I found some good sturdy locking casters on McMaster-Carrs web site and ordered them today. I got the box for the table tack welded, but I still have to square it up before I finish the welds and start the triangulation. It will be very handy to be able to move the frame around during construction. I still haven’t completely worked out how to get it off the build table when complete, but it will probably involve a saw horse and an engine hoist.
