u360 long shaft
Franco B:
The length of a screw driver doesn't increase the amount of torque you can apply, its the diameter of the handle. You are correct in a sense though as longer screwdrivers tend to have a larger diameter handle but its not always the case. A screw driver with a longer shaft may enable you to get in a position where you can apply more torque though.
A joystick is essentially a lever. The longer the ball/bat top as away from the elbow joint etc, the less force will be required to actuate the switches. You could counter this by using a stronger spring. An increased shaft length from the pivot to the ball/bat top will also increase the throw (length of horizontal movement required to actuate the switch). The longer the shaft, the greater the throw.

Really?? It's been about 20 years since my last college level physics class, but T = F x L, where L is length (F = force). If you are using a screwdriver to remove a screw, then perhaps the length doesn't matter. If you are using it as a lever, then the length certainly determines how much torque you can exert on an object. I would submit that the act of moving a joystick is more of a levering action.

Ah I see, I was talking about the normal use of a screw driver. I didn't think he was talking about using it as a lever. In that case Ummon was right in what he said.

I'd still be interested in these jsut to give them a try, so if you get a chance to make them just pm me and I'll send you whatever paypal amount is needed.
