The second one in each row. The top row 2nd for the office, the middle row 2nd for the living room, the bottom row 2nd for the kitchen.

Where ca we try them?

Do they make picnic tables?

I built a glorious table for our back yard once. Tiled an entire 4x8 sheet of plywood. Did not cover it in the winter. Water got in the grout and ruined it. I should build a replacement this summer.

We bought a picnic table at Home Depot. The frame was quality metal. Removed all the warped cheep wood. Replaced each piece with 2 pieces of thick (pressure treated) lumber so everything was double thick! Used 36 bolts throughout the double thick lumber to make sure they stay flat forever. Kids applied art and handprints. 2 coats of polyurethane.

Nice!

I was thinking of making a concrete slab table.

How big?

I think I know what you mean, have seen some very nice concrete countertops.

Something like this but maybe thinner:

It needs the thickness for strength. Also make sure to use some reinforcing structure because concrete is excellent for bearing a compression load but terrible at holding up the edges away from the legs in the center there.

I don't know if I'm explaining it since text sucks for communicating things. If you were standing here I'd be using my hands and maybe some props to help.

Eventually the legs would be standing long after the table surface cracked and broke off. Hence the use of steel rods inside most concrete structures called re-bar. This might be obvious but, "re" is short for re-enforcing.

If you look at a dam it will be built leaning into the reservoir. If it was vertical is would break under the pressure right away. The shape directs the force in a way to use the concrete's strength.

Basically it's very difficult to squish concrete and much easier to pull it apart. Those edges won't support themselves very well.

You could put a truck on top of the legs but karate chop the edges off.

Always check your insurance before any Cobra Kai on the concrete.

That series on the Netflix kicks ass, pun intended.

I don't love Wikipedia but Google takes me there and the preview had a couple of words .i was lacking.

So if you built a steel frame with a corrugated metal base under the table top it might out live your grandchildren. Another way would be to shape it so it looks a bit like inverted pyramids on lower legs. I'll see if I can find a picture of something similar.

Inverted pyramid table sounds cool

Now you need to be careful not to build something that will fall over too easily.

Make the leg tops kind of like these upside down.

Also you might want to make the legs an extra third longer below grade to avoid the tipping hazard we brushed on with red wanting an inverted pyramid table.

If he doesn't know how TF concrete walls / floors / slabs are poured, he has no business using it

Similarly, if he doesn't know WTF rebar is, or what it's short for, or what tie wire is...

Then stick with wood.

I used to work at a precast plant. Those fake marble tables that you see outside of places like Burger King, I probably poured 1000 of them.

Plus the concrete table looks nice and he would not have been the first person to make up some molds and pour one that would most likely last over a year.

I'd rather attempt to help the guy out than tell him to go lay down and hire someone qualified to make everything for him. How is he supposed to learn how practical things work if he does not get his hands dirty?

We're not all super wealthy and can hire the Italian guys to come out to make a table for us.

Finally if he does not learn about the structural basics he risks hiring some "professional" that "has no business using it" to do it and charge him money.

Thanks for the pep talk betiko!

In his defense often at a construction site more than half of the people should not be allowed to touch basic hand tools. And I agree they shouldn't be there.

Some of them are merely inexperienced but some have journeyman trade certificates.

The worst is when they are the boss. Fun times arguing with a guy that will be firing or laying you off later because they want you to do something wrong.

So back to our chat...
Look ma, no re-bar. https://www.nationalgeographic.org/ency ... aqueducts/

They didn't even need computers or smart phones to build aqueducts. look at the arches, they direct the forces so everything is compressed.

I was also thinking of flying buttresses. Inside the ceilings of large cathedrals are constructed in ways using arches to bear the load of a roof made of stone. You also will notice windows in brick and stone buildings used to be round at the top, same reason.

Upon googling "flying buttress" I learned a new word, "catenary" from this guys video about the external flying buttresses on the outside of those giant old stone cathedrals.

Trying to save you some pain, ya prick! Compare me with that french f*ck....if I had a rubber hose...

You know I love your Bible thumping ass, Yosh-monster

Don't blame me. I am a lost cause that doesn't know a carrot from a house.

That was at Yosh ya Hoser
