Woodworker Goes From 3D-Printing Skeptic To Believer

December 20, 2018 by Dan Maloney 30 Comments

If there’s one place where the old ways of doing things live a longer life than you’d otherwise expect, it’s the woodshop. Woodworkers have a way of stubbornly sticking to tradition, and that usually works out fine. But what does it take to change a woodworker’s mind about a tool that seems to have little role in the woodshop: the 3D-printer?

That’s the question [Marius Hornberger] asked himself, and at least for him, there are a lot of woodworking gadgets that can be 3D-printed. [Marius] began his journey into additive manufacturing three years ago as a skeptic, not seeing how [Benchy] and friends could be of any value to his endeavors. But as is often the case with a tool that can build almost anything, all it takes is a little ingenuity to get started. His first tool was a pair of soft jaws for his bench vise. This was followed by a flood of useful doodads, including a clever center finder for round and square stock, custom panels for electrical switches, and light-duty pulleys for some of the machines he likes to build. But [Marius] obviously has an issue with dust, because most of his accessories have to do with helping control it in the shop. The real gem of this group is the hose clamp for spiral-reinforced vacuum hose; standard band clamps don’t fit well on those, but his clamps have an offset that straddles the wire for a neat fit. Genius!

[Marius] has kindly made all his models available on Thingiverse, so feel free to dig in and start kitting out your shop. Once you do maybe you can start building cool things like his all-wood scissors lift.

3D Printed Magnetic Dust Port Keeps Shop Clean

August 29, 2018 by Tom Nardi 33 Comments

Too often we hear that 3D printing is at best only a way for making prototypes before you invest in “real” manufacturing. At worst, it’s a way to make little toys for your desk or cubicle. The detractors say that 3D printing doesn’t lend itself to building practical devices, and even if you do manage to print something useful, you probably could have made it faster or better with more traditional manufacturing methods. So naturally we’re especially excited when we see a printed design that manages to buck both criticisms at once.

Not only does this magnetic dust port connector created by [Taylor Landry] have a clear practical purpose, but its design largely defies normal construction techniques. It consists of two flanges, sized for common 4″ flexible ducting, which feature embedded magnets on the faces.

This allows the two sides of the coupling to easily be connected and disconnected without relying on threads or a friction fit. Not only would threads likely get caked with sawdust, but the magnetic connection allows the coupling to release in the event somebody trips on the duct or the tool is moved.

Currently only one type of coupling is available, but [Taylor] says he’s looking at adapting the design to other tools. He also mentions that the magnets he’s currently using are a custom size he had left over from a previous project, so if you’re looking to replicate the design you might need to tweak the magnet openings. Luckily, he’s provided the STEP files so you don’t have to hack the STL.

A quick connect dust port like the one [Taylor] has come up with seems like it would be a perfect addition to the whole-shop dust collection systems we’ve covered in the past. In fact, it might not even be the only 3D printed component in the system.

Automatic Dust Collection For The Whole Shop

January 5, 2018 by Tom Nardi 19 Comments

If you’ve got a woodworking area, or even if you’ve just got something that really churns out dust like a belt sander or table saw, there’s an excellent chance you hate sawdust with a passion. It gets all over your clothes, jams up everything mechanical, and as a fun little bonus can be explosive if not handled properly. Thankfully newer tools tend to come with their own dust collection bags (back in the old days, you weren’t really a man unless you were coughing up wood fibers), but if you’ve got a half a dozen tools with half a dozen different dust bags you’ve got to empty, that can get pretty annoying.

Especially if you take woodworking as seriously as [Brad Wright] does. Over on his YouTube channel [DIY Builds], he quickly runs through the construction of a whole-shop dust collection system with some very neat features. Not everyone needs a system this intricate, but the tips and tricks he shows off during the build are great and can certainly be adapted to less grandiose setups.

Dust collection connector with closeable gate — One of the scratch-built gates.

[Brad] goes into a bit more detail in this gallery, revealing that the heart of the build is a Harbor Freight dust collection system that he modified into a cyclone separator. Big chunks fall down into the 55 gallon bucket, and what’s left gets blown out of the shop via a louvered vent through an exterior wall. An intricate system of 4 inch PVC pipe is then used to connect up each individual machine’s dust collection port. Even individual hand sanders get into the act via a three way manifold. His table saw lacked a dust port, so he enclosed the motor with a piece of plywood and made his own.

