Im so cramped for work space It drives me crazy, if Im looking for something it's in one of three spots,so a lot of walking and digging thru bins and cabinets..Im going to move south in a few years and WILL put up a steel building to work out of and FINALLY organize my parts and shop..so for today I cut out some longer caster mounts for the pressbrake out of some 3"c-channel scrap; it was tippy as built,when you moved the brake you had to be careful not to pull too hard sideways or it would tip over..more than once I had a disaster but it survived..so wider caster wheel mounts were in order..only after cutting them did I discover two different runs of 3"c-channel with different leg heights side for side..musta been some irregular runs of channel! just another challenge..
