Topic tags/keywords: dust collection

Okay – just got a dust collection system with a single hose that I’m trucking around my small shop to each tool.

For tools like the bandsaw and scrollsaw, I’ve made brackets that hold the hose under the deck, as close to the blade as I can get it.

Sounds great, but I’ve noticed that a lot of the dust on the deck surface actually gets blown back up!

Is this some weird backdraft thing? What in the actual hell.

Any thoughts or suggestions to avoid that?

What size dust collection system, 2-2.5” vacuum hose or 2-3HP+ system with 4”+ hose?

Are you using zero clearance inserts, or regular inserts? ZCI can help keep dust below deck where DC can take it away.

Size and volume matters when it comes to DC.

Will need pictures and more information on your DC method to provide any specific feedback?

As the Captain said (in more civilized words), a few pictures of your setup could benefit those of us that can’t mind read… I’m senile and grumpy, so please forgive.

Sorry for being blunt Ohio, but you’ll find many LJers are willing to help but many might not be familiar with described machinery/set-up and many being hobbyists, may have blundered through the same dillema you’re facing…

and amongst all that “outburst”, welcome to LJ.

Most new tools have a dust port built in. Older tools take some creativity to manage dust. This means research to see what others have done and you will need to do some fabrication. An open hose below deck will only be slightly better than laying it on the floor below the tool where the dust falls. You will need to create enough direction to move dust booth though the deck and away from any cutters.

It’s not clear to me what you mean by “deck”. Do you mean the saw table, or an outdoor surface with tools on it?
