and then building a plenum/dist. box out of MDF to split it up into the (3) 4" runs to do the whole shop

Bad idea. A box will kill your airflow. Ideally, you'd want to run 6" the length of your runs, and only drop to 4" if you have to. Keep the runs as straight as possible.

Not sure how I'm going to be able to afford to do it any other way right now... Having custom made sweeps and reducers could get pricey....

Here's kinda what I had in mind.....

You should be able to find a T-Y instead of making one... Nice buy, looking ot get one soon as well.

Mine is the green version. Keep an eye out for sales on these. I found it for $275 last year and jumped on it. (Probably won't see that again) You need hearing protection if it is not in another closed room. There is a DIY separator plate somewhere online that will fit it with a little modification to the drawing. I haven't made one yet, but need to find the web page again.

That's a really good price seeing as they charge $200 just for the filter canister... I paid $395 which is $50 off regular price...

Yeah, it's in another room...

Thanks for the tip Gerry... Ran 6" throughout the shop, and this was definitely the hot ticket.. makes sense to me now..... Thing works great...
