Kind of, but also phenomenal 3D viewing when you have them setup correctly. You need to set them at both just the right interpupillary distance AND the right conversion angle (for each individual eye), and then the view is magically immersive. Also, I discovered inadvertently that if I use a...

In this day and age of "smart" switches, one option is to install the wired switch further from the shower and install a remote "switch" wherever you want. I have some remote "switches" that the pressure from clicking on and off generates all the power it needs to send the signal to the base...

Or a radius gauge, or a thread rule.

Fluid Film thins out a whole lot when heated. I'd start there. The 3D printer bed isn't a bad idea. In the shop, I'll sometimes turn a lamp with an incandescent facing up and sit my part to be heated on the bulb.

An SDS+ hits like a short barrel. An SDS-Max hits a whole lot harder. This is something in between. Honestly, 7 joules is kind of a sweet spot here, being similar to my beloved CP717, though still a whole lot chunkier.

Factory belt grinders have enormously long belts. This certainly could be the driver with a tensioner to keep the belt from bouncing on the drive wheel.

Two reasons: First: the very most a surge protective device can do is clamp the line voltage to the ground. That's fine when you're at the panel where all the grounded wires meet. It may not be fine at some distance to the panel with a device sitting on the actual ground outside (or on a...

The voltage from a surge rises as fast as the electric field travels (basically, a decent fraction of C). Adding inches of wire between the bus and the surge suppressor delays the protection enough to make a big difference (after a few feet, it's so bad that the suppressor will effectively...

I fill a thermos with hot water when I'm doing a lot of irrigation work and dip the pipe into it. It makes a huge difference with how workable the PE tubing is.

When you're hammer forging damascus, the "size" depends on what step you're at. Having an adjustable wrench makes good sense, and having two handles to balance the force when twisting also makes good sense.

The exact same arguments could be made about natural gas. The difference is that we have a long history of learning about natural gas failure modes. H2 still has an LEL and UEL, and the LEL of hydrogen is 4%. Natural gas is 5%. Propane has a shockingly low LEL at 2%, but the biggest risk...

I believe that CT scans are used on most airport checked luggage, but that's not what's used for carry on luggage. CT scans send the x-rays through the object being scanned to show the mass that the radiation has to travel through on that scan path (kind of like density). It's basically a 3D...

It offers less corrosion resistance than the "browning" I'm suggesting. Which BTW means that acid cleaning to bare metal is not actually helpful. If you keep cleaning to bare metal, you'll continue to get "flash" rust, which washes off quickly and leaves a stain trail. You need to build up a...

For single speed systems, permanent capacitor motors. The run capacitor is always in circuit with the second rotor winding, and there is no centrifugal switch. For variable speed systems, they usually have some sort of inverter with either a 3 phase or brushless DC motor, and no single...

So, what a centrifugal switch does depends on the motor design, but for the purposes of a general purpose induction motor (which is NOT used in a residential central air conditioner, but might be found in an air compressor) it usually disconnects the start windings and starting capacitor...

I'm gonna have to call you (and TOW) out on these details. AC capacitors don't charge up like DC capacitors. While they do hold a charge (since they are capacitors), they charge and discharge with EVERY up and down swing every cycle. The actual capacitance of an AC run cap (and these are RUN...

It's sometimes easy to fashion a replacement. Depends on what sort of end the manufacturer uses. The upside to a spring wound housing without a vinyl cover is that moisture has a way to escape. I've seen many coated cables with a U bend rusted shut at the bottom of the U (NEVER allow the...

No comparison. But after growing up with these rust issues in cast iron sinks, I've always had vitreous porcelain sinks in my bathrooms and stainless sinks in my kitchens. The rust line coming down from the overflow is a nuisance, but when the rust creeps up from the drain and chunks of enamel...

I wouldn't bother with any sort of paint. You're never going to completely rustproof the inside of the overflow passage, and with paint, if there's ANY room for rust to start, you've lost the war. I'd use a lanolin based corrosion inhibitor. Fluid Film would probably work ok, but it's a bit...

Sorry. That's what this site does to us. You probably wouldn't use more than one at a drill press. That's all I've got, though my electrician bought his after seeing mine.
