« Part 1: A serious dust extractor needs a silo Part 2 of Dust Extraction series Part 3: Metal Ducting »

Today my dusty died.

I was working on two toy chests for christmas. I was cutting the curve on the base moulding with a jigsaw I heard a clang, followed by a change in pitch of the dust extractor hum. My 3 week old dust extractor.

I cut the power and walked over to explore.

The impellar case was split… a ding in the curve… and some paint missing.

I found this block of wood. A little big for a dust extractor… about 20cm long. (Tells you it’s got some power.) I had the 4” flex hose sitting on my project next the jigsaw. It was doing a good job. Something moved and the hose fell to the ground… I didn’t think much of it and kept cutting. I didn’t think it would find an offcut below me.

I removed the hose mounting to explore inside. A single blade has been bent need flat.

So dusty is out of action for a while. Need a proper repair on this one.

Any tips on fixing it would be more than appreciated.

Sorry to hear about the impeller on your DC.

Never explored inside of mine, but maybe it will come off the shaft where you can get it to a bench for flattening back into shape??

I got one of those trashcan seperators just to avoid such an occurence. Works nicely and much easier emptying the can than removing the bag.

Since it’s trashed anyway, why not try to straighten out the bent blade? Vice grips come to mind…

I hadn’t thought about that, i’ve sucked up some big things also, i guess i need to add a secondary separator also, sorry you lost your dust collector. hope you can get it repaired.

I’d use a torch to heat up the blade where the bend is to make it pliable. It will also keep it from becoming brittle. Bending metal cold makes it harder and susceptible to breakage.

If it does break, it looks to be riveted in place. You could fashion one out of a similar metal. Balancing it would be crucial.

I would hesitate on using a torch till I was sure it is not made of pot metal (zinc) or once you put a bit of heat to it it will melt away like plastic. Try pliers or vise grips first, it does not look like it is that sturdy that you will not be able to bend it back into reasonable shape. Did you remove the protective screen from the intake area? I removed mine but I have a secondary trash can that everything goes to before going through the collector. I would highly recommend that you do this too.

I was sanding some small parts and one got away from me, it went into the dust collector, luckily no damage. After that I placed a piece of chicken wire with 1/2” spacing over my dust port and that solved that issue.

I would think about a separate chip separator then this would not happen again.

Good luck in fixing it.
