WSS, I found that metal saw horses work well. When I built my 5 x 10 table I placed the main frame sections ( 3 x 8 x 3/16 tube ) on top of 6 saw horses and then used shims to level the frame before finish welding. A 6' to 8' level can be used to help get all the frame sections leveled. Once I had the main frame level I welded on the legs with adjustable levelers in the bottom. Mind you the legs were not touching the floor as the the main frame was still being supported by the saw horses.
I purchased the levelors at Enco. I used the 3/4" stud with 3" diameter base.

Once the legs were in place I used my fork lift to raise the table one side at a time and removed the saw horses. Once the table was on the floor I used the levelers to re - level the table. You can then finish building the table.
It has been 3 years since I built my table. It is a standard style table. Dynatorch has come out with so many new features I thought it was time to upgrade. I am waiting for one last shipment from Dynatorch and the upgrade will begin. I will be adding the drop side option and if I can make it work with the existing hardware it will be a (dual drop), a new laser locator (their first ones were battery powered), the DASH system and the Dynascribe. The Dynatorch guys have been great at helping me with the up grade parts.
I will post some pictures when I get started. Here is the thread with pics of my existing table.
