Hello; looking for some advice.
I am working on a 1945 18' OT Guide. About a 3-4 weeks after gluing up a 10" scarf joint on the inwale, I noticed it was beginning to fail. See attached picture. About 3" of the 10" joint is separating.
My next step is to canvas the canoe. I really don't want to go backwards, pulling the inwale off or doing any disruptive fix.While I am looking for advice on how to save this particular glued joint, I will pass along what I originally did in the glue up process:
-10" scarf, clean and dry prior to glue up.
-used System 3 T-88 Structural epoxy. From prior posts, I have learned to use structural epoxy.
-roughed up glue surface lightly with rasp
-clamped, but not so hard as to squeeze out epoxy (for 24 hours)
- mixed epoxy per instructions.
- You will note that, unfortunately, the thwart screw hole comes pretty close to, but does not touch the joint.
-all other scarfs I did at same time look good.
What I would like to do is salvage this joint, repairing it without taking the inwale off. I am looking for advice on how I can repair this partially failed joint. There will be a brass screw coming from the outwale into the rib and inwale at this location, which should help. How can I get to the failed portion and clean out 2-3" of this joint (while it is in place), re-glue and clamp?
Any thoughts would be appreciated!
Thanks!
