    Gregg,

    It's always a tough choice when you have some spare cash and are trying to get the most "bang-for-the-buck" to evolve your shop. On the one hand, you can upgrade your current machines, and...

    One more point Paul,

    Increasing the airflow at the base when you're not using the overarm guard, is redundant. You're obviously going to set-up your pipes in such a way that you'll be getting all...

    Paul,

    Whenever you operate both legs of a wye, the static-pressure in both branches will balance automatically. For example, a 6x4x4 wye pulling a total 800 CFM, will draw 400 CFM through each...

    Hi Chris,

    I'm presuming the 3-wing cutters would...

    Hi Stephanie,

    If your hubby is in on this project, have him contact me, and I'll be more than happy to help him design his lay-out. If it's a surprise, then I'll need some information from you.

    Tony,

    One of the best articles I've ever read regarding "drift", was written by Jim Cummins in Taunton Press' "Power-Saws and Planers". It's an excellent read. I believe the article is titled...

    Glen,

    You can reduce the CFM penalty somewhat when using those "lid" systems. Basically, you have two ways of dealing with that.

    Either you use a large-drum, with a shop-built lid and...

    Tom,

    Seems to me I saw a comparison somewhere a few years ago. Of the trash-can cyclone lids, apparently the Lee Valley version was the best.

    I use a GreenLee which I bought at Grainger, but it's probably a little too pricey for what you want. It clamps around one of the "hot" wires.

    Chris,

    You can insert one anywhere along one or more of your drops, you don't have to start from the main. For example, a wye placed close to your saw, would give you that capability. Floor-sweep...

    I think you're right Jim. Seems to me I also saw someone say that they've added a neutral vane. I don't recall exactly.

    These guys were also selling two sizes of passive cyclones. Seems to me one...

    Tim,

    I agree wholeheartedly with Terry. You'd be taking a step backwards with the small cyclone. From what I recollect, it has a 4" intake doesn't it? The original plan called for a 1 1/2 HP Penn...

    A 4" port on most cabinet saw bases is "more than enough", but, it depends on how it's configured and piped.

    That's an interesting situation. If your friend cut his fingers, then there was no overarm blade-cover on his saw; correct?. The dc would only be collected to his saw-base, right? I'd...

    John,

    Dust collection can basically be divided into two components; 1. The amount of air you want to move at your machines, and 2. The filtration stage.
