Purchased a new NiCd razor. It has an old-style external (1.5 volt DC wall plug-in/cheap Chinese) charger/inverter.
No apparent "controller" or regulator like the more modern LiOH batteries and regulators.
Will I gain anything useful by fully discharging it to 0.0, then recharging? Or just...
Snap is "off" Grids are "off"
OSnap defaults are Cen, End, Insertion point (for blocks), Intersection. I really don't want to continually change these either.
But. When I run a line (or dimensions, or move a point to a new point) particularly when in a complicated area with a lot of...
I have 4x 3/8 dia carbon steel setscrews holding each of 13 CS rings in place in an outdoor setting. (Low stress, but the surface rust and subsequent streaks are irritating.)
The CS centerpost itself and the 13x rings are spray galvanized with a commercial topcoat, and the rest of the post...
I was informed by the GA Sec of State Office (via a voice phone reply, no other letter, no email) that the older GA PE on-line renewal website is no longer available.
The only GA PE registration/renewal point is apparently now:

Several steam power plant turbines have been destroyed recently - and the number is growing as long term maintenance funding is cut while older plants are kept in use.
Clearly, if the plant is rebuilt from the original drawings to the original positions and supports, and when all support...
Seen this many times, but have never heard an explanation.
The outlets of the cooling water foam up with long-lived, "heavy" foam (not a light froth. Outlet is (of course) warmer than inlet water, but river water, lake water or recirculating water to cooling pond all seem to show the foaming...
Few details are available, and almost every on-line link and associated photos I find refer back to the May, 2017 Hwy 1 collapse at Big Sur that recently finished rebuilding/re-routing, but the California Coastal Hwy 1 was closed south of Monterey CA due to new mudslides Thursday (28 Jan 2021)...
On a different forum, a question was asked that has me puzzled:
User asked how far an object would be blown sideways in a 4 m/sec westerly wind if dropped from a 280 meter tall building. Turns out it was not a "college physics homework question" at all but a dropped object safety review. Guy...
Installing a series of 3/16 thick carbon steel stair runners. On gates and railings, I usually weld up and then wipe them clean with a paint thinner to remove mill scale and oil, then cold spray galvanizing paint on the metal. Then finish with two oats of black oil-based paint as a cover...
Fluid = Hot fuel gas at 410 Deg F, modest pressure (about 225 psig). Flanges are insulated with wrap-around pads, so they are not watertight, not under a solid sheetmetal cover.

We are replacing the B31.1 saturated steam piping from a competitor's existing turbine casting.
7x flanged pipe connections from the turbine are built up from the turbine with "standard" ASME pipe flanges welded to pipe stubs welded to the...
Vendor (a competitor) is quoting NEMA SM 23 limits on their new turbine nozzles to replace a unit that crashed a few weeks ago. As you would expect, those very restrictive turbine nozzle forces and moments are causing extreme cost and material increases in the replacement steam piping, pipe...
Design conditions: Main Steam,
Service conditions: 450 psig at 905 degrees F.
Design conditions: 981 F at 1881 psig.
Pipe: 16 inch OD, 12.5 inch ID, 1.75 inch wall thickness to re-route and replace an existing main steam service pipe to a competitor's steam turbine that crashed.
One of my...
We are calculating substantially different nozzle movement (hot position of the turbine bleed and inlet piping nozzles) for a repair on an older competitor's turbine. Not many original vendor prints and no engineering design analysis documents readily available.
In particular, our calculations...

The government's NSIDC (National Snow & Ice Data Center) has changed hundreds of Daily Sea Ice Area and Sea Ice Extents values for 2016 and 2017, but they've not said why, nor what records have been erased, and what records have been changed.

It might be my rusty algebra, or my even slower Excel, but I have a question:
If cell [g308] "= exp^(f308)", then its inverse (in Excel) in cell [h308] is "= LN(g308)"
and cell [f308] is going to equal cell [h308]
If cell [p308] "= Log(q308)", then its inverse in cell [r308] "= 10^(p308)"...
I frequently need to document very small flaws in very tight, very poor lit spaces: small scratches, weld cracks, tooling nicks or flaws, thread cuts, nicks or as-found damage for the clients' records, for final reports on repairs or problems, for engineering evaluation back in the office when...
