Thanks
Are you looking for a solution to make the joysticks less sensitive, so if you let go of them they don't wobble back and forth? If you are looking to stiffen up your joysticks, just do what Team 228 has done for the past few years. Unbolt the handles from your joysticks, and you'll see instantly how the large weight of the handle affects the joystick.

To solve this problem, Team 228 machines custom [ambidextrous] handles for our joysticks using HDPE rod and/or PVC pipe. If you'd like to use some of the custom buttons on the joysticks, again this is not a problem because we also have added buttons to them as well. In the end, our lighter joystick handles on the Kit Of Parts joysticks provide for much better driver controls.

Here's some CAD drawings I made in 2006 that use a piece of PVC pipe and two custom machined HDPE plugs to make light-weight custom joystick handles:




And here's the finished product (except for the three grooves which had been forgotten to be machined into the PVC):




And here's a picture of very similar handles we used on our 2005 Operator Interface. The only difference was that these handles were one solid HDPE rod that was hollowed out for the button. They were slightly heavier and harder to install the buttons inside them, but they worked equally the same.
