Bioload 75 - Reef Aquarium

[bioload]

The cleanout was simple cut on the miter saw leaving only the tread portion. I could have made the cut thinner but would like to keep all my fingers.



Once that was done I followed the same process as I did for the plug using the router. Before I could do that though I needed to get rid of those little "bumps" on the side. If I didn't I would not be able to rotate the piece on edge. I adjusted the fence to the right distance, and rotated across the bit.



and here is the completed flange/union....which is it by the way?
