Squishy Miter Saw Shroud Spares You The Sneezy Bits

April 7, 2024 by Sonya Vasquez 8 Comments

Let’s be honest. When it comes to operating miter saws, these tools kick dust out the back like a spray paint can. Most of us have accepted this quirk as-is, but not [Inspire Woodcraft] who’s on a mission to achieve near perfect dust collection. And he nearly has it. With a budget dust collection setup, he’s able to eliminate over 90% of the dust from his cuts, and others who’ve adopted his setup can vouch for his results.

The solution comes in two pieces. First, he focuses on creating a new dust shroud or “boot” for collecting dust through the vacuum hookup on the back of the saw. What’s key here is that this dust boot is made from squishy silicone, enabling it to flare outwards and spread out as the saw travels downward into the material. It’s clear that [Inspire Woodcraft] has gone through dozens of material and shape iterations, but the result is sturdy enough to stay open with the vacuum running through the back hose attachment.

With the dust nearly perfectly funneled from the back, the second tweak focuses on rerouting stray dust away from the table and directly into this boot. [Inspire Woodcraft] later noticed that dust collection from the bottom of his miter saw simply didn’t exist, so dust would accumulate at his feet.

His solution? To create a second shroud that fits under the throat plate that takes sawdust once destined for the ground and ejects it backwards and straight into the dust collection boot.

Altogether, this setup solves a long-existing problem with a handful of commodity parts and a few 3D prints. [Inspire Woodcraft] has also chronicled his journey in such detail where you too could recreate his solution from the video. But if you’re feeling lazy, and you’re lucky enough to own the same Dewalt DW716 or DWS716 model miter saws, you can simply snag a kit from his website.

If all this talk of miter saws has your reaching for a screwdriver to see what modified mayhem you can unleash with yours, look no further than this LED hack that adds a shadow line to your cuts.

Impressive Sawdust Briquette Machine

January 16, 2023 by Anool Mahidharia 28 Comments

When you are a life long carpenter with an amazing workshop, you’re going to make a lot of saw dust, and managing its collection and storage poses quite a challenge. [Russ] from [New Yorkshire Workshop] built an impressive Briquette press to handle the problem.

It’s a hydraulic press that ingests saw dust and spits out compressed briquettes ready for fueling his rocket mass heater. The build starts with a batch of custom, laser cut steel parts received from Fractory. The heart of the machine is a 300 mm stroke hydraulic cylinder with a beefy 40 mm rod. The cylinder had to be taken apart so that the laser cut mounting flanges could be welded, slowly so as not to deform the cylinder. The intake feed tube was cut from a piece of 40 mm bore seamless tube. A window was cut in the feed tube and funnel parts were welded to this cutout. The feed tube assembly is then finished off with a pair of mounting flanges. The feed tube assembly is in turn welded to the main feed plate which will form the base of the saw dust container. The hydraulic cylinder assembly is mated to the feed tube assembly using a set of massive M10 high tensile class 10.9 threaded rods. The push rod is a length of 40 mm diameter mild steel bar stock, coupled to the hydraulic cylinder using a fabricated coupling clamp. On the coupling clamp, he welded another bracket on which a bolt can be screwed on. This bolt helps activate the limit switches that control the movement of the hydraulic cylinder and the feed motor.

This Dust Collector Will Blow You Away.

April 30, 2018 by James Hobson 7 Comments

As [Marius Hornberger] was working in his woodshop, a thunderous bang suddenly rocked the space. A brief search revealed the blower for the dust collector had shifted several inches despite being stoutly fastened down. Turns out, the blower had blown itself up when one of the impeller fins came loose. Time to revise and build a bigger, better dust collector!

[Hornberger] is thorough in describing his process, the video series chronicles where he went astray in his original design and how he’s gone about improving on those elements. For instance, the original impeller had six fins which meant fewer points to bear the operating stresses as well as producing an occasionally uncomfortable drone. MDF wasn’t an ideal material choice here either, contributing to the failure of the part.

