Got my disk in...
the taper nose where the chain drive run on 2 of the planters
was worn really bad...as in half the tape was worn away..
so I have been putting new bushings in and repairing that taper
I actually set up the housing in my Bridgeport..milled off the old taper
bored the hole out to 1" and made a new bushing with the taper made onto it..
