on forced air hoods:

Bought units are relatively expensive - e.g. =A3300 up.
I made one using air sucked from outside with modified vacuum cleaner.
3/4 hp is overkill unless you have small bore and long piping.
Made a hood from a plastic bucket. Got some funny looks from the staff in the
DIY shop as I tried the various sizes on ! You need a plastic window and
shoulder cut-outs and armpit straps. It ended up a bit cumbersome to use.
