Got the offset front sprocket made up, and the sprocket nut figured out (after a few different versions as you see). Think I'm getting my tig skills back slowly.... Added a .520" spacer between 2 sprockets and jigged them up and welded them together. Also re-hardened the sprockets after welding (black finish). Now the chain has plenty of clearance from the tire. Engine is tacked in place, and l will be welding up the top tubes/seat next and the mid engine mounts will probably be turnbuckle style tubes so they are removable for engine service, etc.
