I have an electrovert 10" machine with a single platten preheater, I would like
to change over to VOC free flux.  I know that I need more evaporation for the
water. I figure that my options are the following:
	New machine --$$??@@!!
	Spray Fluxing - will help by reducing the flux present in the first place
	Convective preheat - need more hot dry air to remove H2O
I have probably 18" that I could add convective preheat in, which would give me
an overall preheat length of 27", which is not all that much, but combined with
convective dry air, this might be enough. 

Can anybody give me some direction on building a spray fluxer?

We are presently using Kester 951 which generally works well, but I have seen
better soldering  with the VOC free if I can make the process work, and I won't
have to accumulate the spent alcohol flux.
