Filling the football

March 3, 2013 § 3 Comments

Just a quick post to show how I’m filling the football. Instead of running alternating light and dark cedar strips parallel to the centerline, this time I’m running alternating light and dark strips both along the centerline and the edge of the football to form a continuous dark line that decreases as the football grows smaller. I’ll post a picture when I’m done (it’s hard to explain), but the picture below shows the progress thus far.

Ready for some football

February 26, 2013 § Leave a comment

At long last the canoe is at the point of the build called the football. At this point it’s advisable to measure from the edges of the strips to the center of the forms to make sure that everything built up evenly. If something is off, this is the time to adjust for it. Fortunately, this build treated me well and everything was even.

Many builders choose to fill one half of the football with arcing strips, cut along the center line and then fill the other half. The method I prefer, partly because I can’t trust myself to cut a straight line, is to run a pair of strips down the center line and then fill the halves. In the past I’ve used this technique to alternate light and dark strips that run the length of the football. To people who haven’t seen me in a canoe, I call these racing stripes. This time, I’ll try something a little different. Less racing. More zen. Stay tuned.

The following picture shows the pair of strips run along the center line and the use of bungee cords to keep the strips tight against the forms.

Progress thus far

The picture below contains a couple of items that I want to touch on.

The first is the inset of the bird, done in a darker cedar than the surrounding strips. Besides being an attractive feature, the inset effectively integrates joints into an overall design. The fact that grain and color don’t match (a concern when joining strips) becomes desirable. In this way, I’ve been able to do most of the sides of the canoe without obsessing about how good the joins look.

The picture below also shows the use of 1/4″ dowels to protect the coves of the strips when clamping, and the use of both clamps and bungee cords to press the strips together. As the stripping continues, the clamps eventually become too short (or the curve of the hull makes their use impossible). At this point, I use bungees and either wind them around the assembled strips or hook them from the newly-installed strip to the base of the strongback.

The last strip

June 1, 2011 § Leave a comment

The last strip is always a bittersweet affair. There’s the endless shaping and dry-fitting until the last sliver of a strip finally slips into the tapered opening in the hull. It’s a rush when the final strip goes in, but this rush is tempered by the knowledge that what follows is an eternity of sanding (and the stink-eye from the spouse who attributes any speck of dust in the house and every sneeze of the kids and wheeze of the dog to the dust generated in the workshop… never mind that  everything — EVERYTHING — happens to be pollinating right now. It’s the dust!).

But I digress.

The picture below shows the herringbone pattern that I used to fill in the hull.

And finally the hull itself, waiting for the outer stems and, of course, the sander. And the stink-eye.

Starting the football

There comes a point when it’s no longer possible to affix strips to the internal stem. Stripping the resulting opening — the football — can be accomplished in a variety of ways. Many builders strip one half of the football, cut the excess along a straight line, and then finish the other half. It’s a nice effect when done well, but falls apart if the two halves don’t match each other perfectly.

I’ve opted for a different method for the following reasons:

  • Cutting a straight line gives me the willies
  • Matching wood between the halves is more difficult if you lack the foresight and planning required (as I do)

Instead, I’ve opted to run two strips along the centerline and then fill the halves using a herringbone pattern.

The advantages are:

  • The two strips form the straight line that I want
  • It’s easier to match grain and color by working on one half of the canoe and then the other

Running the two center strips requires some careful beveling as the hull at the ends have a pronounced angle. Towards the middle of the football beveling is less of an issue as the bottom of the canoe is relatively flat.

Here are a couple of other notes on running the center strips:

  • Clamping the strips together here is overkill. More likely than not, the pressure of the clamp will prevent the strips from lying flat against the forms. I’ve found that taping the strips together with masking tape is more than sufficient to hold them together until the glue dries.
  • It is crucial that you measure the distance between the edge of the football and the center strips at each form. Any discrepancy between the halves will be accentuated as you fill them in, particularly if you’re planning on using strips of different colors as accents.
  • Although I have opted for stapleless construction, this is one place (among a few others) where I do tack the strips to the forms. It is easy to alter the position of the strips when filling the football, so securing them is a good idea.

Here’s a picture of the football with the center strips in place:

Now for an admission of fallibility…

You’ll notice that the center strips don’t align perfectly with the strips in front in the picture above. On measuring the distance between the sides and the centerline, I noticed a small discrepancy (less than 1/8th of an inch) between the sides. Fudging the strips (as above) corrects the discrepancy. Fortunately, the external stem will cover and disguise the adjustment.

On another note: After stripping the canoe with bead and cove strips to more easily navigate the curve of the bilge, I’ve transitioned back to square edged strips. I’ve found that using bead and cove strips when filling the football tends to damage the cove, particularly if you’re fiddling around with adjustments and dry-fitting the strip multiple times. Running a rolling bevel for this part of the build is less aggravating (for me, at least).

Adding an accent strip

Funny how posts on “stripping” garner the highest number of blog visits…

At any rate, I’m just about done the accent strip, which consists of alternating light and dark western red cedar sandwiched between two strips of douglas fir.

I’ll soon transition to bead and cove strips to more easily strip the curve of the bilge.

Another canoe build

There’s something appealing about stripping — watching with growing excitement as an elegant form is revealed, lovingly shaping lengths of wood. The thumping music (I like to whistle while I work). The glue. The splinters. The sawdust.

It didn’t take me long after hanging the last canoe from the rafters (pending better paddling weather) to start daydreaming of the next canoe and how I would build it. I scoured the internet for canoe pictures — cedar strip porn. Ideas abounded.

I set up the forms on the strongback and positioned the first three strips. I was following a pattern that I’d used for the previous canoe. It was then that I decided to make things more complicated (as though building a simple canoe isn’t complicated enough). I decided to add an accent line that would follow the waterline.

It’s a great idea in theory — follow the waterline. Of course, that only applies when the boat is empty or populated on either end by individuals of the same weight. It won’t follow the waterline if I’m in it. I know what you’re asking yourself: “Is Greybeard fat?” Um… I may be an overachiever in the weight department, geared to marshaling my resources for the harsh winter that never comes. Though I’m okay with this, I didn’t think, before putting down the accent strip — all parallel to the waterline and all — that this strip would indicate just how well I had marshaled my resources over the years. In the teeter-totter that is the canoe, I’m forever on the earthbound side.

I hope that I’m wearing my PFD if this isn’t the case.

That being said, the accent strip was glued in and it was too late to change it. In the picture below, you see the accent strip (the first two strips on the top) and the three strips below that, until a few feet shy of the ends, follow the shear line. That leaves me four long triangles to fill in on either side and on the bow and stern.

I cursed myself and my dumb idea when placing the first strips to fill in the triangles (third strip from top in the picture above). The process was finicky and required several (dozen) trips between the sander and the canoe to dry-fit the pieces. After a while, and not because I started to care less, the shaping became easier and less time consuming.

In terms of how I managed to shape the strips, I used my trusty belt sander and have so far avoided an inadvertent, self-inflicted manicure.

For those of you who are interested in this kind of thing, I’m not using bead and cove strips for the sides of the boat. I’ll transition to bead and cove as I approach the bilge and then transition back to non-bead and cove for the bottom. At this point in the stripping process, the strips mount flush to one another without any work on my part. A rolling bevel may be necessary later, but for now the strips are going in as-is.

Although I prefer stapleless construction (as suggested by the unsightly blobs of hot melt glue in the first picture), I did staple the bottom-most strip and the accent strip. I stapled the latter because it was susceptible to moving as I filled in the triangular sections.
