Not sure but 4638 will start work on this soon
rolling on this
So far the design above without skin and wheels is "Mass = 333.40 pounds" its 95% 1" square steel tube. Its 97 long and 72 high. We may make it smaller but it holds everything but the bot. The tables fold up and go in the back and all the tools and parts in the front. We will purchase an inexpensive tool chest that will be the front center opening. Then our parts organizers will slide in top right and left. Still a lot of changes and consideration to go but in the process.
