    I just checked the HP (which is misleading, it's the amperage that counts.) I'm using an older Sears which has an rating of 11.6 amps, and the HP rating of 5 HP (yeah, right).

    What IS important is that you keep the vacs filter as clean as possible and never let the container get more than a third to a half full. A dirty clogged filter can have a major impact on the "sucking" power of your vac. An incorrect (or in some cases, any) extension cord (I don't use one) will reduce the power of your vac. dramatically.

    If I had the room, I'd be using a proper dust collection system instead. Shop Vacs aren't the best way to collect saw dust from woodworking machines.

    In answer to Davidtu's question, what both Loring and I are referring to, is the "built in" dust collect port at the rear of the saw. We aren't doing anything special in the way of "tricking out" the saw to help in dust collection.

    Some saw dust will always be floating around the shop, that's a fact of life, after all, we're not talking about "clean room" conditions here.

    I have found that a ZCTP does hamper dust collection, but I'd much rather deal with the dust than the splintering of stock.

    I always wear a dust mask when cutting MDF, its dust is more like talcum powder than saw dust. Also, some tropical wood saw dust borders on being poisonous, and in that case, I wear a respirator when cutting this type of wood.

    Bottom line, I found that the "above the blade" collection method that Lee uses in his Shark Guard does more than drilling holes in your ZCTP. In all probability, you'd get better collection with a "standard" throat plate/Shark Guard combination, but as I mentioned earlier, a ZCTP is in my opinion mandatory, as is the Shark Guard.

    Hope this answers your questions (both of you), just keep at it and dust or not, enjoy woodworking, that's whats most important (sorry Rod), I much rather have a messy shop than limiting my fun and creativity (or lack of) in the shop.

      My simple dust collection "belly pan" gets everything inside:

        There have been other discussions on this in the past. For example,

          Hey Loring, just to clarify your pic, it looks like your are running a hose from the blade shroud and another from your belly pan, right? Did the pan appreciably improve the efficiency. Here's why I ask. I'm using a Ridgid 3650 and removed the shroud and installed a 4" toilet flange (my take on the belly pan) and noticed that I get a lot more dust escaping from the drive belt, etc holes. I was pretty well set on switching back but maybe the combo will do the trick. Are you also using the Shark? That would be a lot of plumbing!
          TIA,

            yes.

            The original scheme, hose on the blade shroud port allowed a lot of dust to accumulate around the inside of the saw and also fall to the ground below. Now, the inside is clean as a daisy. or maybe that's a whistle ?

            I have a Shark Guard but have not plumbed the blade guard yet. I've comptemplated it but that WOULD be a lot of plumbing.

              Steve is right to worry about dust exposure. Wear a mask (and goggles and ear protectors). Spend good money on it, your lungs never recover from the super fine dust you pump into them during normal woodworking procedures. It's almost like smoking. Dust kills. If not you, directly, your family, pets and kids, indirectly. Talk to any medical professional - woodworkers often have scarred lungs and they go half deaf at high rates. Go to any woodworking convention or club meeting - hearing aids are everywhere. Upper respiratory ills are common too.
