The plywood patterns were cut out slightly fat so that they each could be
sanded to the exact dimensions of the chalk board pattern, using a hand belt
sander. Note the chalk board
pattern is clamped tightly to the plywood station to make certain there is
no movement. As I have said, the stations MUST be exact. No room for error here.
Stations all done. AGAIN. . . note all the centerlines. There are two
of each pattern except for station 5 which is center. i.e., 1&9 are
alike, 2&8 are alike, 3&7 are alike and so on. You
should also put the name of the canoe and the station number on each pattern and
station to
eliminate confusion later should you build something else. Remember, a year or
two down the road you may not remember.
First begin installing the stations using C clamps only, making certain the centerlines
match perfectly. Note the tight string for aligning. When station is in perfect
alignment I installed three 1 1/4" X 1/4" lag bolts into the 2X4 cross piece to install
each station. Not wise to use nails. Lag bolts make it easy to remove later when
hull is finished and a much cleaner job. When all stations are installed, before
adding any strips you must cover their edges well with masking tape. I used two
and some had three layers. Worked fine. This tape it to keep the glue from
coming through and causing your strips to stick to the stations. I used some
duct tape on the sides of my bow and stern stems and discovered later it was a mistake. Had a
problem removing stems from the hull when turned over. Best to only use masking
tape.
Before anything else, you need to make sure all of your strips
are exactly the same in thickness AND in width. I found this
out the hard way. I had to make more strips later and it caused me
problems so had to throw some out. NEVER AGAIN. As
my shop building was taking form, I got
lucky and saw an ad in the paper that a local professional woodworking shop was
closing. I was able to purchase this sweet Rockwell-Delta 6X12 and his 2HP Grisly shop vacuum
system at a reasonable price. Though I had to completely overhaul and restore
the plane
first, it sure came in handy when I began making my strips. In the future I will make ALL strips at the
same time with extras. NEVER again as I go.
FYI - Delta and several other companies now are selling 6X12 portable planes in
the neighborhood of 350.00 Not as stable as this old gal but satisfactory for
your purposes. This one weighs right at 600 lbs.
Obviously there are several ways of cutting strips. Some use a table
saw and some use a band saw thinking they are saving money by not wasting
material the width of a saw blade. Frankly, the band saw way is OK but in my
opinion, way too time consuming unless you have a humongous
saw, large blade and lots of power. Though I have a good band saw, (not
powerful enough to cut strips fast and the table is way too small) my time was more important than a few
dollars saving. Here I'm making my strips after running the board through the
plane. I admit however, working on this small Craftsman 10 inch saw with
a small table was a hassle. (Even with lots of adjustable roller supports, of which I
have six) So about a third of the way through my strips
I purchased Craftsman's large professional table saw with all the bells and whistles.
What a difference it made. Sooooo much nicer and much quieter.
Larger table and thinner kerf blade made a big difference. Only major problem I
had, (and still do) is that I have no room in my shop for it so have to keep it
outside, well covered and with a good protective coat of WD and inspected
for rust several times a week. Now that the stripper is done, my priority
is to get my shop equipment back inside.
8'
Red Cedar on left, 10'Aromatic Cedar on right. Didn't make enough
of either so had
to make more. That's where I got into trouble. Make more than you need, all
at the same time.
Before beginning scarfing,
(A woodworking joint allowing you to make one
long cedar strip out of shorter pieces)
the strips should be bead and coved.
However, this is not set in concrete. My guess is you could do it either way.
However, which ever way you chose, bead and coving your strips is a very time consuming chore but must be done. Some builders use a separate
bit for each, some use what is called a double stacker. After researching ,
reading reports from other builders on both I decided I would try the double. It
took some trial and error testing and some time getting used to it but I finally got it down pat. The good part
about the double is that once you set it, you don't have to make any changes in
router position. It remains locked in the same position for both the bead
and the cove routing. The bead is done with bare table, with no
spacers. The cove is accomplished by adding or removing wood
strips to the router table. In my initial testing to get the exact height needed, I added strips of
computer paper under the bottom wooden slat then drilled and tapped my router
table (it's heavy aluminum) and added four screws to hold that board and spacers tightly in place. See next photo.
Note there is also another wooden slat on top of the one screwed down and
another outside which also keeps the inner board tight. There are also two short pieces across both of these
which are tightly clamped to further eliminate all movement, with some great deep adjustable clamps I found (of all
places) from Big Lots - a local discount store that sells cheap merchandise. I
later looked for these clamps in other stores but they were the only ones who
carried them. So with my setup
. . . (without the wooden slats) I made the bead
and by adding the wood (and paper shims) I could make the cove. Which type
bit you use is merely a matter of choice. There really is no easy way of doing
this task. (My opinion) However, once again, if I ever build
another stripper, all strips will be done at the same time so all will be exactly
alike.

joint sanding jig.
Random setting. Suspect it is somewhere around 30 to 35 degrees. Never bothered
to check it. Not that important. I began using it after
all strips were bead and coved.
Unless you are using full length boards which are far less time
and trouble, you have to scarf the strips to get the final length you need. I
had to use shorter boards and scarf since I couldn't find decent quality
long cedar boards locally. This was the first scarf joining
jig I made. I would not use this type again. After making most of my
strips on this jig and later discovering I had trouble with many of them not being
exactly the same width, I cut and re-scarfed what I could and threw out those I could
not, using them to make more cove protectors etc. I discontinued using this
jig and
built another which worked far better and had far less problems.
