Hi Ron-Glenn-Bruce-irnsrgn,
Thanks for your replies and advice Guys .There seems to be a number of improvements I need to make,not least of all to reduce air volume and blower inlet pipe diameters. The chimney size increase in diameter will increase the updraft I guess- good call. Thanks for the photos and illustrations really good and gives me an idea on whats probably gona need some mods. I had not thought about an arrestor in the chimney will do some more research on this. Great advice gentlemen ILL KEEP YOU POSTED ON HOW i GET ON. You know what this means-Now Ill have to make a visit to the junk yard to find an 8 inch diameter chimney from the fabricated heap -air duckting.:
Cheers Guys H&T.
I will post a picture of the blower soon as I take a picture of it.
