View Full Version : Welding Rig Build
01-16-2007, 02:01 AM
So in a weird sequence of events, I now have a new truck (well, new to me). My old truck broke down last week and I finally got fed up and decided to sell it. The repair was not hard but I was just getting tired of fixing stuff week after week. I ended putting an ad on craigslist and I sold my truck the next day! I never thought it would sell so fast so I didn’t really have another vehicle lined up. It just so happened that the local Chevy dealership had exactly what I wanted on the lot. After about 3 hours in the dealership I drove away with the truck. Anyways, here’s where you guy come in.
I need this truck as a daily driver but it is also going to be my welding rig. My last truck carried my Miller Trailblazer and all my tools and this truck has to do the same, only better. I have some ideas for toolboxes, O/A tank mounts, a rack, etc. but I want to hear from you guys. On my old truck I made the welder removable and this truck has to be the same. Anyone have a welding rig or any advice for a clean removable setup? Any trick ways of mounting something like this? (the welder alone weighs about 600lbs).
I think I’ll draw up my ideas and post them tomorrow but in the meantime show me what you’ve got!
Here’s the new truck. I will definitely be upgrading the stance and tires on this truck too, no worries!
And here’s the old rig. This is an old picture; I built racks and modified this truck a lot since then…

So I quickly sketched what I want to do for a toolbox and it looks something like this:
What I need help on is a good way to mount this to the bed of the truck. I want to be able to easily remove the toolbox and I want the mounts to be low profile so I can still use my truck bed when the toolbox is removed. Do you guys have any ideas of latches that would work? Do you have any ideas of simple, low-profile mounts?
Just trying to get some ideas here...

since the drawing does not show the tailgate I have to ask will you be using the gate to keep the box in?
will the bedside be higher than the box? if not couldnt you bolt some angle to the top of the bedside and maybe have a pin so you could lock it inside the box, or maybe just bolt it with carrage bolts (no head out side)
wait scratch that the box isnt gonna be as wide as the bed....
well maybe at the front and tailgate this would work, and since the tailgate would be bolted to the box you couldnt lower it with out unbolting it (cant steel your junk very easy
or you could put a receiver in the bed
like a groove at the front the box slides under (tongue on box groove in bed, bolts or lock at rear?)
you gonna trailer the welder?

Thanks for the reply. I guess I wasn't very clear on the position of the toolbox and welder. The welder will be mounted in the bed of the truck all the way forward (towards the cab). The sketch is drawn as if you were standing behind the truck looking forward. I measured things out today and it looks like I have just enough room for the welder and a 4' toolbox (shortbed truck).
Now i'm thinking, why not suspend the toolbox over the bed rails just like those diamond plate boxes everyone runs just behind the cab... Now the ideas are flowing, keep it coming...

if you did suspend it over the bed rails you would gain more storage space around the wheel wells
think of a box where the top extends horizontally to the bed rails with lids opening to access the area between the out side of the box and the inside of the bed

Well since this thread is called “Welding Rig Build” I guess I should get building…
I had the chance to work on the toolbox today and got quite a bit done. I had some materials left over from other jobs that I sort-of put together and started building.
The frame of the toolbox is 1-1/2” angle and will be skinned with 16 ga. Sheet. This thing is going to be Tough (and Heavy!). I made the top out of some 1” square tube to save some weight.
I had a piece of ¾” x 9 ga. expanded that was the exact size I wanted to make the toolbox, so I decided to use that as the underside of the box. I will make some shelves later to put small parts in so the expanded will work fine for now.
I want to make the toolbox and welder removable so I can have a full truck bed if I need it. Also, I want any part that will be “permanently” attached to the truck to not be in the way. Since I plan on building a rack for this truck later, I decided to build the rail for that and make the toolbox “hang” from it.
I attached the rail to the truck by cutting out some plate to fit inside the stake pockets and welded a nut to the backside. All I have to do is slide the plate into the stake pocket, put a bolt through the rail, and then tighten down the bolt. This just acts like a big washer to hold the rail down; no drilling into the bed of the truck.
The toolbox will hang from (and bolt to) small tabs I welded to the rails.
I actually used my friend’s small 110V Lincoln Mig welder for most of this project. He leaves it at my shop and I figured I would try it out on this project. I’m not used to a duty cycle and I tripped the thermal overload a couple times. My normal equipment is made to run practically all day (Trailblazer welder/generator and 8RC suitcase wirefeeder). I was surprised that this little machine could lay down a pretty good bead (that’s a ¼” lap weld).
I should be able to work on this a little more tomorrow. I’ll keep posting…

If you add in front and in back of your image URLs, they will show up without having to click them.

Yeah I tried that but it's still will only display it as a link. I must be doing something wrong...

Here is a stripped down link of some pics I took of mine. I can MIG and have all of the O/A tanks, lines, etc outfitted. Works excellent.

Thanks for the link jackalope, nice set-up. I thought about building a trailer for the welder for a long time. I finally decided that it wasn't the best idea for me. Out here there isn't much room to manuever a trailer around (at least at most of the jobs I do), so for now i'm going to squeeze it all into the truck.
I'm still working on a good mount for the welder; i have a couple ideas. I should be able to work on this some more today. I'll keep posting...
p.s. sorry about the picture links guys. I can't get them to work right...

Got the basic toolbox finished today. This thing is a beast! It takes up 2/3 of the bed. I will add mounts for o/a cylinders, hoses, cables, etc. Also, I still need to mount the welder. It's getting there though...
still sorry about the pic links.. oh well.

That is a beast of a box. How much do you think it weighs??
You need a couple lift cylinders for that lid. Looks very sweet.

Thanks for the replys guys. I've been on a road trip for a couple days (that's why i needed the toolbox done so quick).
Jackalope, this thing has got to weigh around 60-70 lbs. I could carry it myself without the sheet metal on it but when I put all that 16 ga. on I could barely move it around on the table (it's akward too). And yeah, I need a couple lift cylinders to hold the top open. It's a pretty basic box right now, there's lots of little things to do to it. I still haven't painted the inside.
I'll be working on this project off and on this week. Lots more to go...