Photos of
later jig.
Use a very straight backing board, and also using a straight edge to make sure, tightly
nailed to plywood base, the two scarfs are joined with Tight Bond II glue, wax
paper is placed under and over the strip to keep from sticking, thin spacer
placed on top of the scarf joint and two wedges are placed as shown to keep the
two strips perfectly tight to the backing board. The preset
clamp puts pressure on the joint until it is dry, using care not to put too much
pressure causing the joints to slip. When I was making a lot of joints in the
beginning, I had this board set up to do three joints at a time. Clamps are wood clamps ('break
over' type) and are available from woodworking supply houses. What
makes it easy is once you set the clamp for the amount of pressure you want,
lock it and it remains at that setting for all joints. (More stuff found in my
junk bin)
OOPS! I missed taking the photo of the first strip alone. This is the second.
(And OOPS again, I forgot to mention that my paddling friend from Michigan,
Al Dasen, came over to give me some pointers on how to start the first strip.
Sorry about that Al ) The positioning of
the first strip is critical. It must be exactly the same on both sides. And
should be perfectly flush with the bottom edge of each station. The first strip
is somewhat more difficult so you begin in the center and work to the bow, then
work to the stern. (or vise-versa) To hold this strip in place properly, first you drill
the strip at each station (as you go) with a #30 drill (or 1/8th, this
eliminates the possibility of getting a split strip) and screw the strip tight
to the station with a small #6 (or close) drywall screw, (I used
1") I would not use anything less than 3/4" Remember, you DO
NOT want any problems with this first strip. If this one is off, so will every one of
your strips be on that side.
Also,
I didn't want ugly staple holes showing so I elected to use multiple squeeze
clamps and "L" brackets. The "L" brackets here are twice the size needed.
Later I thinned them down and they worked just as well. (Suggestion from Joe)
Also note here that my stem station was located wrong. (I decided I wanted stems
both for
added strength as well as looks so I had to wing it here. Gil does not use stems in his book)
The stem station
should have been at least 3/4" lower than station #1
(and 9). By the time I discovered
this it was way too late to change so I had to do a lot of extra work to solve the
problem. (Joe's help and advice here was invaluable) Also, later you will see I
converted to a bungee cord and squeeze clamp combo.
Observation: If I build another I probably will
use staples. It is 10 times faster. With staples (according to Joe) you
can lay 8 to 10 strips a day. With my procedure I could only lay one on
each side a day, and let them dry over night.
The "L" bracket is indispensable. As stated earlier, as
shown here it's
way too large. Both legs can be less than half this size. It's used to
make sure the upper strip is held tight to the lower strip using a wedge (Item
#1) that has a bead on it corresponding to the cove of the upper strip, and
lightly driven between the "L" bracket and the strip you are
installing. Then by
positioning the other L bracket leg close to the outside of all strips, (Item #2) another
wedge is driven between the vertical leg of the "L" and the outside of the upper strip keeping the upper
strip tight to the station. This is a must if you are to keep the shape of the
canoe perfect.
As my strips got taller, my squeeze clamps got too short I purchased longer ones only to
discover a short time later the amount of tumble home created a problem with clamping and I soon
ran out of clamp. Also, when I went to the longer clamps I
discovered the
pressure caused damage to the upper strip coves since they
are extremely thin and fragile. I solved that problem by making and
placing "cove protectors"
under each clamp . Below photo shows how they were made.
I needed something to protect the top strip cove
from damage. By this time I had plenty of scrap pieces of strips
laying around. Using a small 3" wood vise, I glued together a half dozen test
pieces . . . . . the center piece (with bead) to fit inside the cove of the strip
and two deeper pieces which fit over the outside edges and would hold the protector solidly in place on the strip
also keeping pressure off the thin cove edges. It worked so well so I made more and continued using them throughout the laying of strips.
"L" brackets get tightly clamped to the stations with large "C" clamps.
Also note the use of the bungees in both photos. I soon discovered I could use
bungees faster and easier for strip clamping. I slipped a 2" - 1/8th rubber
(auto) vacuum hose over the hook on one end to protect the bottom strip it hooked
onto and closed the other hook to keep it from tangling with everything. I warn
you however, if you use these, when you release the bungees clamp, you must be
very careful not to let go of the bungee before
removing the protector.
Note:
Should you decide to use the bungee method, purchase all bungees
36" or longer, 42 better.
I began with short ones and as work progressed I had to buy longer, and longer,
and longer. Getting all long ones will not only be time consuming, but cheaper
in the long run.
Since I used 2 - 3/16 X 3/4" ash strips for each inner stems I
decided to steam them before clamping because of the extra thickness so I built
a steamer using a hotplate I had purchased new, still in unopened box,
from a local flea market, several weeks before beginning the shop project in case I
needed a steamer later. The tea pot also later came from the same flea market.
The flexible tubing I purchased from a local Home Depot. It worked well.
After steaming, the strips were clamped in place overnight
then temporarily nailed to the bow stem template.
Showing the bow stem, strips temporarily nailed in place and the accent
strips. FYI -- The 3/4" white accent strips are white pine, the outer 3/4" dark
and the center 5/16" accent strips are Peruvian Walnut.
Hull almost complete. The outer stems not yet installed. Brownish 4 strips
above and below the accent strip are red cedar. The more reddish strips above
them are aromatic cedar, (same cedar as cedar chests are made of) and the light
color is white cedar
