Ah memories of cannibalizing old TV sets. If you go with a used one, make sure you get a linear taper and not an audio (logarithmic) taper pot.

OK, if I understand the potentiometer conundrum, the Curtis uses a 0 - 5K ohm variable resistor (the center and one end of a pot.), and the forklift controller came with a ~23K ohm pot. From your photos, it looks like a common part:


a single-turn, linear-taper, 1/4" shaft carbon potentiometer rated at 1 Watt (without a built-in switch I assume). Don't put an underrated part in or you might smoke pot .

Anyway, if you can't get the exact length shaft, you can always go over-size and cut it to fit (usu. aluminum).

So, which controller are you going to be using?
