I learned a long time ago that if you can put a thing on wheels, you should put the thing on wheels. I learned this at the History Theatre in Saint Paul, MN. Building in that shop was like building in a bowling lane. With a very low ceiling. Space was at a premium. Putting tables, saws, racks, cases, coworkers, and snacks (ok, snacks were technically on a table) on quality casters meant I could usually squish out enough room to build the thing.
For 'Three Elements,' I need to bend a bunch of 20' long tube steel to a 5' diameter. To bend said steel, I need to run it through a roller. Back and forth. Over and over. With the width of the roller, that means I need 42' of travel space. I've got about 25' useable linear feet in my shop. Aw snap! Better put the whole enchilada on some wheels. The roller is on wheels. The steel is on wheels. And if I sit on my shop skateboard (not to be confused with the 'good' skateboard), I'm on wheels. It's really kind of a fun way to spend the day.
Ok, so that last entry about taking every opportunity to wail (safely) on my musculoskeletal system? Yeah, I could motorize my tubing roller, but where's the fun in that? This baby's hand powered all the way. Gonna be a great lat and arm workout! Cue beast mode.
