I have Gull Ash (?) oars. I damaged two of them: one split down the blade breaking off a 1" to 2" wide piece the length of the blade, the other oar cracked mid-shaft and has a wide flake that followed the grain but didn't break off or in two. The latter will require that I inject a non-viscous glue into the crack so that it can penetrate deep before I clamp it. I can't get the flake to open very wide, but could get a syringe in there if I knew what glue would be thin enough to penetrate.
What glue/expoy would be best for such repairs?
