    Why doesn’t the snow melt?

    Maybe the replacement squares are a different thickness? That's a weird effect for sure, but it has to be related to heat from the ground, or stored in the slabs.

    Laser level

    Those three plane lasers have the added ability to act as a plumb. Where the lines cross on the floor is directly beneath where the lines cross on the ceiling. I have a couple of the sub $50 versions of that, and they come in handy for all sorts of things. Kind of. But if you're doing a...

    How many cans of PVC cement...

    THF is the actual PVC solvent. The MEK is a thinner.

    How many cans of PVC cement...

    I'm with you, and I don't bother to buy anything larger than the smallest available can of cement that meets my requirements. But I will add that I purchased the cap tool, and it helps quite a bit. Channellocks tend to mash up the cap's roundness, making it more difficult to seal and remove...

    terminating single mode SC fiber connectors

    Yeah, it's a new-ish terminology. Wi-Fi 5 = 802.11ac (though I've never seen the Wi-Fi 5 designation marketed) Wi-Fi 6 = 802.11ax (on the 2.4 and 5GHz bands) Wi-Fi 6E = 802.11ax (same as above plus the 6GHz bands) Wi-Fi 7 = 802.11be

    Sparky's Essential Electrician Tools

    I think the file angled pulling teeth in the front jaws are a feature unique to Klein, and I do like that for pulling insulation when stripping wires, but I like the hinge on my Knipex so much more than any of my Kleins.

    Sparky's Essential Electrician Tools

    Basically an insulated slotted screwdriver with unique features. More metal is exposed at the tip than a typical insulated screwdriver (so it can fit deeply into a clamp release slot), and it has a long, consistent and smooth taper (almost like a wedge). The tip width is about right for...

    thermal imaging cameras

    There is a parallax error issue with these dual sensor systems that merge an optical image with the thermal. Because the lenses are inches apart, they digitally compensate for this but the accuracy of those outlines depends on how far you are from the surface. If you switch to a strictly...

    thermal imaging cameras

    Keep in mind that the thermal sensor's native resolution is going to be much lower resolution even than the screen of an old timey mp3 player, and the sensor's resolution is what the camera is up-scaling onto whatever screen (built-in or phone) it's shown on. So I would look at the sensor's...

    Water supply diverter valve

    Look at 3-way ball valves. You can get them with the ball drilled in an L with all three ports the same size (full or standard port), or the cross drill in a smaller diameter.

    Anode length and drain size American Standard water heater

    Color me surprised too, but hey, I'll take the impact success for a win. As for the "new" rod, I'm not positive that's a great sign. If it's a factory aluminum rod and it's showing no signs of corrosion, that could be the corrosion control chemistry in your city water is working well, but it...

    Help Identify tool that has stumped thousands

    The only part about that that makes sense to me is that it looks like it holds something as a form. But the use of springs and metal contact surfaces just doesn't add up. Steam bending jigs use wood, because you don't want to dent the hot wood, and they use wedges and clamps, because springs...

    Am I reading this meter correctly

    That's a good explanation for decibels, measured in dB, but I'm not sure what DB is either. Maybe it has something to do with this meter's DB scale going to 11.

    I doubt it, but I've had no problem using pneumatic 1/2" impacts to do the job.

    Metal Science Question

    I wouldn't risk it. You run the chance of creating a hot spot, which can burn out the heater. That's a LOT of heat to reach 105F. The less material you have blocking the titanium from liquid the better. I don't think you'll have any corrosion issues connecting that titanium tube to a...

    Metal Science Question

    I'd use something non-metallic, like a piece of porcelain tile.

    Am I reading this meter correctly

    There's a parallax issue that we can see in the mirror on the scale. To my eye, I believe that if the camera were placed so that the needle would obscure it's reflection (as it is supposed to be read), the reading would be OVER 9.6VDC, even though it's just under the line for 9.6 right now...

    Oetiker / double ear clamps question on sizing

    Maybe, but only if you've got a death grip. Oekiker tools aren't all that sharp, and the ears are designed to be closed to the point that the metal makes contact (and then springs back just a bit when you remove the tool). Push beyond that and the nippers start to dig into the metal, but doing...

    I need to “Re-Light my Gun Safe”

    20 something years ago, I installed an LED rope light around the perimeter of the door opening, with an inline rocker switch on the plug attached in a spot easy to reach. By going full circle around the door, I find there aren't any shadows anywhere, and I didn't need to light individual...

    Anode length and drain size American Standard water heater

    Once you go anode rod shopping, you'll find that the rods for 40 and 50 gallon heaters are all pretty much the same length. Assuming you have a ceiling overhead, you'll want a segmented "flexible" anode rod. That's bunch of metal anode sections connected with a stainless steel cable. Don't...
