Best method for mounting teflon servo arms to a base (metal or wood)? Answered
I am currently working on a simple tilt system for a mobius camera on a quadcopter. Basicly, when FPV flying, I want to be able to look directly down, and straight ahead, so I know what is below me as well as get some good footage.
I have 3 parts that need to be mounted together. A small, sub-micro servo, a plastic shell/case for the mobius camera, and a fabricated piece that extends from the bottom of the quadcopter, to the servo, allowing just enough room for the servo to turn the camera ~90 degrees.
I have hot glued the camera case/shell directly to the servo, so that the arm of it is free to turn directly above the center hole. The arm that mounts there then somehow needs to be mounted to a little board or something that extends down from below the quadcopter body. That piece is not difficult to mount, however, the teflon servo arm needs to firmly mount to that piece. So far I have tried hot glue (peels right off the teflon after some vibration) and universal JP weld (that grey and black stuff that takes a REALLY long time to set, and same problem).
Whenever possible, I prefer to not use glue, as it is messy, sloppy and bad-looking, as well as permanent and fragile when it does work. I may sometime plan to change the design, I would prefer better mounting techniques, and do not want the bonds to break with large shock from a crash landing.
