Underwater ROV

Step 2 Frame

Here is the beginning of the frame I am building for the ROV. I cut plexiglas windows and sanded them to fit inside the pipe. This is Schedule 40 ABS pipe, commonly used for sewage. When joining this pipe, make sure you use solvent glue that is specifically made for gluing ABS. Normal PVC cement will not work or create a poor bond that could leak. I am also using a marine sealant to seal the plexiglas and prevent water from coming in. On the back end, I am using screw plugs in case i need to access the batteries or electronics again. I will need to wrap the threads in teflon tape to make it water tight.

After some testing, I found that the screw plugs leak, so I switched over to rubber end caps that have a band clamp to secure them.
