 :) Thank you for your comments. Sounds like I need to follow your recommendations and go with 6" diameter.
Thanks again.

Hello there...brand new to this blog, but have been reading all the posts and almost finished this project. Have not turned it on yet, not quite there. I am using 4 inch diameter dimensions for duct and hose. My question to you folks is (that I may have been lazy), is this going to be OK for performance? Or, should scrap the 4 and go to the 6. I would rather stay with 4" but not at the cost of losing drastic performance. I notice that most have used 6". I have a Delta 50-760, 1.2 HP, 1200 CFM. Thanks for any replies.
