Welding/Fab Table
Now that I have a metal brake to build in order to build a storage cabinet I now need to build a half decent welding/fabrication table. My knees are getting too old to mess around welding things on the concrete floor!
Many welding tables have 5/8" holes at 2" centres for clamps and various other tooling. Is there anything special about the 2" spacing? It seems quite close and means drilling many many holes. Would there be anything wrong with using 75mm spacing? I realise that maybe some of my clamps might need to have an additional 1" of reach. There is a huge difference between drilling 1,081 holes versus 465 in a 2400x1200 table.
How big a table do you guys and gals have? It would be nice to have a table 2400x1200 to hold a full sheet of steel but bigger is more costly and takes up more space. Do you get away with smaller tables? Do your tables us the locating holes or are they just flat?
Thoughts are welcomed.

Mine is 1800x900 (give or take, can’t remember the exact measurements off the top of my head), grid of M12 threads on 100mm centres. The top is 30mm thick ground both sides, weighs around 500kg or so. Consider selling it if you are interested, I’m giving serious consideration to down sizing to around 1000x600 with a 12 or 16mm top, grid of M12 at same hole centres. I use the M12 because it’s sort of become the default standard in my workspace, so everything is interchangeable. I use the clamps off the mill on the welding bench fairly regularly (way cheaper than using 16mm holes and tooling up with Stronghand stuff).
I’ve had numerous variations on the welding bench theme over the years, I’ve not made one single thing that has required me to be able to put a full sheet on a table in 30 years of making stuff. If I needed to now, I would simply make some some outriggers for the bench I have. Most of the time I only work on 1/2 the table I have.

Hi Mk 1_ Oz
My belief is that a fab table should be first project off the rank for anyone who has purchased a welder for fab purposes.
A welding /fabrication table should be built to suit the needs of the person using it.
It gets back to individual choices .
Not necessarily ranked in order of importance-
Frequency of use
Type of fabrication
Physical Size of fabrications
Suitably of your own hold down tools-cheaper than the custom ones that come with a kit.
Budget
Available workspace-consider Mobility,storage and a multi purposing of said table-when not fab use.
At this point you should have some idea of the items you desire to fabricate.
Personally. I have never needed more than a square meter to achieve what I have had had to make and the few larger items -Ie meshed door frame were accommodated by using other mobile tables of the same height arranged side by side or slightly apart.
That,s my cents worth.

It does not matter what size table made there are times when its not big enough.
I remember in the fab shop days the table were 2.4x4 meters and we joined two together to get the size we needed.
My home table is 1500x900mm with 25mm top plate and is more than large enough for the work I do. In truth it spends more time as an assemble bench than a welding bench these days.
A couple of years ago I decided to drill and tap some 120 5/8" holes on 100mm centres. The jury is still out on whether it was a good move. It was not that hard just to tac bits to the table and weld. Now I spend more time looking for nuts and other small bits that have fallen through the holes.

Thanks
I just asked this same question to Bollie the other day of what his thoughts where.
I have a piece of 10mm here 1500x560mm and a 75x75mm heavy wall stand I'm going to marry together.
I was either thinking 1200 or 1000mm long.
For my shop the smaller is better.Using Tapatalk

Working space.
I wish I could remember these things and get them in one post but as I have just tripped over my shop vac it brings to mind one thing, working space.
My table is 1500x900mm. The back is up against an object so there is no room there but it still means there is about 3100x 2000mm floor space taken up.
Just a thought.

Mine is only a small table - around 1200x600, with 16mm steel top.
Its on 150mm cast iron wheels at one end, and has retractable castors at the other end so it won't run away by itself. It lives against a wall under some pallet racking which forms a shelf above - but I can move it out into the workshop further if I need to work around it more.
Its really just a general welding table and not a fabrication table though, so doesn't have any fancy holes or clamping functionality.
The legs are set 60mm in from the edges of the top which means I can edge clamp most things, and I tack bits of scrap to the table to create stops or clamping surfaces if required.
Tony makes a good point about working space. With a small table like mine you can reach across to the other side. If your table is 1200 deep then you have to have access to the other side or its just dead support space. Means it can't really live against a wall since even if you're not using the other side you can almost guarantee that you'll need to get to it to retrieve that piece that rolled/bounced just out of your reach.

What do you all find works height wise? Sitting height, standing height or adjustable?

Mine is currently adjusted for a metre (I’m not quite 6’), I have a bolt on/off stool outrigger if I need to sit and do lots of small fiddly parts

I have a 2m x 1m Stronghand set at 930 deck height. For me that's worked out to be the best height for standing welding, it saves a lot of bending over. I also have a high rise gas lift chair that I use for sitting TIG jobs.
The under bench area comes in handy for storing clamps and other welding bits and pieces.

The table top is made up of slats with 16mm holes at 50 mm centres - they take the de-facto standard insert clamps - but they also have 40 mm gaps between each slat so you can run clamps in on sliding blocks if the pre-set positions don't suit. PM me if you want to have a look to get ideas.

Mine is about 920 to the top surface. Works well for me both standing and also when sitting on a stool for TIG work.

Mine is 930mm. Seems to be the best average for standing where I can reach over to far side comfortable or sitting using the gas strut adjustable chair. Strangely enough the last time I was sitting and welding two milk crates were just the right height.
OxxAndBert mentioned 150mm wheels. I like big wheels. Bigger the better. With 600kgs to move around I found 200mm wheels make life much easier.
