I think for even one 1/2" bolt to "let go" of it's head you would need SIGNIFICANT pressure - like exponentially more than your warped top could ever produce.
It had a slight U to it when I got it from the laser cutter - really minor like just over 1/16" over 52". I bolted one side down first then the other and shimmed to center until it was how you see it. It did not require much to get it really good.
I messed around with the top a little and it is now nice and flat.
Next up is cutting into the side for the welder. I found a middle tool box at HD that I might buy and recess into the box as well.
Yes...after feeling the weight wanting to tip the box over when the lid is all the way up I do not think a working lid is going to be practical.
Got the top bolted on so it is now usable. I will cut the side open for the welder but I think I will also allow for a hinged door for access to storage.
Picked up the 3/8" thick laser cut top for the welding station project. Turned out quite nice - only some minor tweaking will be required to get it dead flat.
These job boxes were a special buy at HD recently and I thought it would be just right to re-purpose into a welding cart/station. This is a bit of an experiment but it should be a pretty budget friendly build.
I added a set of heavy duty castors I had on hand.
So the plan is to cut open...
Not really a custom clamp but a different use of standard clamps? I built a basic welding table and cut holes into the top of the 5/16" plate so I could use drill press clamps for lighter duty welding projects - easy and pretty cheap compared to a proper fixture table.
...and the best mod of...
I've been working on getting a system down for indexing and cutting square/rectangular tubing up to 4" tall on the table. So far 2" x 2" cuts not problem...and hopefully will be trying some 4" x 4" tonight.
Will be great for making illuminated steel gate posts with custom reliefs.
I'll try to look up it's specs but at first glance I would say no...at least not without some opening and editing of the machine. From what I can tell it has a pilot arc type of of torch firing method which is good but I think it is probably best used as a hand cutting tool only.
One other...
As far as the cut quality goes it is a great machine for thinner material...but it does not have any connectivity provision for use on a CNC. I suspect some people have devised work-arounds but even Jim Colt from Hypertherm does not recommend it. Same goes for the TD Cutmaster 42..
In order for...
