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.

Could Moon Dust Help Reduce Global Temperatures?

October 10, 2023 by Lewin Day 66 Comments

The impacts of climate change continue to mount on human civilization, with warning signs that worse times are yet to come. Despite the scientific community raising an early warning as to the risks of continued air pollution and greenhouse gas output, efforts to stem emissions have thus far had minimal impact. Continued inaction has led some scientists to consider alternative solutions to stave off the worst from occurring.

Geoengineering has long been touted as a potential solution for our global warming woes. Now, the idea of launching a gigantic dust cloud from the moon to combat Earth’s rising temperatures is under the spotlight. However, this very sci-fi solution has some serious implications if pursued, if humanity can even achieve the feat in the first place.

Workshop Dust Manifold Spreads The Suction Around

July 26, 2023 by Lewin Day 15 Comments

Let’s say you’re doing lots of woodwork now, and you’ve expanded your workshop with a few big tools. You’re probably noticing the sawdust piling up awfully quick. It would be ideal to have some kind of collection system, but you don’t want to buy a shop vac for every tool. This simple manifold from [Well Done Tips] is the perfect solution for you.

It’s a basic rig at heart, but nonetheless a useful one. It consists of a plywood frame with a shuttle that slides back and forth. The suction hose of your shop vac attaches to the shuttle. Meanwhile, the frame has a series of pipes leading to the dust extraction ports of your various tools around the shop. When you power up a tool, simply slide the manifold to the right position, and you’re good to go. Magnets will hold it in place so it doesn’t get jostled around while you work.

It’s a much cheaper solution than buying a huge dust extraction system that can draw from all your tools at once. If you’re just one person, that’s overkill anyway. This solution is just about sized perfectly for small home operators. Give it a go if you’re tired of sweeping up the mess and coughing your lungs out on the regular. Video after the break.

Hackaday Links: January 15, 2023

January 15, 2023 by Dan Maloney 18 Comments

It looks like the Martian winter may have claimed another victim, with reports that Chinese ground controllers have lost contact with the Zhurong rover. The solar-powered rover was put into hibernation back in May 2022, thanks to a dust storm that kicked up a couple of months before the start of local winter. Controllers hoped that they would be able to reestablish contact with the machine once Spring rolled around in December, but the rover remains quiet. It may have suffered the same fate as Opportunity, which had its solar panels covered in dust after a planet-wide sandstorm and eventually gave up the ghost.

What’s worse, it seems like the Chinese are having trouble talking to the Tianwen-1 orbiter, too. There are reports that controllers can’t download data from the satellite, which is a pity because it could potentially be used to image the Zhurong landing site in Utopia Planitia to see what’s up. All this has to be taken with a grain of dust, of course, since the Chinese aren’t famously transparent with their space program. But here’s hoping that both the rover and the orbiter beat the odds and start doing science again soon.

Hackaday Links: November 6, 2022

Remember the chip shortage? We sure do, mainly because as far as we can tell, it’s still going on, at least judging by the fact that you can’t get a Raspberry Pi for love or money. But that must just be noise, because according to a report in the Straits Times, the chip shortage is not only over, it’s reversed course enough that there’s now a glut of semiconductors out there. The article claims that the root cause of this is slowing demand for products like smartphones, an industry that’s seeing wave after wave of orders to semiconductor manufacturers like TSMC canceled. Chips for PCs are apparently in abundance now too, as the spasm of panic buying machine for remote working during the pandemic winds down. Automakers are still feeling the pinch, though, so much so that Toyota is now shipping only one smart key with new cars, instead of the usual two. So there seems to be some way to go before balance is restored to the market, but whatever — just call us when Amazon no longer has to offer financing on an 8 GB Pi.

Plastic Strips Protect Ball Screws On This Homebrew CNC Router

October 26, 2020 by Dan Maloney 17 Comments

It’s a fact of life for CNC router owners — swarf. Whether it’s the fine dust from a sheet of MDF or nice fat chips from a piece of aluminum, the debris your tool creates gets everywhere. You can try to control it at its source, but swarf always finds a way to escape and cause problems.

Unwilling to deal with the accumulation of chips in the expensive ball screws of his homemade CNC router, [Nikodem Bartnik] took matters into his own hands and created these DIY telescopic ball screw covers. Yes, commercial ball screw covers are available, but they are targeted at professional machines, and so are not only too large for a homebrew machine like his but also priced for pro budgets. So [Nikodem] recreated their basic design: strips of thin material wound into a tight spring that forms a tube that can extend and retract. The first prototypes were from paper, which worked but proved to have too much friction. Version 2 was made from sheets of polyester film, slippery enough to get the job done and as a bonus, transparent. They look pretty sharp, and as you can see in the video below, seem to perform well.

It’s nice to see a build progress to the point where details like this can be addressed. We’ve been following [Nikodem]’s CNC build for years now, and it really has come a long way.

Custom Coaxial Dust Collector Makes CNC Router A Clean Machine

September 1, 2018 by Dan Maloney 24 Comments

Everyone loves firing up that CNC router for the first time. But if the first thing you cut is wood, chances are good that the second thing you cut will be parts for some kind of dust shroud. Babysitting the machine and chasing the spindle around with a shop vac hose probably isn’t why you got it in the first place, right?

Trouble is, most dust-management designs just don’t get the job done, or if they do, they obstruct your view of the tool with a brush or other flexible shroud. [Jeremy Cook] figured he could do better with this coaxial dust collector, and from the practically dust-free cuts at the end of the video below, we think he’s right. The design is a two-piece, 3D-printed affair, with a collar that attaches to the spindle and a separate piece containing the duct. The two pieces stick together with magnets, which also lets the shroud swivel around for optimal placement. The duct surrounds the collet and tool and has a shop vac hose connection. In use, the vacuum pulls a ton of air through small opening, resulting in zero dust. It also results in the occasional part sucked up from the bed, so watch out for that. [Jeremy] has published the STL files if you want to make your own.

We’re pretty impressed, but if you still feel the need for a physical shroud, check out this shaggy-dog design that seems to work well too. Or you could just throw the whole thing in an enclosure.
