What Scale?

and what are the overall prototype dimensions you want to match?

Dust Collector

Phillip - The scale is HO and it wants to be the same as the one shown in attached picture. The one in the picture is from the Walthers Planing Mill and Shed kit 

Maybe start with this?

Try the cake decorating section at Michaels

Cyclone

Yes I have already looked at these, since I have 6 complete kits, but they are I feel to small for the storage bin. But maybe could set it up using two of them. I did just a possible solution I contacted Walthers to see if I could buy just this set of parts. They are going to check and let me know. I really don't want to buy the full kit - just to expensive just for the cyclone. But good thought.Thanks

Cyclone Dust Collector

Thanks Joe for the Michael's idea hadn't thought of them. I will check them out. Do have the Rix kit but it is really way to big.

Epic photo posting fail.....

...don't forget Plastruct.

Don't forget Plastruct. They have all sorts of cones, pipes, sheet stock, etc. If you can't find something there that is directly suitable, they have the materials to make what you need.

....and don't forget the Dollar Stores, they are great sources as well.

What's the trouble?

So, what's the error you're getting?
