Introduction: Supreme Mobile Welding Table
Decided to diversify my building creativity by learning to weld last year. Working with wood my whole life I was eager and curious to learn how to weld. With lots of trial and error, YouTube and stubbornness I'm starting to get the hang of it.
I got the idea for this table because I do not have a garage big enough to weld in and wanted a big flat workspace for any future projects that could be easily moved around. Also used nothing but scrap steel for the entire build (except for the table top sheet). There are better ways to build but I just used what I had. Also cost me nothing in steel.
Step 1: Find a Trailer
Acquired and old beat up tent trailer for the base of the table. Don't have any pics of the tear down but it was quite a stubborn job ripping apart all the wood floor, furniture, and appliances down to the bare frame.
Step 2: Legs
Next I welded square tubing to each corner to act as legs for the table top and also hold the leg extensions inside which slide up and down.
Drilled holes through both and used a bolt pin to hold them in place.
Later on I actually changed the design and removed the white tubing and replaced them with much taller ones after I found some more steel.
Step 3: Basic Framework
Using the odd length pieces of steel tubing I had I built the table framework next. Added another in the middle on both sides for extra support as well. And a bunch of angle braces. All out of junk tubing.
Step 4: Wheel Fenders
To protect the wheels from sparks or if I ever wanted to pull it down the road the trailer needed fenders. This barrel was the right diameter and worked perfectly. Welded some angle iron brackets to the frame, drilled holes, and secured them in place with bolts.
Step 5: Under Carriage
I wanted to have a place for storage of anything underneath so I went with just a sheet of 3/4" fir plywood. Used some hillbilly stain to weather proof it. Welded angle iron pieces along both sides to hold the plywood in place. Drilled holes into the original cross members of the trailer and used carriage bolts. And also welded angle iron pieces with holes drilled to the for corners. This way I can bolt plywood sides to them if I want to in the future.
Step 6: Table Top Sheet
Putting the 6'10' sheet of steel required a bit of improvising since I don't have any heavy equipment for lifting. Turned out ok angling both trailers down and using a come along to pull the sheet across.
Afterwards I welded the sheet directly to the frame work.
Step 7: Finish
Pretty much done. Will probably put some more accessories onto it in the future but for now I just bolted a bench vice to one corner.
Works out great dropping the support legs without the need for another lifting jack. I basically lower the A frame jack in the front all the way down to the ground first. This way the rear lifts up and I can dropped the back two legs and pin them. Then I just crank the jack up again to drop the from two.
Sturdy as a rock.
