More progress on the suspension......
Drive sprockets, mud breakers and swing arm buffers.
The designed swing arm buffers weren't anything like the original so I scratch built them by rolling up a solid cylinder of 80 gsm 4mm high and 3mm diameter, cut out a section to fit the base plate in.
The sprockets have Drafmodel lasercut nut shapes. As designed the outer plate on the sprocket assembly was just a flat disk - the original has a dished plate. I formed this by soaking the part in Meths (denatured alcohol for US readers) then worked the shape on a measuring spoon with the ball from an old mouse. It's important to stabilise the printed surface with Krylon spray otherwise the inkjet ink will be attacked by the alcohol.

Charlie
