    Residential electrical switch box covers: why not Phillips?

    Maybe the slotted drivers slip out enough times that the person turning the screw says" Effit, good enough!" long before it gets overtorqued.

    Why don’t pullers use acme thread screws?

    Fun Fact: Toothpaste tubes use a buttress thread for the cap. Why that is, I have no clue.

    M10 SAE Flare Line Nut for Unloader valve needed (solved)

    Looks like lots of alternatives available. This one gets you a female thread that you could put a proper compression fitting in. https://www.amazon.ca/s?k=air+compressor+check+valve&crid=2BSF63Q3AIIQ6&sprefix=%2Caps%2C94&ref=nb_sb_ss_recent_1_0_recent

    Need an ace Commercial Air Compressor System Specialist in SF southbay area, can anyone help?

    Copco owns CP. Given their depth of knowledge, it would be hard to go wrong with Copco, but you're going to pay.

    Can anyone find one of these 12v impacts

    AC Delco likes to change battery styles without changing the tool, so you're up the creek after a few years even though it's the same tool. I won't buy any more of their stuff. This impact is pretty much the same tool I bought in 2007.

    IR 253 VS 2475

    Keep the 253. Rebuild parts are dirt cheap should the need arise. The minimum rpm of the 2475 is already higher than the max rpm of the 253. Sounds like the usual IR practice of moving a small pump up a horsepower class by revving the hell out of it.

    Air Compressor Issues/Troubleshooting/Insight

    Might be a holed piston from a broken reed. One cylinder might be doing all the work.

    Does this air compressor look like it is worth trying to save?

    This is a Campbell Hausfeld TF000021P pump. Unscrew the pressure relief valve on the cylinder head on the low pressure cylinder. Put in a gauge and run the pump. If it goes to about 30-40 psi while running and does not follow tank pressure above that, the valve plate is good. If it is jerky and...

    What knife are you carrying today?

    I usually don't carry anything but these were supplied at work awhile ago and it comes in very handy. More than I thought it would.

    Sewer Snake

    Pro showed up at 8am last friday. She called me and asked what to do. I said let the pro handle it, you'll know it was done right and more importantly, I won't have to get involved. It was taken care of, I got some well deserved sleep and she finally calmed down. Well worth the $625. She said...

    Strange Motor Problem Instantly Trips Breaker When Plugged In

    I'm not talking about the box. I've seen ground wires sparking when I disconnected them because someone was using ground for a neutral.

    Could a neutral be bonded to ground somewhere in the house?

    Sewer Snake

    Got a quote for $825 just to snake it out from a plumber. Could be higher depending on what he finds. I contracted another company to come have a look for a $99 diagnostic fee. Probably won't be any cheaper. Looks like I know what I'll be doing tomorrow.

    Sewer Snake

    I'm assuming a standard 4" iron pipe. House was built in 1959. No problems as long as I've lived in this city (25yrs) but I've witnessed the flushing of paper towels recently which raises my suspicions. There is a reason public toilets ask you not to flush hand towels. I noticed someone at...
