4 Nozzle Off Grid Micro Hydro Turbine Part 5 Motorised Spear Valve Control

This new turbine is going to be controlled remotely so i set about designing a drive system to move the spear valve. The challenge with this is it need to be able to move in and out is it drives. I used to long bolts and drilled them out and then used two smaller bolts as pins that slide along the inside of the tubes. it works very well but i might need to change the cast aluminium part in the future to get less movement.
