Thanks!
It's been so long I can't really remember. It probably took 25 - 30 hours, and a few hundred dollars in parts, steel, sandblasting, painting, wire, gas, and electricity. It's more economical to buy one if you don't want to build all of your own shtuff. But the way I do is it is building everything for my rig front to back top to bottom, for the most part that is. That way it fits me and my uses and you really can't put a price on that.
So if you have lots of time, and room you can put one together for less than an off the shelf.
I would do it this way again.
