Just had a flash... Repurpose a 4 wheel mobility skooter into an all terrain remote controlled welding cart. Got the Jazzy which has a board issue so it wouldnt be too much of a stretch to build a tube chassis for my tig and plaz to ride around the rough shop floor and outside the doors. More on this idea after I get back from dialysis. Hopefully it will be a little better formulated idea by then. Just a passing thought while I was getting ready for my hour ride to a 4 hour treatment. HMMMM, might be a fun and neat project.
