I know there have been a lot of threads lately and I am sorry to be adding to the noise.. But I am lost. I have been reading(or trying to read) the more techincal documents and facts about it. Nothing seems to be straightforward. PVC is bad.. static... but its good because its smooth. 6 inch pipe is the way to go... or is it, you might loose velocity. Suffice to say I am not getting anywhere here on my own. So here is my situation.I am a youngin just getting into the hobby. I will have a small basement shop in my parents house for maybe a year and a half(until I am out of college), then my girlfriend(hopefully wife by then) will be moving in to our own house, and it will be small(I refuse to rent, big waste of money in my book, then again I am young and know nothing, buy I think its smarter to get a house sooner than later.) Anyway, my setup for the short and semi long term will be a small shop.
I have most of my large equipment already. I am trying to do things right. I have an old 2hp grizzly Dust collector, looks like the G1029's predecessor, it has a 5" inlet, and I don't know the CFM's but it can suck. I have a small shopvac for portable needs, and I would wear a respirator. The guy I bought my DC from said he would give me all his duct work, it is all 4". I will have to hook up my table saw, miter saw and I have a floor sweep I would like to put in. All would be within 6-8 feet of the DC and I want to run the pipe along the floor under my workbenches and support tables(that I plan to build). I think 4" ducts would be fine, but I wanted to get a more experienced opinion. When a tested my collector it seemed to blow harder when the 2 way 4" splitter was on opposed to being wide open, but I could tell a big difference when I closed one of the 4" openings. I plan on exhausting outside. What would you do?
