Servo Mount - Automatic Blast Gate 4"/100mm

In order to automate my dust extraction system, I designed automated blast gates based on standard metal blast gates and R/C servos.

The servo mount attaches to the existing screw holes of the frame. Simply replace the existing screws by longer M4 20mm ones. The carriage mount is fixed to the lip of the carriage by a friction fit. The small arm is fixed to the grooved servo shaft via form and friction fit, as it is slightly undersized and the grooves of the metal shaft press into the plastic. As my servo shaft has an internal thread, I additonally secured the small arm via the small screw, which is normally used to mount the crossed horn onto the shaft. In terms of the servo, I used a standard sized version (no mini or micro!), as it provides sufficient torque to move the carriage. Check via the picture above, if your servo fits into the cutout. I provided two versions of the servo mount, so you can choose on which side of the blast gate you would like to mount it.
