Workbench design help needed...

Hi all,

I want to build a workbench for the garage, plan is to make it of angle iron to hold a wooden top, with a angle iron frame just above the floor to hold a shelf. Legs would be square tube welded to the underside of the angle iron holding the top. The shelf would be welded to the internal faces if the legs. Total length 2400 mm, depth 700. Plan is at the moment to have a leg at each corner and one front and back in the middle to support the span.

Couple of questions... Can anyone suggest wall thickness for the angle and the tube? Also, any obvious improvements?

Cheers

Chris

thought about putting a back on it?

stops bits falling off the back, gives you a nice area to hang tools and add small shelves for bits and bobs. And you can also add a shelf on the top of this.

make a reinforced corner to bolt a vice too.

add supports under the work surface front to back quite often along the length of it to stop the surface sagging (even thick wood will sag evetually)

cupboards are always nice to keep power tools in underneath too?

as for steel thickness, 3mm angle would be fine, 1.6mm box also fine.

I used 50*50 *3mm box for my workbench. Also bought and fitted some m12 adjustable feet from ebay. They aren't fitted when I took the pictures. They allow you to adjust out any shoddy workmanship and if you do manage to weld it perfectly square you will probably find your garage floor isn't perfectly level anyway.

Mines a lot smaller than yours but it is nice and heavy. I would like a heavy steel plate top for it but funds dont allow.

I built some benches about 15 years ago for my workshop. They are all 2400mm long and 600 deep. Made them from standard 25mm box with 18 mm ply tops. A leg in each corner and central ones at front and back on the long runs. Held to the wall with a couple of screws to stop them moving around.

I have a large pillar drill on one and a hydraulic press on another and a big record steel vice above one of the centre legs. They are great, plenty strong enough to drop an engine or gearbox on.

Scrap tube and old tennis court fencing angle, I guess 6' long and 2' wide bolted to the floor and wall with 1" thick MDF flooring dropped in the angle recess.

It's also braced where the large vice sits, because its bolted I can really swing on the handle of the vice.

Completely open at the front so I can roll my welder trolley, power hacksaw etc underneath, I also have a couple of wheeled trolleys which other stuff sits on.

If you are planning to drop the ply on top of the frame then get some thin angle and screw along the facing edge, this allows you to bend stuff and stops the wood eroding and chipping.

I used the build board and some 2x2 after I made my chassis

I haven't decided on the new one yet

I built mine using NEW kitchen units and worktop.
Plenty strong enough and storage benefits

I'm planning a bench for my new garage. Will be 40x40x3mm box legs and 40x40x3 angle top and shelf with 25mm MDF work top and shelf (the MDF was salvaged from work and free otherwise I'd be using chip board). I'm on the look out for some steel plate for the top to make it suitable for welding as well.

Same here. Wickes were selling some butt ugly carcasses for a bargain price, something like 12 for a double and 7 for a single. And there's a place near me that sells seconds worktops (mine had a chunk missing out the back), so I was all sorted for about 30.

As Slimey says though with a "seconds worktop (dint one end that was cut off anyway, the whole lot cost less than 50 and was up in no time

I built mine from old kitchen units and used lengths of 6" x 2" pine, fastened together for the work surface. Plenty strong enough and great for storage too. Only problem is...... my workshop looks like a kitchen..... Think I need to paint the cupboard doors dark grey

I threw this together last year from some pilfered scraps and a few pallets, cost me nothing but screws, since then I've screwed all the boards on the top together.

Not quite as strong as I'd like, but I can jump up and down on it without any problems, so it'll do.



(Excuse the sprog's contraption, I don't even know WTF that was)

I think the most important thing with a workbench is that you make it heavy enough or secure it well enough so that when you put something in the obligatory attached vice and attach a scaffold pole for leverage that the bench does not move when you apply the required force.

I was tempted to make mine from steel, but went with wood in the end as I had some suitable 2" x 6" offcuts. It's also now a semi-structural part of my garage! This is the frame of mine, which is 3000mm long and 630mm deep:



The frame was then topped with old kitchen worktops, which are always available cheaply, and then the whole lot was topped with a galvanised 3mm steel sheet, bent to suit by my local trailer builders. They also happened to be the only local place with 3000mm long sheets. The steel sheet is stuck down with 3 big tubes of contact adhesive to stop it ringing and then screwed to the wall and the front face of the bench. I can jump on it, swing on the vice etc and it doesn't move at all. Including the top, I think I spent 120 or so on it. It's perfect for me, but a mate finds it too high to use. But then I'm 6'3" and he's not. It's probably the best money I spent on my garage.







Let your plans be dark and as impenetratable as night, and when you move, fall like a thunderbolt.

Mine was built from an ex m/c pallet. It was 16' long. So I made a garage bench at 12' and a garden table at 4'. The top was 2" x8" timbers over 6"x4" timbers. Cost nowt . The garden table is strong enough to take an engine for working in the sunshine
