Restoration of a 1957 15 ½ ‘ Lyman
Outboard
Part 2
by Jerry Valley
Well,
so much for getting this project finished in 2 years! In Part 1 of
this article I covered the purchase of the boat, the photo
documentation during the teardown process and the
replication/refinishing of the interior furnishings and windshield
frames.Next came the stripping and fairing of the hull in the spring
of 1997. This was a very tedious process and took much longer than
originally anticipated. There must have been ten layers of paint on
that hull! I didn’t keep track but I’m sure I applied at least
15 coats of the strongest stripper I could find to get the hull down
to bare plywood. I then sanded the hull, first with 80 and then with
120 grit sandpaper.
Experience with my larger Lyman had taught me that
the hull paint had a tendency to begin to crack along the grain of
the plywood after little more than a year. To stabilize the plywood
on this project I decided to use Smith’s penetrating epoxy. This
product is the consistency of water and is applied in continuous wet
coats until no longer absorbed by the wood. After allowing this to
thoroughly dry for about a week I proceeded to fair the hull using a
fairing epoxy also made by Smith’s. This product is about the
consistency of peanut butter and was applied using a putty knife
slightly wider than the hull planks. While this is a sandable
product, it is important to apply only what is needed because it
really clogs up the sandpaper quickly. I might add that
“sandable” is a relevant term when used in regard to this
product. I applied about three coats of this product and sanded with
80 and then 120 grit paper between each coat.
When the hull was adequately faired, I applied 2
coats of an epoxy primer also made by Smith’s, sanding between
coats with 150 grit. By the time this process was finished, it was
time to put the boat in storage for another winter.The spring and
summer of 98 has brought a lot of progress. First step was to take
the boat off the trailer and invert it so the bottom of the hull
could be addressed. While it was in good condition, it had many
layers of bottom paint that needed to be removed. For this I
carefully used a belt sander. Be sure to wear a mask when sanding
off anti-fouling paint. There are some nasty ingredients in there
that I can tell you from experience are very irritating to the nose
and throat. After some minor filling of dings and screw holes, I
applied two fresh coats of copper bronze anti-fouling paint.Next
step was to re-establish the waterline which had been lost during
the stripping process. Unlike some boats, mine did not have a
waterline scribed in the hull planks.
Using the pictures I had taken during the teardown
process, I was able to determine a start and finish point for the
waterline. I then adjusted the boat so that these two points were at
the same elevation fore and aft and side to side. I then used a
technique learned form Sherwood Heggen to figure out where the
waterline should be between the two known points. This technique
entails using a clear plastic tube, longer than the waterline, and
filled with a colored liquid. With the help of an assistant, a mark
is made every 6-12" along the hull whenever the top of the
liquid is at the waterline mark. The top of the water at the other
end of the tube is then also at exactly this same point and the mark
is made.Use a tube at least 3/8” inside diameter to minimize
errors caused by the meniscus of the fluid. Once this process has
been completed on both sides, merely connect the dots with masking
tape to a fair curve and you have the location of the waterline.
Simple and accurate.I next applied 3 coats of white hull paint and
applied the waterline stripe.
These are tasks made much easier when the boat is
upside down. While the hull was off the trailer, I took the
opportunity to have the trailer sandblasted, primed and painted. I
also installed new carpeting on the bunks as well as a new winch,
hitch , safety chains and lights. The hubcaps were sent out for much
needed replating. Incidentally, if you are looking for a place to
have your trailer done, I can highly recommend Brighton Sandblasting
in Blaine. They were reasonably priced, gave me one week turnaround
and are equipped to do painting as well as sandblasting.Once the
trailer restoration was completed it was time to turn the hull right
side up once again and get on with the rest of the project.With the
exterior of the hull essentially completed except for the transom,
the newly varnished spray rails and new Lyman badges were installed.
Now it was finally beginning to look like the boat I had envisioned.
I also sprayed the interior of the hull with sand colored, water
repellent stain.
Were I to do it over again, I would not use this
product as it still isn’t completely dry after four weeks. This
boat originally had plywood decks. These are being replaced with
solid mahogany planks. To accommodate installation of the planks, I
had to install battens to bridge the deck beams. This was done using
a router and a special jig to inset the battens flush with the top
of the beams. As this article goes to press I am in the process of
rough-fitting the decking. It will then be removed, properly bedded
with Sika-flex, reinstalled and all the bungs put in place.
Hopefully all this will be completed before the snow once again
flies.
Another change that I am making to the boat in the
interest of improving the overall appearance is to install ceiling
boards to the inner hull sides. These are thin boards, approximately
¼” x 3” wide that run the length of the interior from the
gunwale on down. In this case, there will be five boards per side
with 1/8” spacing between the boards. These have been fitted,
removed, stained and varnished, and are now ready to re-install.
Fitting the ceiling boards proved to be quite a challenge because of
the large amount of fore and aft and vertical curvature in the hull.
Fortunately the thin cross section of the boards makes them fairly
easy to twist and bend into shape without resorting to steaming.
The original budget I had established for this
project was $3000. While I don’t know the exact number, I do know
that I am still under my target and expect to finish the project
under budget, but it will be close. Major expenditures since the
last article have been $250 for trailer restoration and $200 for
plating. The only remaining major expense will be new glass for the
windshield and side windows which I estimate at about $250.
Let’s hope the final article for this series is
not another two years away!
Thank you, Jerry. One more boat saved!
Where have all the Lapstrakes gone? We the BSLOL’ers should
resurrect a few more of these good-looking boats. It is an
economical way to get into classic wood boats and they are are a
great riding boat. And, as usual, what do we say? Don’t Destroy
It; Restore It!
