Figured out a way to offset the butt joints. I cut a 4 x 8 panel in half lengthwise, then cut one of those in half. I spliced the entire panel together with a slight offset to account for the curve of the piece I was cutting out. In the Iroquois plans, the middle panel will work this way. This is what it looked like before I cut out the middle panels. (for some reason, I can't get the picture turned the right way, even though on photobucket it is...)
Then I went ahead and stitched in the frames. I'll finish drilling and stitching soon...
That last pic shows how the joints are now offset on the canoe...
Tried to do an end pour--twice. First time the epoxy/wood flour mix broke through the dam(n) and flooded the floor of the canoe. So I cleaned that up and made a thicker mix--much harder to get in place. Once that hardened though, I replaced the dam--added much more tape and tried to add to the end pour. Wasn't quite as thick, still pour-able, and same thing--the dam(n) gave way.
Soooo, I took the whole thing outside and propped it up in the sun
This helped slow the flow enough to stay behind the tape, and it sped up the curing of the epoxy in the sun--(and it was not a windy day or I wouldn't have propped it this way...)
And I'm no longer sure that I'll be doing an end pour on the other end...
So, onto a "dumb" question. If you cartop on a rack of some sort, do you really need the extra substance on the end, or is most of the tiedown happening in the middle at the rack???
How necessary is the other end pour? Any other techniques, tips, or tricks to try?
