Could have been that at the time I was building Guillows stick on frame free-flights . . . and probably using 7X more glue than necessary and using garnet sandpaper that was well and truly beyond worn out. (60's and 70's I guess, * sigh *)

I'm thinking the Fletch-tite I use to attach feathers to cedar (lacquered) arrows must be similar to Duco Cement. Familiar odor and ooze, but is very flexible and seems it would be a bear to sand - but the tip is tiny so not much is used or needed. Are "Ambroid" glues acetone & nitrate based?
