« Part 49: Scrolling brace for the wrist Part 50 of ScrollSaw Information and Resources series Part 51: How to Price your Scroll Saw work and sell it »

As I have been “scrolling” for four years and other various woodworking projects for over twenty years I seem to have developed more sinus issues than normal. YEs it could be just this year or my “older” age. However I have decided to take a longer look at the issue. I have somewhat of a dust control system (post in the projects section” plus a use a shop vac. on the table saw and router.

I was on the lookout for the DeWalt dust control unit that cost about $139 but is seems to be off the market. A little internet research led me to a post by a Professor at the Univ. of Michigan. The post is at He makes the point and demonstrates that a simple box fan and a quality air filter duck taped in from of it will do “almost” as good of a job as the more expensive systems.

Your thoughs, ideas and reflections would be of great help to these sniffles.

I think you would need a fan that can develop some static pressure or it will simply spin in place and pull very little air through the filter. I don’t know if a box fan like he shows would work well or not. Maybe somebody on LJ’s has has tried something like this or knows more about the subject and could chime in. If it pulls a fair amount of air through the filter that would be a great easy solution.

I got a little fancy and made a plywood box to set the fan in with a slot to slide the filter into. Going with
the theory that an exhaust fan works better than a suction fan, I put the filter on the input side of the
fan. There is a considerable breeze coming from the fan although the filter does cut it down a bit and the
filter collects a lot of dust, so yes it does work. I do not have a counter, nor do I use a merv 13 filter, but
it definitely clears out a lot of dust , and in combination with the dust collectors it helps keep the shop

Thanks Bluepine38. I was thinking of reversing the filter and fan – plus building a box for it. Seems like the system should, at least, help and you seem to say that it does.

Been using this system for many years, it works very well. I put a cheap filter on the input side and a good quality one on the output, there is still good air flow even with two filters. Since i sit while scrolling i have the fan hanging at head height about 4 ft to my left, i have the saws blower pointed in that direction. Scrolling produces very fine dust, so to help, i place a small desk fan slightly behind to my right on low. As i said, works very well.

There are LOTS of good ideas here on Lumberjocks. Just search “dust” and take a look. So many ideas, I can’t decide what to do!
