Building an Aligator

[f350ca]

Cut out the parts for the paddle wheel hubs on the plasma table. Basically two 24 inch disks with spacers between to bolt the wooden spokes to. The outside disk is slotted to allow it to form a cone, to let the outer spokes splay out to the 16 inch wide paddles. The plate was really rusty, after I cut the parts out we had them sand blasted, decided to cut some 4 inch holes and half circles in the dividers after they were cleaned up. Surprisingly the cuts were rougher after sandblasting than before. Think maybe the rough pitted surface deflects the arc worse than when the pits were full of oxide.
