Build a Better 5-Gallon Bucket Dust Separator! 

First-stage dust separators have been improving shop vacuum performance for years, but many systems rely on expensive components, specialized containers, and complicated hardware that can quickly drive up the cost. Infinity Tools offers a simpler and more affordable approach. 

Pair the Infinity Tools 115-279 DIY Dust Separator with your own standard 5-gallon bucket and you have the foundation for an effective, economical shop vacuum dust collection system. Add the Infinity Tools 115-278 Dust Separator Lid Stiffener, and you have a strong, durable mounting surface designed specifically to support the separator. 

Precision CNC milled from 1/2"-thick MDF, the 115-278 lid stiffener reinforces the top of your 5-gallon pail while providing a robust mounting location for the dust separator. Simply attach the stiffener to your bucket lid, cut the required center opening, and install the 115-279 dust separator. 

The result is a straightforward DIY dust separator system that uses an inexpensive, readily available 5-gallon bucket as the collection container. Instead of investing in a costly dedicated dust collection system, you can create an efficient first-stage separator using components designed to work together. 

The reinforced lid helps provide the rigidity needed for a secure separator installation, while the replaceable bucket keeps the system economical and easy to maintain. When the collection bucket fills, simply empty it and put it back to work. 

Whether you're upgrading a shop vacuum dust collection system, building a DIY woodworking dust collector, or simply looking for an inexpensive way to separate sawdust and chips before they reach your vacuum, the 115-278 is a smart addition.

Frequently Asked Questions

What is the DIY Dust Separator Lid Stiffener made of?

It's a precision CNC-milled 1/2" thick MDF stiffener (part 115-278) that reinforces the lid of a five-gallon bucket. See more dust collection gear.

What does the lid stiffener do?

It strengthens a five-gallon bucket lid so it can serve as a robust mounting location for a first-stage dust separator, keeping the separator stable and in use for a long time.

What separator does it work with?

It's designed to pair with the Infinity 115-279 dust separator mounted on your own five-gallon bucket for a cost-effective first-stage setup.

How do I install it?

Attach the stiffener to your bucket lid and cut out the center hole. That gives you a robust mounting spot for the separator — simple and cost-effective.

Why use a DIY separator instead of a commercial one?

Many first-stage separators use expensive components that make them costly for what they are. Pairing this stiffener and the 115-279 separator with a bucket you already own is a much more affordable solution.

Does the bucket come with the stiffener?

No. The stiffener is designed to pair with your own five-gallon bucket, which keeps the overall cost down. You'll also want dust collection fittings to connect it.

Who makes the lid stiffener?

It's made by Infinity Cutting Tools and carries part number 115-278. Explore more dust collection products.

How thick is the stiffener?

It's 1/2" thick CNC-milled MDF, giving the bucket lid enough rigidity to support the separator securely.

Will it make my separator last longer?

Yes. By providing a robust mounting location, the stiffener helps keep the separator in stable use for a long time to come instead of flexing or failing at the lid.

What else do I need to finish the setup?

Beyond the stiffener, separator, and bucket, you'll want the right hose and fittings. Browse our hoses & accessories and dust collection fittings.
