Sim Pedals 2

ever since i'd received positive feedback and interest RE my original desktop sim pedals i intended to evolve the design. though the originals were durable, reliable, ergonomic, accurate and fairly straightforward to build and set up, there was room for improvement:

  • exposed potentiometers
  • generally mechanically crude
  • base too short
  • basic materials
  • imprecise construction

    extended use exposed problems with the springs moving out of alignment or getting jammed, or not fully returning. the solder joints broke, the wires were too short, and keyboard-pedal transitions needed work.

    finally and ultimately, the potentiometers wore out. they were somewhat awkward to remove and replace, especially due to the modifications required of thier spindles. if i were going to sell these to people, and they were going to wear out, they should at least be easy and cost-effective to fix.

    this is what i came up with in blender. the mechanism is the same, but parts have been redesigned and it's all been given a bit of a shuffle. now the wooden base is more integral, the potentiometers have a bit more sweep, and less foam is required to keep the wrist flat.

    the pedal hubs are the biggest engineering change. they attach the pedal securely and precisely to the potentiometer spindles, which only need cutting to length, and the grub screw allows them to be repositioned so as to sweep new areas as the resistance track wears.

    the pedal hubs are cut-down aluminium knobs from Jaycar. they were quite fiddly to tap. the springs are rolled from an aluminium can, giving more range than a coil spring, and are of course fully replaceable. the base is myrtle wood and was difficult to get square using hand tools. the pedals are upholstered with REAL LEATHER!

    in conclusion: they work well. they are a bit smoother than the originals and offer higher resolution and the springs dont move around. i haven't put a tip-over blade on them yet and they need cork feet at the front and a bit planed off the tail of the base. also a foam brake bottom-stop.

    they were a fair bit more complex to make, what with the cutting and tapping and i marked, punched, drilled and filed with much more attention to the blueprints, which i actually printed out. a final production-suitable design would be a simplified mixture of this design, and the old one.
