Lexan ,, for ports .. where to purchase and get cut
 

Thinking of replacing the lexan/port on the boat. I'm thinking that
purchasing this stuff and getting it cut is the trick.

Where does one go to find Lexan? Window places? Who carries it? And do
they normally cut it for you?

It cuts fine with a saw (I've used circular saws, jigsaws, sabresaws,
handsaws) -- cut it too fast and it melts; cut it just fast enough and it
softens ever-so-slightly without clogging up the saw teeth. I suppose you
might also be able to score and break it, but I've never tried. Plastics
shops have it for certain, some hardware stores. Even places like Home Depot
may have it. For a boat, you want the "MarGard" variety. UV and scratch
resistant.

I believe the difficult/tricky part is making sure it's sealed
properly. The stuff can really flex, so the seal needs to be done
correctly.

I just called up Champion Glass, on of the local auto glass places. The did
some research and came up with the MR 10 Lexan which has a UV and scratch
resistant layer. It came cut to my specifications for half the price the
skylight company wanted for plain Acrylic.

The only hitch was that the supplier who cut it for them didn't have the
jigs on hand for the 1 3/8 in corner radius I wanted. Rather than pay extra
and wait for them to get the right jigs, I just had them sent with 1 1/4
inch radius and will sand or grind to the right radius myself.

The data sheet that came with the pieces sounds great. Scratch resistance
much closer to glass than acrylic, guaranteed against yellowing for 10 years
in building applications which should translate into a lot for a boat that
is covered 3/4 of the year. About 10 times the strength of Acrylic.

The only thing I've heard negative against this stuff is that the scratch
resistant layer may separate if the stuff is bent. Shouldn't be a problem
for skylights but I will continue to scream at people who start to step on
them. I wouldn't try it for wrap around windows on cabin sides until I knew
more about this issue.

Hi:

Did that project two years ago: six 7"x15" through bolted "deadlights"
3/8" polycarbonate = Lexan. Do shop around. I found prices vary
wildly. THe cheepest place I found was a small glass shop that also
had a contract with the local correctional insitution. Bad guyes =
Lexan. The price diffrence was somthing on the order of $2.50 compared
to $14.00 a square foot. Duhhh. I love Lexan. It takes a curve well
without cracking like acrylic, easy to cut/drill, cheep if you find
the right place. It even stops bullets! But need to use a silicon
based adhesive/selant. There is some stuff called "structural"
silicone that is totally HD. Dow Corning and others make it. Hve fun,
I did!

Look in your phone book under acrylic supplies. The people who sell it
usually can/do cut it.

I replace my companionway hatchboard with Lexan that I bought on eBay. Did
the cutting and machining myself. It was easy to work with. This is who I
bought it from:

Home Depo carries Lexan of various thicknesses and tints. There is
a learning curve to cutting it. Be sure to buy extra. Also, a bevel
looks professional. It is cheaper to practice on wood.

If you use tinted material be sure to install it on a cool cloudy
day. Heat will expand the tinted material more than your glass boat
and may result in cracks.

Drill the screw holes a bit over size and that stops cracks from
starting at the holes.

And a perfectionist weill naturally polish the holes to a mirror
smoothness.
