@JMF, and others:
Try a Calcium with minerals tablet, 500 mg Calcium, Vitamin D3, Boron, Manganese, and other trace minerals.
And of course Vitamin B Complex combination.
Sunlight is needed to absorb Vitamin D, which is a very neglected aspect of health care.
Half an hour of weak or 15 minutes of strong sun, or alternately artificial source, 4 times a week, prevents a lot of issues.
Way off topic, no offense intended.

It does not leave you out, but having above average arm strength, makes one more susceptible to abuse and lift dangerously heavy loads which persons having normal and below normal strength do not even consider of lifting.
You're gettin waaay too serious (granted, good messaging)...
I've training in all kinds of back safety, ladders, 90 foot man lifts, compressed and cryogenic gases, lasers, handling lead and beryllium, NEC update training for 2020 edition, and gobs more...
In all that, the most important thing I learned is... Hire somebody else to do it. My takeaway in all that training, is the well worn verbage.....""no user serviceable parts inside....please refer servicing to qualified personnel"". I can only hurt myself...
Picked up two 4 by 2 sheets 1/2 ply, two 1/4 ply, one 3/8 high density MDF for router templates..130 bucks... Man, this "supply chain" price gouging stuff sucks.
Full sheets have a bigger footprint than my car, so I'm stuck with quarter sheets.

JN,
Delivery? I think my plywood wholesale supplier delivers free above $200. Of course when it is delivered I do buy a bit as I have storage space.
I also buy the 5’x5’ Baltic birch plywood. Easier for one person to handle. Trivial to cut with my big sliding table saw.

I too can get free delivery over 200 dollars. Problem is, I can't get a 4 by 8 in my basement, not even a 5 by 5.
I thought there were problems getting baltic birch now. I settled with BC sanded, the only thing my HD had.
John
I have a neighbor with the size problem. He gets the larger sheets to his open back porch and cuts them to size there.
I find the Baltic birch is occasionally not available in a given thickness, not just across the spectrum. But there are three main producers for the birch with Russia being one of them, so those who were using that source probably are having supply issues. I have found that only the Chinese source birch plywood was of lower quality than the Russian. So I avoid both of them. I don’t find HD around here handles any variety of the Baltic birch plywood.
My usual limit on plywood is my forklift doesn’t really want to handle more than a ton or two at a time.
My steel supplier knows this and packages my steel orders into single ton bundles, no matter how much the total weight may be. The upper limit is the flatbed delivery trucks also have a load limit.
When renovating my place I did specify stronger than normal concrete for the floor. Some of the slabs have moved slightly, but only minor crazing.
My 6” asphalt plus base parking lot was damaged when someone mistakenly delivered a 90 ton piece of railroad equipment.
The other interesting deliveries are from Amazon. Their drivers like to just drop stuff off in the middle of my parking lot! Some intended for me other stuff for neighbors. Last time was this past Friday at 5:45. My instructions are we close at 3!

They are building a new building just outside my office, an endstation for an x-ray beamline. It's interesting watching them dig and put forms in place. Apparently, the endstation equipment is heavy, and there is probably some king of vibration requirement. So there are quite a few 6 foot by 6 foot concrete forms setup now in the middle of the building footprint, I guess pads to support the floor.
I was not aware there were three sources of baltic birch, nice to know.
John
Are the X-rays aimed at your office?
My turret punch bangs away at as much as 35 tons per punch and rated at 200 punches per minute. However as it also has to move the material, a Big Bang punch probably runs as low as 30 a minute. Good thing it spreads the floor load out over several square feet of the concrete floor.
I was once punching 3” holes in a sheet of off specifications stainless steel when the punch failed to go through the sheet! I resharpen the punch to have a concave surface. That increased the force on the periphery and allowed the punch to work. The downside was much shorter punch life.
My normal steel has a yield strength of 30,000 PSI +/- 5%! That tight tolerance is needed to make sure all bends are the same. If you think of a 3” hole that is a 9”+ edge or 270,000 pounds + of force to punch through a 1” thick piece of steel! That is why I rarely use sheets thicker than 1/8”.
I estimated the off specification stainless piece exceeded 250,000 PSI. A friend who worked for the navy on gun barrels was used to 200,000 PSI or more. Normal structural steel is calculated at 10,000 PSI. It really runs 15,000 to 18,000 PSI. Thus mistakes in designing buildings rarely has nasty issues.
Sorry if this post was too educational for some folks.

No, I am trained in Metric, that means an extra thought stage.
Vibrations are a fascinating topic in construction.
Here thick concrete pours are done with ice instead of water, prevents cracks, as the cement and water reaction is exothermic.

@simon7000 Ed, I am very disappointed you don't have stonemasons on side as well. I thought you were a one stop shop 😛
An old saying: In life there are two types of people, those who move heavy things and those who say "Hey, you - go move that heavy thing!"
Having earned a living as both, I have my preferences.
I design all of my projects in SketchUp, after I have all of the major parts of the assembly detailed, I do a layout of those parts (where made from sheet goods) on the full sheets leaving adequate margins for cutting between parts and looking to minimize material waste. Then I identify the minimum number of cuts to the sheet needed to allow it to fit in my vehicle and down my basement stairs. The sheet good supplier I work with isn't the cheapest but he's happy to cut the whole sheets matching my instructions. It's usually two cuts per sheet, sometimes three. Here's a recent example for a project out of 3/4" walnut plywood that was running $180 a sheet.
Bill,
One of my fellow I met managed a Jewish temple. They had a problem with some of the marble stonework. He was involved in getting the problem repaired when the stonemason doing the work brought in some substandard marble.
He told the stonemason the marble was unacceptable. The mason took offense at that and used the line “What do you know about marble?” To which the fellow explained as a concentration camp prisoner during WW II he had been slave labor in the marble quarries and not just knew about the marble quality but could even tell where the marble was quarried. He still had his concentration camp tattoo on his arm.
So although I may know a stonemason or two, it is not really a popular trade around here. Also most of the work around here is brick or concrete block.
My building uses concrete block, some of which are old enough they have the patent identification molded in.
Code:
while (1) {
printf(
"LOL,
LOL,
LOL,
LOL,
%s\n",
strerror(std_err)
);
};Sir, you are expecting too much. I humbly advise you to lower your expectations.
This is Ed we are talking about... he puts most of us to shame with what he can do in his workshop
Bill,
Anyone can match my shop capabilities with about $500,000 worth of equipment.
By the way my rule is whatever machine or tool you buy, to have properly paid for it you should have processed material worth at least ten times the cost of the machine.
It did take me two stadiums worth on input, output and tie panels to pay for my most expensive toy a Nisshinbo turret punch.
My Felder panel saw is the exception. Although I have certainly passed the material cost test, it was purchased to decrease the likelihood of having fewer than ten fingers. So far, so good.
As I tell folks my shop is small, it is only half an acre.
However shop skill wise I am still looking forward to always remember which end of a soldering iron to hold.

Actually, yes. However, they said the beam is 30 keV energy. I asked if that could be blocked by aluminum foil, they said yes.
So now I will have justification for wearing my tinfoil hat...
