No shade thrown. I have a clean hard hat for pictures, and a real one for work (fits better, tighter to head, and is less likely to fall off). My past life involved a great deal of these folks that would show up for pictures, and then left when the real work showed, usually after a fire, train...

Call me cynical, but I doubt these folks have any hard hats, work boots, or gloves, of their own. They are probably the PR crew. Available for pictures, but not much else. I'd rather see cranes/jack-up rigs moving to pick up this mess. And, its a big one (mess, that is).

I have a pretty hard hat for pictures. I have a well used one for, well everything else.

Gotta be honest. New hard hats don't give me the confidence level that well used hard hats would.

Wow. A lot worse than the crawl on the local news was describing. I think the article said there were two pilots on board.

Welding Metallurgy, by Kou.

My favorite part of that scene is when Chewbacca pushes on the wall to "no avail" it is pretty clear he's moving the wall, or at least slowing it down. Probably was tough to film that on the budget they had.

I don't believe any common stainless steels (304/316/18-8......) will matter much. Not knowing the contact time, temperature, or concentration makes this difficult. First thought is to maybe going to a higher nickel alloy will help. Seems Carpenter 20, and one of the Hastelloy's are alloys...

I've had one like what you have, and mine was smoothed mortar, rather than a beauty strip, but I didn't do that, myself, and it looked very nice (probably because I didn't do it). The mortar/grout was slightly rounded at the edges. I believe they laid it and waited for it to mostly set. Then...

Can you find a piece of trim that will cover that raw edge, and not be an eyesore? Something like 1/4round would do a pretty decent job of covering that, if the clearances and dimensions work, but it looks like the root will be filled and foil any attempt at a cover. You may be able to use a...

I would seal the grout, and use caulk in the corners or at joints, where there may be some expansion/contraction where the tub/shower and the walls/trim meet. If you have gaps, you may be able to use some trim pieces, like 1/4 round, either polyurethane or PVC that won't really have an issue...

Not my favorite, but I ran weedeaters and bushogs at a rocket motor plant to clear the grass off the bunker/berms over the control areas. I'd call it a learning experience.

An anecdote---my wife tends to get bothered by minutiae when I make a purchase she doesn't agree with or didn't know about. "Your new mower smells like gasoline and makes the garage stink" is something I've heard before, and you can insert "pesticide sprayer", "weedeater", "diesel generator'...

Or because it is not being felt/perceived. The presence of safety equipment to moderate the perception of speed, reduce vibration, etc., definitely hides some of this. May be part of why speed perception in a boat, or an open cart, seems so much greater than in an enclosed car, or why a...
