This DIY Drill Press Is Very Well Executed

September 22, 2020 by 22 Comments

Plenty of projects we see here could easily be purchased in some form or other. Robot arms, home automation, drones, and even some software can all be had with a quick internet search, to be sure. But there’s no fun in simply buying something when it can be built instead. The same goes for tools as well, and this homemade drill press from [ericinventor] shows that it’s not only possible to build your own tools rather than buy them, but often it’s cheaper as well.

This mini drill press has every feature we could think of needing in a tool like this. It uses off-the-shelf components including the motor and linear bearing carriage (which was actually salvaged from the Z-axis of a CNC machine). The chassis was built from stock aluminum and bolted together, making sure to keep everything square so that the drill press is as precise as possible. The movement is controlled from a set of 3D printed gears which are turned by hand.

The drill press is capable of drilling holes in most materials, including metal, and although small it would be great for precision work. [ericinventor] notes that it’s not necessary to use a separate motor, and that it’s possible to use this build with a Dremel tool if one is already available to you. Either way, it’s a handy tool to have around the shop, and with only a few modifications it might be usable as a mill as well.

A French Cleat Twist On Electronics Bench Organization

May 18, 2020 by 38 Comments

For some of us, our workbench is where organization goes to die. Getting ready to tackle a new project means sweeping away a pile of old projects, exposing exactly as much bench space needed to plop down the new parts. On the other end of the spectrum lie those for whom organization isn’t a means to an end, but an end itself. Their benches are spotless, ready to take on a new project at a moment’s notice.

[Eric Gunnerson]’s new French-cleat electronics bench is somewhere in between those two extremes, although nowhere near as over-organized as the woodworking organizer that inspired it. If you’ve never heard of a French cleat, Google around a bit and you’ll see some amazing shops where the system of wall-mounted, mitered cleats with mating parts on everything from shelves to cabinets are put to great use. A properly built French cleat can support tremendous loads; [Eric]’s system is scaled down a bit in deference to the lighter loads typically found in the electronics shop. His cleats are 2″ x 3″ pieces of pine, attached to a sheet of plywood that was then screwed to the wall. His first pass at fixtures for the cleats used a Shaper Origin CNC router, but when that proved to be slow he turned to laser-cut plywood. The summary video below shows a few of the fixtures he’s come up with so far; we particularly like the oscilloscope caddy, and the cable hangers are a neat trick too.

What we like about this is the flexibility it offers, since you can change things around as workflows develop or new instruments get added. Chalk one up for [Eric] for organization without overcomplication.

Custom Drill Press Table Eliminates Hassles

March 29, 2020 by 7 Comments

Getting a perfect workshop together, with all the right tools, is a dream for many. A lot of us cobble together what we can with a dremel tool, a soldering iron, and whatever work surface happens to be available in the kitchen or spare bedroom. But even when we finally get a permanent garage or shop to work in, there are still some challenges to overcome with our workspaces. [Workshop From Scratch] was having issues with his drill press, and solved them with this custom build.

Rather than modify an existing press, he first welded a table together from scratch using square tube. From there he set about solving those issues. The first was having to make a large number of adjustments up and down when working on larger pieces. For that he added an electrically adjustable worktop which keeps him from having to make constant adjustments of the press itself. The second improvement over the standard press workspace was adding a cooling system for the cutting tools, saving himself money in bits and allowing quicker drilling.

The finished product looks professional thanks to a quality paint job and, of course, having all the right tools in the workshop in the first place to put something like this together. We all have an idea in our heads about the perfect workshop for our own needs, but don’t forget to think outside the box when it comes to building one yourself.

Spring Clamp Is Completely 3D Printed

January 23, 2020 by 7 Comments

Dual-filament printers may seem like a gimmick to the uninitiated, but they open up some powerful options for advanced designs. [Darren Tarbard] shows this off with a nifty spring clamp that is 3D printed in a single operation.

The clamp is similar to one you’d find at any hardware store. Standard PLA or ABS filaments can be used for the main body of the clamp, which has an integrated hinge. However, instead of having a typical metal spring, the element is instead 3D printed. The spring is created out of TPU filament, and printed in place. Different in-fill percentages on the spring component can vary the characteristics of the spring, making for a softer or firmer grip.

It’s a tidy example of the applications of dual-filament printing – and far more useful than using it to print bi-color Pikachus. 3D printers have much to offer in the world of tooling; they can even turn a bench vice into an effective press brake. Video after the break.

Build Your Own Tools For More Power

December 3, 2019 by 19 Comments

Building something on your own usually carries with it certain benefits, such as being in full control over what it is you are building and what it will accomplish, as well as a sense of pride when you create something that finally works just the way you want it. If you continue down that path, you may eventually start making your own tools to help build your other creations, and if you also have some CAD software you can make some very high quality tools like this belt grinder.

This build comes to us from [Emiel] aka [The Practical Engineer] who is known for his high quality solenoid engines. His metal work is above and beyond, and one thing he needed was a belt grinder. He decided to make a 3D model of one in CAD and then build it from scratch. The build video goes through his design process in Fusion 360 and then the actual build of this beast of a machine. The motor is 3.5 horsepower which, when paired with a variable frequency drive, can provide all of his belt grinding needs.

[Emiel]’s videos are always high quality, and his design process is easy to follow as well. We’re always envious of his shop as well, and it reminds us a lot of [Eric Strebel] and his famous designs.

Tools, You Can’t Take Them With You

October 10, 2019 by 91 Comments

When I die I hope be buried in the English rural churchyard that has been my responsibility as churchwarden, after a funeral service that has been a celebration of my life. I am neither an Egyptian pharaoh nor a Viking queen though, so my grave will not contain all my tools and equipment to serve me in the afterlife. Instead aside from my mortal remains it will contain only a suitably biodegradable coffin, and my headstone will be a modest one bearing perhaps a technical puzzle to entertain visitors to the churchyard.

My workshop, my bench, and my tools will be the responsibility of my nearest and dearest, and I hope I will have suitably equipped them for the task of their dispersal. But for anyone who has a sizeable collection of gear, have you thought of what would happen if someone else had to clean it all out? What is profession for some and hobby for others, we deal in specialization that might as well be tools of arcane magic to the uninitiated.

Hacked Calipers Make Automated Measurements A Breeze

July 4, 2019 by 22 Comments

Now, digital calipers with wired interfaces to capture the current reading are nothing new. But the good ones are expensive, and really, where’s the fun in plugging a $75 cable into a computer? So when [Max Holliday] was asked to trick out some calipers for automating data capture, he had to get creative.

[Max] found that cheap Harbor Freight digital calipers have the telltale door that covers a serial connector, making them a perfect target for hacking. A little Internet sleuthing revealed the pinout for the connector as well as some details on the serial protocol used by most digital calipers: 24-bit packets is six four-bit words. [Max] used his SAM32, a neat open-source board with both a SAMD51 and an ESP32 that can run CircuitPython. An inverting buffer interfaces the serial lines to the board, which is just the right size to mount on the back of the caliper head. It’s hard to tell how [Max] is triggering readings, but the SAM32 is mounted as a USB device and sends keystrokes directly to a spreadsheet – yes, with the ESP32 it could have been wireless, but his client specifically requested a wired setup. Taking multiple readings is easy now that the user never has to swap calipers for a pen.

Cheap calipers like these are pretty hackable – you can add Bluetooth, turn them into DROs for a milling machine, or even make them talk.
