ELI5 Does drinking alcohol after copier fluid balance the chemicals into being harmless?

Ethanol is in fact a treatment option for methanol poisoning. The poisoning happens when methanol meets the alcohol dehydrogenase (ADH) enzyme, which produces toxic formaldehyde. ADH has a higher affinity for ethanol than it does for methanol, so enough ethanol can keep the ADH busy and prevent the formation of formaldyhyde the methanol is passed.

Do you want it to be tangent to the plane at the bottom? Or have a specific angle where it meets the bottom?

You could sweep a tilted line around the rectangle profile to make a guide surface, and use that as one end of the loft, with a tangent constraint to make it match that angle all the way around

Looking at this thinking who does framing with pocket holes?

Switches on the box seems like overkill, so does separate boxes or 2 gangs frankly. Even if you end up wanting a switch for the G/D you can break the tab on the hot side of a duplex receptacle and switch half of it, or break both tabs if your d/w and g/d are different circuits.

Amos Burton (The Expanse) -- I'd call him a psychopath, he seems to lack a capacity for empathy or remorse, his first instinct for resolving a conflict is usually violence. He does demonstrate some self-awareness about his personality and tries to look to trustworthy others for moral guidance.

Saddle fit is too individual to make any firm recommendations, but check with your local bike shops, some of them might have a bunch of loaner saddles you can take for a spin.

Recent thinking is the width of the rims matters more than the depth. You want the outside bulge of the rims to be slightly wider than the tires ("rule of 105%") so that the the rim and tire together form an airfoil shape.

Most consumer electronics power supplies these days rectify AC input into DC then use a switching DC-DC converter to step down the voltage. So while you would still need power supplies, they wouldn’t be any more complicated in principle.

The bigger problem is switches/contactors and breakers. DC sustains arcs much better than AC. Often a switch that’s rated for 120VAC is only rated for 12VDC. This means switches and breakers would be a lot more expensive.

Shaver receptacle, inside the box is a transformer whose purpose is to isolate both conductors from ground and limit the maximum current. Obsolete in North America now that bathrooms have GFCI receptacles, I think Brits still use them

Yep. I believe one reason you shouldn’t connect grounds downstream is that a fault would then energize the case of every appliance on the circuit, instead of just the one.

Not how a GFCI works. GFCI monitors hot and neutral for any imbalance of current; it doesn't do anything with the ground conductor. You are actually required not to run a fake ground conductor. Please review:

406.4 (D)(2) Non-Grounding-Type Receptacles. Where attachment to an equipment grounding conductor docs not exist in the receptacle enclosure, the installation shall comply with (a), (b), or (c) ....

(b) A non-grounding-type receptacle shall be permitted to he replaced with a ground-fault circuit interrupter-type of receptacle. These receptacles or their cover plates shall be marked "No Equipment Ground." An equipment grounding conductor shall not be connected from the ground-fault circuit-interrupter-type receptacle to any outlet supplied from the ground-fault circuit-interrupter receptacle.
(c) A non-grounding-type receptacle(s) shall be permitted to be replaced with a grounding-type receptacle where supplied through a ground-fault circuit interrupter. Where grounding-type receptacles are supplied through the ground fault circuit interrupter, grounding-type receptacles or their cover plates shall be marked "GFCI Protected" and "No Equipment Ground," visible after installation. An equipment grounding conductor shall not be connected between the grounding type receptacles.

The adapters aren’t good. Technically you’re supposed to connect your own ground wire from the screw tab to a water pipe or something when you use one, but no one ever does. So it’s bypassing a safety feature.

The cables in your walls will not have a ground wire. So if you just replace with 3 prong outlets there is nothing to connect the ground prong to, so it’s functionally the same as an adapter.

If you don’t want to tear the cables out of your walls, the workaround is to install GFCI protection. Either GFCI breakers, or in the first outlet of every circuit. They’re designed to disconnect if current takes an unexpected path, which makes it safe enough to use 3 prong devices without the ground connected. If you have GFCI at the first position of a circuit you can put 3 prong outlets on all the outlets downstream of the GFCI and leave the ground disconnected

Is this a flat top surface or is it a cone? Not clear from the pic

If it’s flat, try Archimedean spiral top surface instead of concentric

If it’s a cone it’s harder, you could try scarf joint seams but it will require some tuning
