I agree that some brands of CA are more potent than others. There is even an odorless variety but is IT expensive!, lol...

I've tried several different ones and have found HandiBond to be the least offensive when it goes "off". It's also very affordable, a nice plus.

My Dad had to give up building as he developed a severe allergic reaction to CA's. The ease and convenience of "building in your hands" with CA spoiled him. His having to use clamps, T-pins and waiting really took it's toll. He sold out and took up karaoke :-).

I use a respirator in the Winter months when proper ventilation isn't available but this is only for close-in work.

Another point...I've found that medium and thick CA's don't "go-off" like the thin variety and if I use an activator, the cure time is almost as quick as using the thinner stuff. Hardly any fumes at all. Granted, using the activator doesn't allow as strong a bonding but I've yet to experience a failure using this method of construction.

Since you've made the switch back to white glue, thin it with water abit to allow better wood penetration for stronger bonding. I used to squirt all the glue into a container, thin it out and pour it back into the applicator bottle. The excess was stored in a glass jar, tightly sealed for future use. Just a thought.

I have a BUSA E-III, too. Mine's an original kit from the early 80's. It was sitting in my Uncle's basement until after his death. My Aunt gave it to me along with a bunch of other kits and supplies. Our family have been model builders since the 40's.

Good luck with your build. I'll be interested in seeing photos along the way.
