Good Morning Ed:

I also experience a severe reaction to CA fumes. I switched to odorless CA several years ago. IMHO it works as well as regular CA, without the discomfort! Some will disagree, but who ever heard of differing opinions in our hobby? The added expense is a non issue, if you experience a severe reaction to regular CA. Even with the odorless stuff I try to have plenty of ventilation and use a fan.

I have a new respirator, which I have yet to test with regular CA. I sure cuts down on the balsa dust that you inhale during sanding.

I have started using a lot of "yellow carpenters glue" in place of CA. It takes a little longer, and you have to modify your building techniques, but the stuff builds light and strong. Some of the best is "Old Yeller Quickset" from Woodworkers Supply in Casper, WY.

Use caution while using regular CA. Use the fan and have plenty of ventilation. The stuff is pure poison! Anything with cyanide in it can't be good to inhale. They used to use a form of cyanide in the gas chambers.
