Nice that 1 inch will have a tough time warping on you, did you go with cold rolled or hotrolled steel for the planks? I built a similar table but used 1/2 inch hot rolled instead(budget), ditched the bolts and welded it to risers on top of .120 wall structural steel 2x2 frame.

I wish I had the time, money and space for a really nice welding table. I'm excited to see how it turns out.

I went with 1/2" cold-rolled (I originally had a typo above as 1").

The guy I cribbed the design from had another guy apply some structural modeling software to his design relative to how stout the plate would be.

At 600lbs, applied in 1.5" strip side-ways, the deflection would be about 1/32".

Image

In my case, I'm actually attaching my bolts farther from the ends of the planks so this potential deflection would be even less. Highly unlikely I'll ever put anything on this table that would cause any deflection.

:cool:

Last night I made some progress.

Using trusty old furniture vises my dad absconded from the Kindel Furniture factory in the '70s.
Image

One end went together very-straight with no drama. The vices held everything even as I made my strategically planned spot welds.

On the other end, no matter what I tried, I couldn't get the legs to be perfectly vertical with just the vises. I finally said eff-it and resorted to holding the metal with my hand as I laid down a few tack welds. Duh. As long as the vices were preventing gross movement, this enabled me to get as close to perfect as I think is possible. This is called learning by doing. I like it.

After assembling the base & legs I flipped what now actually resembles a table over to finalize the caster supports. I figured this stuff will all be hidden from view and thus would provide good opportunity for me to practice welding in anger with little chance of long-term visual embarrassment. I'll need to grind parts of these gap welds away so the caster scan sit flush, and I know that's going to be a PITA, but I also know I need to learn lessons the hard way.
Image

For this 3/8" steel my Miller 211 is at max wirespeed & voltage. I tried messing with different settings to get amount of popping and splattering down, but in the end I just took it as a given that with hefty material like this it's not going to 'sound like bacon frying'. I had very little splatter, but a lot more sparks than when I was practicing at 1/4" and below.

I think was moving too slow here?
Image

Looks good to me. But what do I know?
Image

Casters:
Image

I don't actually have any good grinding discs...so those are on order. I'll be using my pneumatic angle grinder... Once I get it so the casters are flush, I'll drill the holes, mount them up, and then turn the table back over. That way I can use the adjustable casters to get the table perfectly level (floor is sloped) for the rest.

Nice work, those casters don't look very sturdy, what are they made for/weight ratings?

I am truly impressed Charles. It seems like it was just yesterday that you were off to your first day at welding school.

Progress.

Got my grinding wheels so was able to grind the caster bases. Drilled some holes and mounted them up.

Image

They are awesome. Make it real easy to level the table.
Image

Image

Also drilled all the pilot holes for the plank bolts on the horizontal supports. Took my time figuring out the best way to measure and drill on the drill press. That 2nd hole looks like it's not centered, but it is..that was a mark from a previous measuring attempt. All holes are precisely 1.125" from edge...

Image

Need at 16/32" or 9/16" bit which I don't have to finish this part...

To mount the planks I need to weld bolts to the bottom that line up with the holes in the 3x2" angle pieces in the top.

I knew this would be tedious and error prone. So I devised a way of making it "rinse & repeat". Step one is to use a piece of scrap from cutting the planks to length (36") which is the right width (6") and to drill two perfectly spaced holes with a 1/2" bit. I filed those holes to be JUST big enough for a bolt to fit through (the bolts are 1/2").

Image

The lighting didn't capture it, but those two bolts lying there have had the raised lettering filed off, so they are flat on the top.

Next up was to get one end welded up. Here I marked the right depth and used the bar from above to place accurately.

Image

Then I realized I better do some practice welding bolts before I did it in anger. After a few attempts I got the technique down (my first attempt was clearly too weak and I broke a spot-weld with a hammer strike easily). Subsequent trials proved I was getting plenty of penetration and no cold welds.

Image

Using the partial jig above I got one end done:
Image

With that, I built a full jig that indexes against the end of the plank:
Image

Ta-da.

Image
Image

I've subsequently done a second plank and it all fit nicely... so I know the jig is accurate.
Image

Now just to find some time to finish the other 5 planks...

What did you use to cut all of the steel?

Since I needed to cut the 6x1/2" stuff, I begged my wife for an early Christmas present. She got me this:

https://www.amazon.com/DEWALT-DW872-14- ... =ceklog-20
Image

Which is kinda like cheating. The cuts are not as clean as the Hemsaw, but in retrospect, it's what I should have bought first.

I'll use the Hemsaw for detailed stuff. For quick cuts on big stuff the Dewalt will be my go-to. Until I get a plasma cutter, of course :-()

Nice, I had to look up hemsaw, I had never heard that before.

I've always wanted a cold saw.

I have officially completed my first real welding project. The welding table is DONE.

Image

Image

Image

Image

Some of my welds are actually respectable too.
Image

I actually went in today and cut out a few welds that I butchered. In one case it was a totally cold weld that looked like lava. I now have the hang of it.

Image

I bought two trailer hitch receivers for mounting tools, like my new vise. At McMaster Carr they sell these trick adjuster handles. Please don't laugh at my welds on the nuts. Not pretty, but I'm pretty sure they'll hold ;-)

Image

Kinda fun building a mount for the Rigid vise my son got me for Christmas. You could say it was the first welding project I completed using the new welding table! I need to get some 1/2" bolts; the ones you see here are temporary.
Image

Glorious!

Very nice, you do nice work. I'll be asking for your opinion on fabrication before you know it. I'm getting out of car building so let me know if you want me to send you referrals.

MIG = Maybe its good?


Now that you have a welding table you need to upgrade to a TIG.

I bought this a few months back:

I barely use the MIG anymore.

This weekend after making final tweaks to Maytag's suspension, instead of starting a new project (engine cradle or chassis dolly) or working on an existing important project (prepping components for the blue car) I decided to procrastinate and further perfect my welding table (and steel skillz):

Added two more receiver hitches for good measure.
Image

I decided I wanted to store stuff. So I used some 3" stock to make cross members. They are flush with the top. Yes, I know I still need to work on better penetration.
Image
Image
Image

Then I decided those lower 2x2 tubes were superfluous so I'm cutting them out. This will make the shelving more easily accessible. No pics of that yet, but I'm certainly learning the value of not over-welding on something that you may want to modify. And I'm getting quite proficient with my angle and die grinders...
