Ok so I've been racking my brain over this 4" vs 6" dust collection. I have a HF 2HP DC and I'm planning on a Wynn filter and Thien Baffle. I priced out PVC and I am NOT paying $35 per 10 foot section for 6". I have a small shop, just 20 x 20. Would 4" work or do I need to look into stovepipe for 6"? I will have 6 runs all together, the longest being about 35 feet. Trying to do this on a budget because I need to get it done quick and just don't have the time to save up and do what I would like.
