Thanks for all the input and feedback fellahs -

Hi Pat – Can I first say, that although I mentioned “T” shaped, the junction where the branch meets will be made up of two 45degree couplings ensuring a wide smooth curve rather than a tight 90 degree bend The ducting will be on the same plane, rather than the top branch being horizontal and the stem being vertical. The branches to the individual machine will have “Y” connections rather than “T”’s. and will only be about 3’ long at most. I will have very little in the way of the ribbed hose, only using it where I cant manouver the ducting to fit

Monte Cristo – I have a couple of books on dust collection, the advice from bothh seem very sound and I have gleened much of what I know from them. However, the books rarely have the answers to problems or issues encountered by individual systems, hence my post here (which I have to say has proved more efficient than any book).

Loren – I might have a look at the WOOD magazine cyclone plan. I have the WOOD magazine dvd (up till 2008) do you know which magazine issue the plan featured??

DJG – You have provided a lot of info there, thank you. Not sure I have the technical understanding of air flows to make the most of what you have contributed though. My DC has a 6” port on the impeller housing. Fitted to that is/was a coupling with two 4” ports formed in a Y section. I have removed this fitting with the two 4” ports. My thinking was to run a 6” duct (approx 3 feet from the DC to the collector. Th remainder of the system will be 4 1/2” drainage pipe. I take your point that there may be no great benfit by using 6” ducting to the collector (50 gallon drum) but surely it won’t have a negative effect?
The BS is sited approx 4 feet from the DC so shouldn’t have too much trouble “sucking” the dust at the BS?
I can’t remember off hand ,although I believe my DC is good for 1100CFM I’ll have to check that. What other info would you require of the DC to provide some more info, Amps? circumference of the impeller etc?

Stephen – That would be very kind, although if you don’t have the details can you remember what issue of the mag the plan was in…..no point in buying it if I already have it on WOOD mag dvd somewhere.
I have a plan from ShopNotes on how to build a cyclone, if you have seen it, is it anything like the plan you built your system from?

Thanks again

David
