Grumpy
Don't worry I used about a can of inox on it....
Made up a plate of some 1/2" Aluminium plate(all i had)the length of the plate was only 140mm and holes at 70mm centres, so Aluminium worked well. drilled 2 matching holes , 2 long threaded bolts and hey presto the wheel pulled straight off...well not straight off...Magic.....Those sneaky Greenfield guys would have 1 made up in the back of the shed hidden from backyard warriors like myself..ha.ha.
All is well, thanks for the help.
Just need to retension my drive chain fix the blade rotor and get back into it....Oh and maybe a paint job.
Cheers.
