   Huck, I found that website shortly after posting my initial question. I'm sure it collects "some" dust but just how much is what I'm wondering. I want to cut up a lot of MDF pieces and it's generating a lot of dust right from the start. That dust is so fine. I don't mind wearing a dust mask but it's the dust that's going airborne is what I'm concerned about.

   whoa!  That's a world apart from "i've thought about rigging up some kinda 'box' around the back of the saw to keep the dust contained"

   What you're asking for could only be handled by a sophisticated dust collection system, the kind made for a furniture or cabinet shop.  Google "shop dust collection"

   You might also want to google "dangers of mdf dust"

   I've built boxes to go behind the 716, I usually throw them together with scraps of 3/8 subfloor left over from the underlay job.

   I have built better quality ones, but they all bit the dust as they became a pain to transport.

   It's pretty simple, measure the saws operating reqirements by swinging the saw back and forth up down tilt etc. and build a box with some room to spare. The top should overhang the saw a bit, you'll understand why when you use it. You can always modify the thing with bits of cardboard etc after its built.

   I cut a hole in the back for the hose of my portable extractor as the box is pretty much useless without a blower. A vaccum might work, but a 1200cfm blower even sucks th dust from in front of the saw. It's kind of neat to watch that little cloud of MDF dust hover and then get sucked back into the box.

   I usually run a garbage can between the saw hose and the extractor, the blower screen gets plugged up quickly if you don't. Also make sure the bag has a small micron reading othewise, the fine stuff will get blown back into the air.

   huck, there's one company up here in Canada that sells that thing and it sells for over $200. My problem is this - 1. Money is tight for me this time of year & 2.A customer is waiting this week for things I have to cut up on my saw out of mdf so I'm kinda in a bind here. I could probably make some kinda box as I have lots of material lying around.

   Recommend you use in conjunction with shop vac and dust mask.  MDF makes a LOT of dust!  Even careful placement of jobsite fans to control air flow away from miter saw operator.View Image â€œGood work costs much more than poor imitation or factory product” – Charles GreeneCaliforniaRemodelingContractor.com
