Thrusters Part 2

Step two:  

Saw off a small piece of the pipe or coupling.   

Step three:

Using a sharpie, draw the inner diameter of your fitting on the rubber. (its hard to see, but I promise it is there.)  Then cut it out with some scissors.

Step four:

Using a Q-tip place some of the Seal All in the area around the shaft hole.  Then place your rubber circle in the cap and allow it to dry fully.

Step five:

Using a needle, place a hole in the shaft hole where the shaft will later poke through.

Step six:

Using a Q-tip, smear some Seal all on one side of the washer and place it on top of the motor as shown.  Don't use to much.  We don't want any Seal All in the motor.  Allow cement to dry.

Step seven:

Grab your tube of plumbers grease and generously smear it on top of the motor as shown. We want to fill the area between the motor and the cap so no water can penetrate the motor.

Step eight:

Using yet another Q-tip, smear the outside of the motor casing with Seal All and place the cap on.

Step nine: While this is drying, solder some wire to the leads of the motor.  I remove the outer later on Cat 5 cable and use one of the twisted pairs.  Remember,  this wire is your tether to your controls.  Think of it as an electronic leash.  The longer the cable the farther away your ROV can travel from you.  (Note: If you plan to use a USB camera on your ROV, you will be limited to approximately 20 feet since the length of a USB cable can not be much longer.)
