Waterproofing servos

How about settling both pieces in a pan of mineral oil vacuuming then slide pieces together under oil surface.

Spent a good part of the day screwing around with trying to make some $2 servos waterproof.



This sorry subject has been sealed at the seams with rtv and has holes drilled into each cavity to allow air and liquid to pass between. It’s been filled with mineral oil but I can’t seam to get every last air bubble out after hours of work. Been fiddling with it for hours. Have subjected it to a vacuum chamber to get rid of the last few air bubbles but with no significant luck.

There has got to be a better way. Trying to avoid stepping up to the large sized bodied micro servos.
