Building a new welding and fixture table for my tiny garage, and even with judicious space maximisation it can really only be about 900x600. That said I dont want to spend huge amounts on it and so doing things so that it can be as flexible as possible.

I considered just picking up a Certiflat welding table, but after looking at them they seem a little flimsy for some of the other uses i was thinking of for this table.

A local steel store was basically giving away some lengths of 150x10 flat bar, and i picked up some 65x65x6mm RHS to go with my 50x50x3 that I have been using for the machine stands. Planning on using the 65x65 as a receiver for mounting tools on, in the same fashion as a trailer hitch, only vertical. Main tools will be a 6" offset vice, bench grinder and a handful of other tools that need a convenient receptacle.

Came up with this design for the table in a rather boring afternoon conference call:

Havent locked down the height yet, but probably something around 850mm overall.

The framework under the flat bar top uses 50x50x5 angle iron to support the flat bar and tie the legs together. The flat bar will be secured to the angle iron using M10 countersunk socket screws, and designed so that they are replaceable if needed. Im undecided about putting a pair of smaller braces across or under the middle, but may end up doing that to just reinforce against sagging.

Feet are standard hockey puck feet with M16 thread for securing, and I will probably also put an M16 jam bolt on each upright to add lateral pressure to the receivers.

Fixtures will be drilled on 3" (75mm) centres, which I think is a good balance between having enough points of contact for fabrication and strength in the plates.

Any suggestions?

Are you drilling through holes or putting in threaded holes? A combination of both is worth thinking about. Do you have a milling machine or thinking about getting one? Matching your weld table to your mill hold down kit allows your to get double duty out of your hold down kit.

Abom79 has a set of videos on making a fixture plate. The holes and hold downs are just as applicable to a table like your building.

Check out this,
Which is part 7 of the build and then watch part 8.

where you are can you get a certiflat for comparable price? i got one. its ok. i can hammer on it and it is flat but if i was going to put receivers on it i'd add steel to the sub structure and not the tab and slot top.

This is a small garage and should be multi purpose. Get a simple flat top so the bench can be used for other stuff, have some overhang to it so you can clamp work to it. That **** is fine for a dedicated job shop with space for it, that needs it and has work.
I don't have one, don't care for them, don't want everything set on it, spilled on it going thru and want to use common C clamps and 11R vise grips. I don't care for a platen for general work. Ideal is a simple flat bench and another place/bench for a vise I can reach with the welder.
Point of pic 1 is,,, same universal or common clamps used on most everything. If this works for me there is a good chance it will work for you.

simple posts. Pic 5 hid the welding. Instead of that goofy thing at the bottom put cross brace half way up, out of angle and instead of 1 make 2 and put expanded in it. Angle is good too, can let it run inside and clamp it to weld. All square cut with this.

Will be using 16mm ********* clamps. Picked up this set cheap from a local supplier who was clearing stock https://www.machineryhouse.com.au/W08500
My mill uses 16mm slots and M14 studs so is easily able to work with this setup by machining up some spigots. Overall I think basic 16mm holes will work well for my purposes.

where you are can you get a certiflat for comparable price? i got one. its ok. i can hammer on it and it is flat but if i was going to put receivers on it i'd add steel to the sub structure and not the tab and slot top.
I looked at getting the basic 900x600 certiflat table, or the Stronghand one from Hare and Forbes down here, but they would come out to 3-4x the price of this setup for something that isn’t as rigid or able to be used for other things. For reference I’m about AU$150 in the hole on the steel for this. Certiflat was AU$490 on sale.

This is a dedicated welding an fab bench. It will be having dog holes for clamping. Plenty of things I weld are unable to be done with edge clamps.

Done this every way it can be done. Almost everything that moves or doesn't. No rockets but planes trains cars trucks racecars boats tanks tubs nuke oil coal and wood. water oil gas. Forgot tractor and implement.
The thing wouldn't make my short list if space and economy are a concern. Its not a bad thing. After doing it just found out what I like and whats easy. A little like these utv things, they kind of look cool, I understand they got more power but if I got a choice of something to work from would be a club car golf cart with a box on the back.
