Bilge Fillet Complete-ish

Nice weekend weather gave me a window of opportunity to finish up the center seam on my canoe.  I remembered to use the tape trick this time, and the line came out nice and clean (except for the horrors of the frame fillets).  Considering that I don't intend to paint the interior, I think I can live with the result.

The reason I describe it as "complete-ish" rather than "complete" is that there's a sanding and fiberglass taping step still to do.  One smooths the top of the fillet out into a graceful curve, then epoxy and glass tape are applied to protect and strengthen the joint.  Combined with the filler and glass tape on the exterior side of the joint, the result is sort of an I-beam structure that gradually blends into the plywood.

Also, there's a bit of remedial filleting to do before we can glass over it.  Towards the bow, my mixture was a little thin and didn't fill as high as the wire stitches, as you can see in the second photo here.  The glass tape really needs to have a smooth surface to sit on, or else you get bubbles of air beneath it.  So I'll have to fill that in a little, too.

But I think I'll fillet the chines and the outsides of the joints first - that way, I can do my glassing all at once.  Hopefully, that will give me a chance to get "good at it" and produce a better result.

The weather man says that our unseasonably warm temperatures will continue for most of this week, so there should be some good opportunities for filleting in the early evenings.  More news as it happens....

<SARCASM>Oh, How I've Missed This</SARCASM>

It's been a really, really long time since I had anything to report on the boat building front.  I let a week of warm temperatures slip by without resuming the project, because I was finishing up a car project (not a Land Rover, but sort of close: a 1987 4Runner) during that time.  But the 4Runner is finally sorted & registered, and I seem to recall stating a spring 2012 launch goal for this canoe, so when the temperatures rose to epoxy-curing levels again, I knew it was time to put the excuses aside and get to work.

I lowered the hull, swept and vacuumed the dust out of it, and mixed a big batch of thick fillet epoxy to do the semi-vertical stern joint with.  Found that a cat had urinated in the boatbuilding supplies box, right on my dust mask, so I had to mix without a mask.... Had a little trouble getting the mixed epoxy into my ad-hoc applicator system (the Ziploc bag with a corner cut off).... Accidentally spilled epoxy on my table saw table.... And proceeded to make a fair mess of the work, to boot.

When the spills were cleaned up, and all the epoxy had been coaxed into its rightful place (more or less), I straightened up and surveyed the carnage.  To be fair, the stern looks better than the bow, really, and both of these places will be covered by the decks when the boat is done, so I should stop complaining.  Despite the hassle of filleting, it really is good to be back at work on this project.  As long as the weather holds, I'll be working to meet that launch goal, and I'll keep you posted.
