RSM 3 Tyre Truer Reciprocator

thingiverse

This is another remix but this one is for the RSM3 Slot car tyre truer. This remix uses Slot car round magnets we normally stick together and never use, the 8mm diameter ones push into the 'magnet joint' and 'magnet short arm', this is a magnetic hitch. Print two 'magnet joint' parts and glue one at each end of the slider plate so you can turn the plate round and use a fresh section of sanding paper. The RSM 3 truer should be a snug fit into the 'RSM base unit' and can be secure in place with two 'slider eccentric rollers'. These have a triple purpose, one is to hold the RSM base down, the second is to stop the slider plate lifting and thirdly as it is the eccentric can be rotated round to reduce sideways slop in the slider plate. The 'gantry' is a snug fit over the 'RSM base unit', again two 'roller' discs can be held down with screws but again may not be necessary if the fit is snug enough. The 'motor arm' slides onto the shaft of the reciprocator motor. The motor I used is a 'Geared Micro Motor Speed Reduction Gearbox - 12V ⋅ 30 RPM' I soldered wires from the reciprocator motor to the truer motor and run it at 4v