Down-Draft Table Keeps The Shop Dust Free

June 23, 2015 by Rich Bremer 17 Comments

Wood working is great but it can certainly get the shop dusty. [BigD] is a wood worker and needed a way to keep his shop from getting super dusty while sanding or routing. He ended up making a pretty slick dual-use downdraft table with a hidden filtration system.

The table’s frame is made from standard 2-by dimensional lumber you’d likely see most shop tables made from. It was built so that the top of the table would be flush with the table of the table saw. This allows the down-draft table to also act as an out feed support for the table saw, making it easier to cut longer pieces of wood.

To allow airflow to pull any generated dust down, a plethora of holes were drilled in the table top. Down below are a couple sealed chambers, one for the incoming dust and one for the air blower that creates the down-draft air flow. The two chambers are separated by a pair of filters which keep the dust from being blown back into the shop. A little door on the side of the table allows access to clean out the accumulated dust and debris. Now [BigD] can sand up a storm on his down-draft table without breathing in a sapling worth of dust.

DIY Dust Cyclone A Traffic Cop Would Be Proud Of

April 26, 2015 by Rich Bremer 45 Comments

Sure, having a wood shop is super handy but it also can get real dusty. Hooking up a shop vac to suck up dust coming off a wood-cutting machine works for all of 3 minutes before the vacuum’s filter gets clogged with dust. There is a solution, though, and it is called a dust separator.

A dust separator does just as its name suggests, it separates dust from air. There is a common type of dust separator made in the DIY community, it has a cone-shaped body and is generally referred to as a cyclone-style. [Dror] built his own cyclonic dust collector out of an odd object… a traffic cone. Looking at it now, we wonder why this isn’t much more common!

The dusty air enters the PVC pipe and ends up spinning around the inside of the cone. Since the dust particles have mass, they are thrown to the outside of this chamber as they spin. They lose speed and drop down into the 5 gallon bucket below. The dust-free air then outlets through the top of the dust separator which is connected to a shop vac.

You’ll notice that [Dror] decided to use threaded rod to hold his separator pieces together. While this may seem like overkill, he had tried several glues and could not get any to stick to the traffic cone!

If you’d like to get in on the dust separator action but don’t have a traffic cone, they can also be 3D printed or made from metal.

DIY CNC Dust Collection Really Sucks!

CNC Routers are great. If you’ve ever used one you know this but you also know that they will cover the machine and everything around it with a layer of dust. It is certainly possible to use a shop vac to suck up the dust coming from the router, however, the only problem with that is the shop vac’s filter will clog with dust and lose suction, defeating the intent of your vac system.

[Mike Douglas] was ready to step up his CNC game and decided to make his own dust separator. This design is extremely simple and only uses a couple 5 gallon buckets, a few PVC fittings and pieces of wood. To keep the cost down and the style up, the accompanying ‘shop-vac’ is also made from 5 gallon bucket with a vacuum lid. The project is well documented so head over to his site and check out the build process.

Cyclone Dust Collector Requires No Bags Or Filters

February 24, 2014 by James Hobson 46 Comments

After discovering their dust collection vacuum was blowing through filters and leaking powdered fiberglass dust all over their workshop, the folks at i3Detroit decided to take matters into their own hands, and built this awesome cyclone dust collector that requires no bags or filters!

They were inspired by a similar wooden sawdust collector, but as they cut many different materials, they decided to build a steel cyclone for durability. The build makes use of two 5-gallon buckets, a 5-gallon vacuum cleaner, and a meticulously designed sheet metal cyclone cone. The vacuum creates a strong suction force and the dust enters the cyclone, getting sucked to the bottom and into the blue bucket. This keeps the filter in the vacuum clean, and keeps all the debris in an easy to access bucket. Continue reading “Cyclone Dust Collector Requires No Bags Or Filters” →
