had a bit of spare time tonight so,
all wheels fitted with bearings, made a bit of a stuff up and predrilled wheels and body and used 8mm bolts to hold it all together, the bearings im useing are 5mm centers, problem sloved by tigging some pannel washers to body.
also cheated a little and fitted teflon runners for tracks , and added a cutting edge to the blade.
Im going to redo the ripper set up as I think it looks rubbish.
got a fear bit of clean up to do with the dremmel and a bit of sanding but its getting there.
any way picts of tonights efforts.
