In this video I show how to friction spin weld tank fittings for my black waste tank on my vintage Airstream trailer I am renovating. I show some tips and techniques of using the hole saw bits and the router recommendations. This video would be helpful for anyone building a van camper, skoolie, restoring a vintage trailer or building their own DIY homemade camper.

UPDATE.... 11/28/2020. Not mentioned or shown in this video, it is important to spin weld fittings long enough for the fitting to be flush to the outside surface inside the tank otherwise it is possible for the fitting to leak in the future.
