I am close to completing my new shop. Putting in the Harvey 700 dust extractor with 6” inlet. The local price for 6” sdr pipe and fittings just for main runs and drops, no blast gates hose or machine connections is 1150 at the best wholesale. Looking at Oneida the cost for 6” main and 5 drops and fittings spiral pipe and adjustable elbows not clamp type is about 1200 plus shipping. Will 6” drops with 5” machine connections work if I go all pvc. Machines are 20” planer, 8” jointer, k3 slider, 17 band saw with 2-4”, 5” connection edge sander and 4” router table. Thoughts. All 6 pvc or 6 and 5 metal
thanks
