  • Enclosing all the "holes" in the BT3100 Cabinet

    Getting back into woodworking, and I remember seeing an article (I'm assuming on the old BT3Central site) where somebody enclosed almost all the "holes" in the saw's cabinet. IIRC, it had the "articulated dust port" cover and new plywood sides that basically only allowed air to come in the side where the motor is. I remember a picture of a small piece of plywood suctioned to the screen on the motor side. I can't find the article in the archives. Anybody else remember/saved it?

    If the write-up is indeed lost, are there any considerations other than "Don't block-off too much and allow the motor to overheat."?

    I think that post or article is still around.

    But I don't agree with it. You need places for the volume of air to get in that you are pulling with a dust collector. If you make a vacuum or dust collector pull on a nearly sealed box, nearly no air will flow.

    You want maximum flow of air by the dust producing spots to pick up and carry the dust away.

          I authored two articles concerning closing up the BT3K cabinet. My saw has been "closed" since 2000 with no ill effects. However, it is not totally closed. There is still some openings for air to be drawn in by the dust collection system. Everything else was sealed off with duct tape and still is. The front tilt quadrant is open and the various throat plates allow airflow also. I also attached 2" diameter disks of silicone sealant all over the interior of the sheet metal cabinet to quell vibration noise. One could also use Dynamat like material applied to the interior to do the same thing.

            Just IMHO, Mine uses the belly pan, zero clearance throat plates, and a Shark Guard with a 2.5" port, and in use offers a dust free experience as long as I remember to turn ON the dust collector. Yeah I have been dump about that from time to time...

              I forgot to add that I'm using a ShopVac (195 cfm) connected to the BT3000's dust collection port. The clean out port at the bottom of the belly pan fits a 1 1/2" vac hose and is plugged with a 35 mm film canister.

                Just FWIW, I haven't ever seen a belly pan with a small shop vac port. How well does that work?

                  The belly pan vac port is used to clear out what collects down there. I hook the shopvac hose to it and use a stick to sweep chips to the port. Crude, but it works for the couple of times a year when clean out becomes necessary.

                    A drawback to this saw is the universal motor trapped inside with all the dust. I would think that a better way to collect dust from inside the cabinets would be to fasten a shop vac hose near the blade rather than plugging all the cabinet holes. Combined with the shark guard it should be a clean running machine.

                      The BT3Ks have a shrouded blade and the vac port is part of the shroud. Hence the articulated vac port cover so the hose can move with the port while closing off the rest of the slot the port slides in. Checked the motor on my 1993 BT3000 last year and almost no dust inside the motor.
