So true. The fumes are nasty. About a year a go I was blowing out some screw holes that I had hardened with thin ca. A tiny drop spattered onto the back of my throat. Very small about the size of a pin head. I have no idea how it got that far, but the quickly cured feeling was nasty and the tiny "tight spot" on my throat stayed for about 2 weeks. After that I now always hold my breath when I use any ca. Also a small fan blowing across your work area helps immensely in not having to breathe any fumes. I do this when I'm skinning. The fumes from pooled medium and thick ca are intense. I also wear safety glasses. I usually keep the glasses on so I don't forget to put them on. I also use aliphatic resin a lot as it dries fairly quick. I have a gallon of the stuff! Lately I have been using gumby glue (gorilla) a lot. I would like try the cheaper probond stuff but no stores in our area stock the cheaper stuff. but it is amazing how little gorilla glue is needed for a strong bond. When I build my King Kobra I will use the foaming probond to skin the foam cores as it bonds balsa sheeting to foam with a vengence. I will have to venture to a local larger city and get the probond.

mxaexm, your building looks very good! A strong wing partially comes from having no gaps at all on between the sheer webs, ribs and spars. It looks like you are achieving this.
