My welding table is about the same size and it works good.

The top is 3/4" steel (my son got it for free) which is the best part of the table. A nice heavy top to hammer and drill on. I would recommend looking at a thicker top.

Sounds like a good start. I lucked out several years ago and got a table from a gravel pit that had gone out of business. 1" thick 4x8 plate steel top, 4"x6" H beam legs, and it has some dragline bucket teeth welded on one end on the top that makes an awsome anvil, bending jig. Had to load it on trailer with backhoe, this thing is plenty heavy. I mounted a vise near one end. Works great.

Morning Matt.
I agree w/the other gentlemen...thicker the better,for you never know what project maybe in store in years to come,also someday you may want to make a special jig or clamp,and thicker the table top for drilling & taping the better.

If this is just a rolling workbench a 1/4" top will suffice. If you are going to use it for jig work, welding things to the top then go 1/2 - 3/4". Not only will it flex less but you can drill & tap holes for removable fixtures.
Be careful about excessive overhang on the top. Being on castors reduces the stability& excessive overhang could make it worse. Setting something heavy on the near edge could cause it to overturn & get your feet before you could react. I'd not go over 2", just enough for a clamp to grab. Or you could extend the legs out to the dimension of the top. MikeD74T

I use a 1/2" palte top. very strong and good to clamp small work on for welding. I have about the same size table. What I did was, take the wheels off so the table is stable. I mounted 2 7" wheels on the back legs just touching the floor. When I want to move the table I lift one end, like a wheel barrow, it lifts to the wheels and I roll it around. works good and more stable when in use.

I an currently building a 4' x 6' welding table. The top is 3/8" A36 plate that I paid $140 for over a year ago. The entire frame is 2" x 2" x 1/8" square tubing. The casters I am using are 4" x 2" polyurethane molded on steel and are rated for 700 lbs each.

I am pretty much following the plans, with my own personal modifications, that are available on the Miller Welding Projects site.

I would think that 1/4" plate would be too light for any serious welding table. Thicker is always better but you have to figure in the usage and costs involved.

BTW, welding tables and welding carts are two of the most discussed projects on both the Miller Motorsports forum and the Hobart Welders forums. You should hop on over to those and see what others have successfully done.

Matt, Heavier is always better. That being said, I have a nice table with a 1/4" top that I pound on pretty hard and it still looks like new. 3/8" would look cooler, but 1'4 has worked for me.

I would think you would want some edge sticking out all around for clamping projects to, I love C clamps and vise grips

A 5" overhang with a 3/8" plate would be just fine, on 1/4" plate it might be a little weak. I am going 4" on mine with 3/8" plate. As long as the cart provides a stable platform you should have no problem.
