Ok, I completed the battle to put rubber hose over the 070 top handle. I started that project about half a year ago. I also put a new tip on the bar as the other one had buggered up. I then disassembled the old tip sprocket, found out what the issue was, repaired it and someday plan to put that back together along with its 50 or so little bitty bearings. Maybe I should have tried repairing that first?
Anyway, long and knuckle busting story short, the 070 is back in service and perhaps tomorrow or Saturday I will go visit a fallen tree...
