So I have eight bronze portlights
, each an oval of roughly 6 x 12 inches. They are chromed with varying amounts of wear, superficial corrosion
, etc. Typical in appearance for being 40 years old.
I've thought through the standard options of doing nothing, stripping, painting, polish, re-chrome, etc. Asumming that I do any work
on a portlight, I'm looking at $200 to $400 per hole.
I've Googled what I propose here but could not find it.
Doing some brainstorming I came up with idea that I'm sure is not new, but basically involves a simple captive (horizontal) slide mechanism backed up by force-applying compression
~dogs. All of this held against the inside of the hull/deck, potentially with no visible external fasteners, compression
ring. Furthermore, a drip pan would cover the mechanism and catch-direct and leak out of the hull/cabin.
All together, I reckon you could build one sliding portlight for about $25. Materials include a piece of acrylic/glass, some angle aluminum
to act as tracks above and below the opening, rubber seal, VHB tape, a sliding latch machism lateral to the window, two "bridges" (hard to describe) but sit proud to the sliding aluminum
extrusions allowing a means to fit compressive dogs) with a "drip pan" covering the entire mechanism stuck to the inside of the hull/deck vertical surface.
The sliding mechanism would obviously allow for partial opening as well as the installation
of a cheap
actuator for the sailor who must have power windows (kidding aside, such actuators could be used to shut all ports
, but that's a story for a million dollar boat).
Hard to describe, but I can upload some scratch drawings. Importantly, this design also allows one to modify the hole opening such that the external appearance about thr portlight has no (needed) visible hardware
, bright work
, etc. Low maintenance
, looks good, costs next to nothing to build or replace. If it works, to me it's a no-brainer.
This by nature takes up cabin
wall space lateral to the window, but in many designs there is space.
Before going further, has anyone seen anything like this?
