This is a project from the spring of 2006


Eolian has two hatches, fore and aft. They were constructed by building a teak frame, covering it with a piece of 1/2"
plexiglass, and then teak slats were applied to the
plexiglass - for decoration and to protect it, I assume.
Well, they are shot. The
plexiglass is crazed, the old
Cetol finish is done, the interior, which was never finished, is solid mildew, and the fittings were corroded green.

So I disassembled them into their component pieces (2 sheets of
Plexiglas, a pile of slats, and the 8 pieces of teak that made up the frames). I anticipated that it would be difficult to disassemble the frames, but all the joints were extremely loose - it appears that it was the
Plexiglas screwed on top of the frames that was holding everything together. As it turns out, the frames were assembled by simply driving a screw down
thru the half-lap corners. Poor technique. Really poor.
I stripped and sanded all the pieces, and then reassembled the frames, this time by drilling out a 1/4" hole at each corner and
doweling them with epoxy and birch dowels. Much more solid!

We bought two fresh pieces of
Plexiglas, and I ran a router around the edge. First with a flush-trim bit to make the
Plexiglas fit the frames exactly, and then with a 1/2"
round-over bit to make a finished edge. Then a trip across the buffing wheel made the routed edges transparent again. And drilling about a million holes in the
Plexiglas for the attachment of the slats, the frames, and for the two pieces of hardware that get directly attached
to the
Plexiglas:

A latch device, and a hold-open. The latch was bronze, and typically very corroded - it buffed out on the buffing wheel beautifully.
In the original hatches, the hardware was attached to the
Plexiglas like this:
- Drill holes in the Plexiglas. Make them too big for the screws.
- To prevent leaks, smear the bottom of the hardware with silicone
- Using wood screws that were too small to grip the edges of the holes, attach (??) the hardware
In fact, it was the silicone which mounted the hardware. The screws were completely useless. This time, after drilling 1/8" holes, I tapped them to 8-32 and used 8-32 machine screws to hold the hardware on. Oh yeah, and I used silicone too - the seal is necessary, and who knows - it worked as almost the only attachment for 27 years...

With 6 coats of varnish on everything and the slats on and mounted they look nothing like the old ones - they look great!

Since the hatches look so nice, Jane made some covers for them so that (hopefully) we won't have to varnish them every year. The covers have windows in them to let in the light, and the hatches can be opened without removing the covers.

A very nice job, and a great addition!

I will definitely need to be doing this on Windsong, thanks for this write-up!
As always I love reading about your projects...
Thanks!
There always seem to be plenty of projects...
Here it is at the end of the 2012 sailing season, and I am happy to report that the varnish on the hatches is holding up perfectly - the covers are wonderful!
