No state that I know of had different rural or urban masking or emergency worker restrictions. Every state applied nonsense statewide rules.

Policy makers first concern should be population density. If you look at COVID response it was stupid and irresponsible to make rules and edicts that applied equally to rural areas as well as million population urban centers.

Drain valve is slightly open, unless you are saying you can set it to 40 psi and it eventually shuts off and hold pressure for hours. In which case it's just broken.

No that's why nasa is testing it. Most of this was developed at AFRL. I'm guessing for upper atmosphere unmanned drones.

You let it sit with chemicals in wet environment and it corroded maybe questionable coating. Plating isn't important there, the top part matters more.

Reply to Trying to attach a 2x8 grid panel to the frame of a French door to use as a cat-proof gate. I would like it to be on a hinge so it can open and close. Since the panel has 4’’x4’’ openings in the grates, what kind of a hinge should I get? by The-waitress-
They make screens you Velcro or sticky tape to frame. I assume French doors open inwards and this door leads to back yard?
Etc
Otherwise I would make 2x8 frame from wood (2x2s if you find straight ones) and attach screening material (groove and rubber spline or just wrap in thin wood and staple to frame. Then figure out how to Bungie/ attach frame to both door handles when one is ajar.

It probably won't be to code if you slap in those mini breakers, because they put in the AFCI or combo AF/GF. Your homeowners won't cover you if something happened.
Your real problem is I don't think you have enough overhead to slap another 60A in there. You might be close to limit if 200A service. You might want to check, but I'm the summer of you have 50A to car charger and two 30A A/C units running, and you have say electronics lighting, fridge. Then you turn on stove, it might exceed your service.
The better option might be to put in a sub panel of a 100A double, and move the A/C breakers to it and add car charger there in a sub panel with 8 slots.

Lolol. (Unless you meant kg)... You could mount it directly to stepper shaft. But technically risk eventually wearing out motor.
Maybe a small right angle gear box. https://www.ondrivesus.com/miniature-gearboxes
You certainly don't need any significant bearings.
I would personally hose clamp tubing between the two shafts as a coupler and put little wheels/dollies/ upside down ball bearing wheels for antenna assembly.

Correct, they should have ratings, usually hundreds lbs to 30,000 lbs.
If there are teeth on outside, you can drive it with a belt or teeth. But the stationary side didn't have teeth.
You haven't indicated any idea what kind of weight you need to rotate.

Reply to Proper use of ball bearing for a vertical rotation (azimuth rotation for a ground station) by Fun-Palpitation81
You want a turret / slewring bearing, and many have teeth on one ring, which is better way to drive with it.
Or turntable bearing, but probably not a good idea if you consider wind loads.
You'll have to list diameters and weight for any useful recommendations

Reply to comment by OfficialWireGrind in [OC] English Words of Spanish Origin and the Number of Mentions in Wikipedia by OfficialWireGrind
Adobe 1739, American English, from Spanish adobe "unburnt brick dried in the sun," which is said by 19c. Dutch Arabist Reinhart Dozy to be from oral form of Arabic al-tob "the brick," from Coptic tube "brick," a word found in hieroglyphics.
Other sources point to a Spanish adobar "daub, plaster," from the source of English daub (v.) late 14c., dauben, "to smear with soft, adhesive matter, to plaster or whitewash a wall"
canoe (n.) "light boat propelled by hand-held paddle or paddles," 1550s, originally in a West Indian context, from Spanish canoa, a word used by Columbus, from Arawakan (Haiti) canaoua.
French, from New Latin canoa, from Spanish, from Arawakan, of Cariban origin; akin to Carib kana:wa canoe. First Known Use: 1555. The Spanish spelling finally settled down on canoa about 1600.

But in both of my examples it wasn't any Spanish speaking country, but Spain that took a native word like for potato.
And if you are doing word origin, yes most Spanish words came from Spain.
But this is silly because almost all these same words were adopted by French before becoming English words.
So why the fuck are you arbitrarily stopping in the chain English French Spanish (some Caribbean language)

No it doesn't..
>And the Spanish acquired it from the word "kana:wa", used by the Arawakan indians of the Caribbean islands to describe their boats
Yes, there is a Spanish word and French word that ended up in English, but canoe isn't Spanish.
Same with potato. Taíno is an extinct Arawakan language that was spoken by the Taíno people of the Caribbean.
You are using stolen words from colonial Spain, and pretending they are Spanish that ended up in American English, but they were words for stuff they found in the Americas and their native words.

Again you need a third wire to do so. In the short term of there is cold water pipe nearby, wrap bare copper around it and connect to romex ground copper.

There is no amperage loss. It's not a thing. There might be voltage drop and arcing.

No. The box is nailed into wood. The k&t come through wood and insultators and there is no metal conduit all the way back to the panel. So that would be crappy ground.
If grill is outside you could hypothetically put ground rod in ground for that outlet, but not really correct or to code.

Lights never had a ground. Knob and tube obviously never had a ground.
What are you even asking? You either run 2+ground back to panel or don't. It's pretty obvious. You will have ungrounded outlet in the mean time.
derphurr t1_ixzo4rc wrote
Nope, that's the entire end of the joist, which is supported by that wall.
You could probably notch an opening in the wall and mount projected on opposite side of wall and light goes through opening.

Pharmacological therapy mainly relies on the administration of artificial electron acceptors, metabolites and cofactors or oxygen radical scavengers (Dimauro et al., 2004).

Most patients with mitochondrial disease are inactive because of exercise intolerance or fear for muscle damage, in spite of the fact that aerobic training increases work and oxidation capacity in these patients (Taivassalo et al., 2001; Taivassalo and Haller, 2004).
