Best Miter Saw Dust Collection Hood | Woodworking Tips


Hi I’m Scott I design build and repair
woodworking pieces I’m opening up the doors to my shop to help you become a
better woodworker I know two retired wood workers who have
permanent lung damage because of the sawdust they breathed in over the years.
That’s why I pay a lot of attention to sawdust in my workshop This is the power tool that I use that most frequently creates dust in my shop and because of
that 15 years ago I build this dust collection system. Now I’ve looked for
other solutions out there but I haven’t found anything that I think is as
effective as this. I’m going to show you what I built here in hopes that you
will do something the same in your workshop and help protect your lungs. Effective dust collection is all about managing airflow what I have here is a
very narrow opening and because I’ve got a narrow opening my dust collector has a
lot of suction and power to pull air from where I don’t want it to where I do
want it so as I’m creating dust here the airflow
will pick up those particles and suck them inside If I’ve got a wide opening
like this I don’t have the power and the suction to be able to pull the dust from
out here and around the saw base into the unit Let me show you a few examples
of how this works [dust collector starting up] Now that you’ve seen how important it is
to have a small opening let me show you how I built this unit. It’s a basic box
sitting on a flat surface in my case I built my miter saw into a torsion box but any flat surface will do The important part is how to make these doors as narrow as possible when you need to make your cuts So what I’ve done is I’ve set in just a
simple track that the doors slide in and put them just behind the fence and just
above the table that way I can adjust the doors for a cut I need to make If I need to make a miter, I reduce those doors down as small as possible that way
I’ve got the most suction I can get at a given cut I can show you a few cuts here
and you can see how well it works at various angles [miter saw cutting through wood] This box is hooked up to the dust
collector through a spiral duct here this goes inside the box where I’ve got
to pick up The pick up here is part of a Y joint. Now this box was making up about 90%
of my dust collection but there was still a little bit missing so this Y
goes down continues underneath the table and pulls from underneath. Let me show
you I found that when I was making long
12-inch cuts I needed to be able to pull more dust from the front here and that’s why I added this pick up at the front
underneath the table This picks up most of the dust out here whereas when I’m making shorter cuts and standard cuts back here it’s the box
that’s doing the work To make your own dust collection system here the key to success you need to make sure you’ve got enough airflow so use a 1 to
2 horsepower dust collector Build a box and seal all the air gaps except for the
front doors install those front doors on sliding grooves to make sure they’re
easy to move back and forth and adjust Install the doors just above the saw
table and behind the fence Then test different pieces and tweak the design as needed I hope this gives you a good idea on how you can set up a dust collection
system for your miter saw If you’d like to see more videos like this please
