Does anyone know where I can buy a track wear gauge for a D47U? Has anyone reproduced them? If not does anyone have one that they would lend out so I can 3-d model it and have it laser cut? Or if there is any machinists/engineers out there can you get me a drawing for it so I can have it made? Seems like a with micrometer and a set of radius gauges I could quite easily have this thing made.
