Material FYI: "Brass" is Copper and Zinc. "Bronze"
is Copper and Tin. The alloy we are using is ASTM B62/B584 (formerly known
as B145-4A), or simply named "85-5-5-5" alloy (copper=85%, zinc=5%, tin=5%
& lead=5%). So, what we are using is somewhat of a hybrid between the two.
It has the strength of bronze (because of the tin), but the workability of
brass (because of the inclusion of zinc and lead). This hybrid is commonly
referred to as all of the following: "naval bronze", "naval brass",
"composition bronze" and "red brass". |

Note A: These
portholes can accommodate a
wall thickness
up to and including the stated cabin wall thickness above,
while being properly sealed for water-tightness.
For Thinner Walls,
there is no minimum thickness requirement (on thinner
walls, the spigot (flange) will protrude through the
finishing ring on the outside of the porthole assembly -
this is purely aesthetic and can be left as is or trimmed
off). For Thicker
Walls, as for
commercial or residential building or door use (non-boat
use), the portholes can be installed in thicker
walls/doors, however the inside and outside portions of
the portholes will not meet. This can be dealt with in
several ways (i.e. you can seal the edges with caulking or
you can have a craftsman make a transitional spigot
(flange) to make the 2 sides meet). This is up to you,
based on aesthetics and waterproofing requirements
associated with your application. |
