Metal Workbench Top Over Particle Board

[Lionelgee]

Hello All,

I bought one of those workbenches that are made out of pallet racking last year. The bench will be used outside without an cover over it. I would like to put a metal covering over it so the particle board is protected from the weather. It would also be good to use the bench for welding to.

What type of metal sheet and thickness would you use?

Would your specifications include using a galvanised sheet?

The workbench has two layers of particle board. The first forms the top of the bench with some overhang past the pallet rails. The second layer of particle board is a shelf that is cut flush to the pallet rails.

Kind regards
Lionel

If you’re going to be welding on it, then the timber top will need to go - getting a piece of sheet metal folded along 2 edges to fit over the frame would be the go then you’d be able to get away with something quite thin - maybe 3mm. If you wanted to do heavy stuff in it or want a plate that was self supporting over around 600mm, then at least 5mm thick, which will be expensive. Again, if you’re welding on it don’t go for anything galvanised.

You'd very rarely need to weld over anything like the full bench top. I'd use a timber bench top and if needed have a small metal plate (either temporarily lifted in to place or permanently up one end) to weld or do heavy stuff on.

We have found that light metal benchtops used as welding benches end up warping from all of the weld contraction on them. We have pretty solid welding benches now (well, 12yo now), I'm not sure what the thickness is, maybe 6mm and they have been fantastic as 2400x1200 welding benches.

I would just buy plate to replace the timber if you're going to weld on it.

A nice piece of 16mm will do the trick (jokes)

* I say 16mm because I have it sitting here at work

Was going to suggest that as a mates workshop has a 16mm steel welding bench and it's brilliant. Think he paid $200 for it from an auction lucky sod...

Probably better to have a separate welding bench, I inherited one of these (supplied by Hare & Forbes).




Previously the father-in-law had made his own from a couple of pieces of thick plate, some lawnmower wheels, a scissor jack (for raising & lowering the wheels) and whatever pipe/angle he had laying around. It used to have an antique stick welder mounted underneath.
This had been used for many years and I still have it because it's handy to move around to where I'm welding.
The handles for moving it swing down out of the way and there are lots of holders & brackets for goodness knows what, probably 'continuous development'.

Pic, Plasma,oxy and TIG welding table.The circle table is held on with one clamp and is only put on for cutting circles.The tile is a 2 feet X 1 inch thick zinc alume clad millboard that just sits on if needed.They are a throw way item as I have have several hundred if any body wants some

That's a very snazzy circle cutter AM

I wouldn't be relying on particle board outside. It will suck up the moisture like weetbix. Replace the chipboard with some decent thick planking.
