I have 2 Ultimarc T-Stiks (one T-Stik Plus) but the shafts are too short for 3/4" wood. They are playable and quick, but I would like more movement on them. I do not know how to route the board so that the controllers have a deeper slot. Is there a good replacement shaft that is compatible with the T-Stiks? I know there are good ones for the Happ Joysticks, but I have not yet found one for Ultimarc's sticks.
