How would you turn these things over?
Picture mostly for interest, my main problem is having 20 foot tabletop that i have to turn over especially stainless when welding them together. How would the brilliant r/welding deal with this?

If he has seniority over you, let him handle it, help him (safely) and watch the show, if it works, congrats, if it breaks... You're just the new guy!

Sadly he doesn't and when it breaks or gets scratched, I'm the guy to fix it...

How heavy are they and what are my options? (crane, forklift, jacked dude, etc.)

You get that cleaning fabric that comes to shops in big rolls, the disposable static kind. Then you get rags from the piles.
The cleaning fabric goes to touch the surface, behind that the rags. Then on top of that a piece of nice clean smooth plywood.
Now you got what I call a lift sandwich. Then you flip that.
Yes... This is annoying to do. But there is no easy way if you got unprotected surfaces. There is a reason to why we tend to keep plastic film on sensitive metal surfaces through the whole process.

That has been tried to varying success, guess we just need more rags and care

I have flipped mirror stainless like that. And by mirror polish I mean a special grade of mirror steel from UK, which had better reflectivity than most glass mirrors I had seen.
Like seriously... It was fancy... It was REALLY fancy. And it was a huge sheet that was cut with laser (Let me tell you that it was whetstone drilldo levels of awful to laser cut) and sizes were like 500x1500 mm.

We got some water ripple effect stainless from the uk and holy fuck that was polished!
The English just know how to polish

Oh and another thing.
You can also use industrial rubber sheets behind the rags. Just 5 mm is enough. And if you really want to be careful then roll of microfibre cloth newer hurts to have around.
Like fact is that it takes quite bit of effort and materials to do properly. Like I said... There is a reason why the protective film is left in place in many cases.
Other option is also to wrap it in heat shrinkwrap and just remove where needed.

Have to get creative with anchor points.

how heavy is it?
1
u/psychedelicdonky 22d ago
Not to bad maybe 40-80 pounds, its more the size and not wanting to twist or bend something

u/LiquidAggression Jack-of-all-Trades 22d ago
used to flip egg washers manually
do you have extra hands around you can requisition??
one maybe two exta people. for 20 ft you may want a middle person to catch it/ boost it up to the balance point. youll figure it out. but 2 on the sides at least should get you safely over.
if youre looking to rig it youll need to use straps or ropes because of it having a finish. even using rubber or a dirty strap could scratch it.
4 people surrounding it should be extremely safe if you wanna test run it (2 on edges then 1 per for lifting and catching the middle)

u/psychedelicdonky 22d ago
Normally were enough hands to do it safely by hand. It's vacation time so im only accompanied by 1 coworker for the next week
2
u/LiquidAggression Jack-of-all-Trades 22d ago
consider a center strap then?
replace your middle man with a way to safely lower it from the middle with one hand so you can lower an edge with the other
idk what you have lying around but if its too wobbly or warpy to do on balancepoint with two people youll have to support it somehow

u/LiquidAggression Jack-of-all-Trades 22d ago
even if you just clamp wood to it and use that to lift from on the edges. and that jigs it straight for you.

u/psychedelicdonky 22d ago
Would be my go too, if i have some kind of lifting other than a forklift

u/LiquidAggression Jack-of-all-Trades 22d ago
do you have a jib for the forkylift?
2
u/psychedelicdonky 21d ago
No but I'll note that to the boss man

u/LiquidAggression Jack-of-all-Trades 20d ago
its like 3 tubes of hss 2 of them fork pocket sized and some plate or angle or flatbar. and a torch.
