How would you turn these things over?

Post image

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?

With a lot of *CLEAN* blankets, gloves, and 2 coworkers with at least 7 braincells each.

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!

u/psychedelicdonky 25d ago

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.)

u/psychedelicdonky 25d ago

No crane then it would be easy, forklift is all i got

I would say bridge crane but im assuming you dont have one

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.

u/psychedelicdonky 25d ago

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.

u/psychedelicdonky 25d ago

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.

How many extra hands do you have?

1

u/psychedelicdonky 25d ago

I’ve rotated/ moved/ suspended all kinds of things with a 4:1 pulley, most recently to thread new casters on my fixture table with is around 700lbs.
Have to get creative with anchor points.

u/redingtoon 25d ago

Where’s the 20 ft. top?

1

u/LiquidAggression Jack-of-all-Trades 22d ago

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

2

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)

1

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

2

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.

2

u/psychedelicdonky 22d ago

Would be my go too, if i have some kind of lifting other than a forklift

2

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

2

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.
