With help from my friend Victor, we bent and tapped aluminum brackets and fitted new holding tank cover panel. Thumb screws will allow easy access to the Y-valve and seacocks under the sink.
Used 1″ binder attachment for my Sailrite sewing machine to create reinforced edging on grab rail covers. Added fasteners – first try at doing that with the SnapRite tool and they turned out OK.
After dry-fitting and making final adjustments, the common sense fasteners were installed using special hole punches from SailRite. Finally, the cover took its permanent place and the project is DONE!
