you can do all four corners without stopping to repressurize the bleeder...?

Also, I never said "I pump my power bleeder until the needle on the pressure gauge stops moving, every time I use it" just illustrating a point in regards to the "you're going to pop your master cylinder reservoir" comments.

When I worked construction, a lot of the stuff we used was Porter-Cable. It stood up to our abuse. Granted, I didn't work there for very long, but I felt like them actually paying money for it was a sign of quality (they did not use cheap tools).

So I ended up getting a P.C. random orbital sander instead of the Teks driver. I might even use it at some point. This winter I'm going to be refinishing some of the wood on my canoe and a couple paddles. I know its not going to be good for tight contours, but it will probably eliminate 90% of the hand sanding that I'll be having to do.
This particular model:

I really want a Fluke Ti25, but am having trouble justifying the $5000 price tag; the FLIR i7 I can justify simply because at $2000, that's pretty much as cheap as they come, and I need a thermal imager to do my job. The IR thermometer on my multimeter just isn't cutting it. Regardless, I think this FLIR i7 is going to "accidentally" find its way out of my work bag and into the track bag from time-to-time... I'd be royally hosed if someone ran it over, though.

Given how ubiquitous inexpensive CCD video cameras and small LCD screens have become I think these would fall under the category of "safe to buy at HF because its hard to gently caress up." Odds are they're buying the circuit boards and cameras from whoever makes them in China for major name brands and throwing them in "Cen-Tech" bodies.

You're right. I kept my distance. I had a remote shutoff switch. I also didn't disable the blade guard. So if it did come loose, the blade guard would have closed. It was also on a slanted driveway, I stayed uphill from the whole contraption. My hands also never passed over the edges of the table.

Yes, it was redneck as hell. if I am actually going to use that technique again I think I'm going to make a sheet of plywood that will be the saw mount.

That said, I don't foresee needing it much in the future. I know much more about the project I made, and can now cut all the pieces properly at one time. The delta table saw I was using to make the slats for my yurt turned out slats that were almost shiny due to how smooth they were. This thing left pretty rough edges.

That's a FLIR i3; different model with a little less capability than the i7. (60x60 resolution vice 120x120) For $5k, the Fluke Ti25 has 160x120 and also an optical camera which overlays in the software so you can tell what you're looking at.

I Want To Believe this poo poo will get cheap and common soon, but there's gotta be some valid reason they're charging over $1k for a 0.003 megapixel camera...

Edit: hey, wikipedia to the rescue:

wikipedia posted:

The CCD and CMOS sensors used for visible light cameras are sensitive only to the nonthermal part of the infrared spectrum called near-infrared (NIR). Thermal imaging cameras use specialized focal plane arrays (FPAs) that respond to longer wavelengths (mid- and long-wavelength infrared). The most common types are InSb, InGaAs, HgCdTe and QWIP FPA. The newest technologies use low-cost, uncooled microbolometers as FPA sensors. Their resolution is considerably lower than that of optical cameras, mostly 160x120 or 320x240 pixels, up to 640x512 for the most expensive models. Thermal imaging cameras are much more expensive than their visible-spectrum counterparts, and higher-end models are often export-restricted due to the military uses for this technology. Older bolometers or more sensitive models such as InSb require cryogenic cooling, usually by a miniature Stirling cycle refrigerator or liquid nitrogen.
Guess convergence into cell phone CCDs may take a while longer

Maybe I'll have a go at fixing the AC in my Grand National. What are the steps you would generally take? Do you vacuum the H high pressure port and fill the low pressure port with refrigerant? Also what is recommended for refrigerant? I remember someone talking about R12 Freeze or something? Whatever it was it's supposed to be better than R134a and not a pollutant like R12.
