Hi, my name is Francis Vega and I have been working metal for over 30 years. I saw pictures of your table at Dynatorch when I pick up our new machine. Your table certainly did have a bad bow in the frame.
Whoever welded the extra angle support on to the table with a continuous 12 foot weld should get a swift kick? I am certain that this was a mod that you did because the extra angle is not shown on their plans or their website. All the heat you put into that long weld is what caused the bow. Don't blame others for what you did.
I have been using CNC plasma and water- jet machines for the past 10 years. The Dynatorch system is one of the most cost effective machines I own. It move fast and cuts super sweet. If you don't think I know what I am talking about, then check out my work at
