RE: CA vapors
There have been a number of threads about sensitivity to CA. I am one who developed sensitivity after years of use without problems; one whiff and I spend a week or more fighting asthmatic bronchitis. A fan helps, but the slightest whiff (like getting close to check a glue joint, for example) is enough to set me off. Also, sanding a CA joint enough releases enough CA-laden dust to do the same. Have gone to alaphatics and/or odorless CA. The odorless CA has slower setup time, shorter shelf life, and is twice the price, but is a lot faster than the aliphatics. I have tried a number of brands and have found that the Bob Smith stuff is pretty good.