One of the most interesting aspects of the build is the scratch-built blast gates. These are essentially valves which open and close the different sections of the PVC where they mate to the individual stations. This prevents the dust collection system from wasting suction by trying to pull from all the stations at once when only one is in use at any given time. [Brad] even wired up the blast gates with switches that will turn the dust collection system on when the gate is open, and off when it’s closed.

This isn’t the first time we’ve covered the lengths people will go to rid their shop of dust. Cyclone dust separators are an especially popular build, using everything from sheet metal to 3D printed parts.

The Internet Of Blast Gates

December 11, 2017 by Brian Benchoff 22 Comments

There’s nothing quite like building out a shop filled with tools, but even that enviable task has a lot of boring work that goes into it. You’ve got to run power, you’ve got to build benches, and you need to build a dust collection system. That last one is usually just fitting a bunch of pipe and tubes together and adding in a few blast gates to direct the sucking of your dust collection system to various tools around the shop.

For most shops with a handful of tools and dust collection ports, manually opening and closing each blast gate is an annoying if necessary task. What if all of this was automated, though? That’s what [Bob] over on I Like To Make Stuff did. He automated his dust collection system. When a tool turns on, so does the vacuum, and the right blast gate opens up automatically.

The first part of this build is exactly what you would expect for installing a dust collection system in a shop. The main line is PVC sewer pipe tied to the rafters. Yes, this pipe is grounded, and s otherwise not very interesting at all. The real fun comes with the bits of electronics. [Bob] modified standard blast gates to be servo-actuated. Each individual tool was wired up to a current sensor at the plug, and all of this was connected to an Arduino. With a big ‘ol relay attached to the dust collection system, the only thing standing in the way of complete automation was a bit of code.

This project is a continuation of [Bob]’s earlier Arduinofication of his dust collection system where all the blast gates were controlled by servos, an Arduino, and a numeric keypad. That’s an exceptionally functional system that gets around the whole ‘leaning over a machine to open a gate’ problem, but it’s still not idiot-proof – someone has to press a button to open a gate. This new system is, for the most part, completely automatic and doesn’t really require any thought on the part of the operator. It’s neat stuff, and a great application of cheap Arduinos to make shop life a bit easier.

Overhead Trolley Helps Clear The Air Over CNC Router

July 8, 2017 by Dan Maloney 10 Comments

[Frank Howarth] has a shop most woodworkers would kill for, stuffed with enough tools to equip multiple hackspaces — four radial-arm saws alone! But while the CNC router in the middle of the shop, large enough to work on an entire sheet of plywood, is a gem of a machine, it was proving to be a dusty nightmare. [Frank]’s solution was as unique as his workspace — this swiveling overhead dust extraction system.

The two-part video below shows how he dealt with the dual problems of collection and removal. The former was a fairly simple brush-bristle shroud of the type we’ve featured before. The latter was a challenge in that the size of the router’s bed — currently 8′ but soon to be extended to 12′ — and the diameter of the hoses needed to move enough air made a fixed overhead feed impractical. [Frank]’s solution is an overhead trolley to support the hoses more or less vertically over the router while letting the duct swivel as the gantry moves around the work surface. There were a few pitfalls along the way, like hoses that shorten and stiffen when air flows through them, but in the end the system works great.

Chances are your shop is smaller than [Frank]’s, but you still need to control the dust. This dust collector for a more modest CNC router might help, as would this DIY cyclonic chip separator.

Clear The Air Around Your CNC Router With A Custom Dust Shroud

December 18, 2016 by Dan Maloney 11 Comments

Using a CNC router is a dusty business if your material of choice is wood. Sure, you can keep things tidy by chasing the cutter around the table with a shop vac, but that sort of takes the fun out of having a machine that can make cuts without you. The big boy machines all have integrated dust collection, and now you can too with this 3D-printed CNC router dust shoe.

Designed specifically for the X-Carve with a DeWalt 611 router, [Mark Edstrom]’s brush is a simple design that’s almost entirely 3D printed. The shroud encloses the router body and clamps to the mounting bracket, totally surrounding the business end of the machine. The cup is trimmed with a flexible fringe to trap the dust and guide it to the port that fits a small (1-1/4″ diameter) shop vac hose. The hose is neatly routed along the wiring harness, and the suction is provided by a standard shop vac.

Files for the cup are up on Thingiverse; we suspect it’d be easy to modify the design to work with other routers and dust collectors. You might even find a way to shroud a laser cutter and capture the exhaust with a DIY filter.

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.
