Tips For Basic Machining on a Drill Press

It’s safe to say most Hackaday readers would love to have a mill at home, or a nice lathe, but such equipment isn’t always practical for the hobbyist. The expense and amount of room they take up is a hard sell unless you’re building things on them regularly, so we’re often forced to improvise. In his latest video, [Eric Strebel] gives some practical advice on using a standard drill press to perform tasks you would normally need a mill or lathe for; and while his tips probably won’t come as a surprise to the old-hands out there, they might just help some of the newer players get the most out of what they have access to.

[Eric] explains the concept of the cross slide vice, which is the piece of equipment that makes machining on a drill press possible. Essentially it’s a standard vice, but with screws that allow you to move the clamped piece in the X and Y dimensions under the drill which can already move in the Z dimension. For those counting along at home, that puts us up to the full three dimensions; in other words, you can not only make cuts of varying depths, but move the cut along the surface of the work piece in any direction.

You can even turn down a (small) piece of round stock by placing it in the chuck of the drill press, and putting a good chisel in the cross slide vice. The chisel can then be moved up against the spinning piece to make your cuts. We don’t suggest doing anything too heavy, but if you need to turn down something soft like a piece of plastic or wood to a certain diameter, it can do in a pinch.

[Eric Strebel] is quickly becoming a favorite around these parts. His well-produced videos show viewers the practical side of product design and in-house manufacturing. We recently covered his video on doing small-scale production, and there’s plenty more invaluable info to be had browsing back through his older videos.

The quest to do machining without actually having a machine shop is certainly not new to Hackaday. There have been many different approaches to solving the issue, but picking up a decent drill press and cross slide is a first step down the rabbit hole for most people.

Drill the Wet Side Wet and the Dry Side Dry

Working mostly in metal as he does, [Tuomas Soikkeli] has invested in some nice tools. So when his sweet magnetic-base drill was in need of a new home, he built this two-in-one drilling station to maximize shop space and add some versatility to boot.

For the non-metalworkers out there, a mag-base drill is basically a portable drill press where the base is replaced with a strong electromagnet like the one shown here. They’re often used in the construction trades to drill holes in steel beams or columns, and often include nice features like a built-in coolant system.

[Tuomas] effectively turned his mag-base drill into a very beefy drill press by mounting it to a disused miter saw stand. A thick piece of plate steel forms the base, and with holes and drain channels machined into it, used coolant can be captured in a drain pan below for reuse. A second base for a benchtop drill press means he’s got a dry drilling station too, and the original support arms on the miter stand are ready for drilling long stock. The drawer below the dry side is a nice touch too.

There’s a lot to learn about fabrication from [Tuomas]’ video and the others on his channel, which is well worth checking out. And if you want to convert your drill press into a mag-base drill, why not check out this microwave oven transformer to electromagnetic crane project for inspiration?

BeamCNC: Computer-Controlled Construction System Mill

Need to make something quick and dirty out of wooden beams, and want to use elements you know will work together? BeamCNC is a mobile assembly of stepper-controlled rollers and a router that sucks a 2×2 through it and drills the holes in pre-programmed intervals. Currently being developed as part of an Indiegogo campaign currently in preview, its creator [Vladislav Lunachev] has declared it open source hardware. It’s essentially a CNC mill that makes Grid Beam, a classic DIY building set that resembles Meccano, Erector, and other classic sets, only made full-scale for larger projects. While BeamCNC is not affiliated with Grid Beam, it takes the same general idea and automates it.

Drill Press to Mill Conversion

Every time we look at the little short Z axis of our CNC mill, we think about converting a drill press to a mill. In theory, it seems like it ought to be easy, but we never quite get around to it. [AvE] did get around to it and made his usual entertaining video about it that you can see below. If you haven’t seen any of [AvE’s] videos before, be warned: there is a little colorful language in a spot or two.

This isn’t a CNC mill, by the way, although we suspect you could convert it. Essentially, he adds a spindle and an XY table to a Ryobi drill press. It sounds simple, but getting everything to work did take a few tricks, including a blow torch.

Actually, turns out the blow torch didn’t really do it, but we won’t spoil the final resolution to the problem. Once it was resolved, though, he did manage to do some actual milling, accompanied by some music we wouldn’t associate with [AvE].

Although billed as a “poor man’s” build, the XY table alone was about $200. So add in the cost of the drill press, the spindle, and the mill and this is still a fair chunk of cash. We’d love to see it compared to a Harbor Freight milling vise. We suspect the Harbor Freight vise might not be as good, but is the difference worth the $130 difference in price?

We’ve seen this kind of conversion done before without the colorful language. If you do this conversion and want some practice, why not build a magnetic carabiner?

Make a PVC Drill Press

There are two types of people in this world: people who think that PVC is only suitable for plumbing, and people who don’t even know that you can use PVC to carry water. Instructables user [amjohnny] is clearly of the latter school. His PVC Dremel drill press is a bit of an oldie, but it’s still a testament to the pipefitter’s art. And you can watch it in action in the video embedded below.

Things we particularly like about this build include the PVC parallelogram movement, springs around tubes to push the Dremel head back up, and the clever use of a T-fitting and screw plug to hold the press in its lowest position. We wonder how one could add a depth stop to this thing. No matter, we love watching it work.

Anyway, this is just one hack of many that emphasizes the importance of a drill press in basically anyone’s life, as well as the ease of DIY’ing into one. If you’re in the PVC-haters camp, but have some scrap wood and drawer slides or plastic offcuts lying around, you have the makings of a rudimentary press — a welcome tool in the shop.

Building an IoT Drill Press for Reasons Unknown

He’s a little cagey about the reasons, but [Ivan Miranda] plans to put a drill press on the internet. What could go wrong with that?

We’ll take [Ivan] at his word that there’s a method to this madness and just take a look at the build itself, in the hopes that it will inspire someone to turn their lowly drill press into a sorta-kinda 2-axis milling machine. [Ivan] makes extensive use of his 3D printer to fabricate the X-axis slide that bolts to the stock drill press table. And before anyone points out the obvious, [Ivan] already acknowledges that the slide is way too flimsy to hold up to much serious drilling, especially considering the huge mechanical advantage of the gearing he used to replace the quill handle for a powered Z-axis. The motor switch was also replaced with a solid state relay. The steppers, relay, and limit switches are all fed into a Teensy that talks to an ESP8266, which will presumably host a web interface to put this thing online.

The connected aspects of the drill press become a little more clear after the break.

Likely Everything You Need To Know Before Adopting A Drill Press

Oh sure, the thought of owning a happy whirring drill press of your very own is exciting, but have you really thought about it? It’s a big responsibility to welcome any tool into the home, even seemingly simple ones like a drill press. Lubricants, spindle runout, chuck mounts, tramming, and more [Quinn Dunki], of no small fame, helps us understand what it needs for happy intergration into its new workshop.

[Quin] covers her own drill press adventure from the first moments it was borne into her garage from the back of a truck to its final installation. She chose one of the affordable models from Grizzly, a Washington based company that does minimal cursory quality control on import machinery before passing on the cost to the consumer.

The first step after inspection and unpacking was to remove all the mysterious lubricants and protectants from the mill and replace them with quality alternatives. After the press is set-up she covers some problems that may be experience and their workarounds. For example, the Morse taper on the chuck had a few rough spots resulting in an incomplete fit. The chuck would work itself loose during heavier drilling operations. She works through the discovery and repair of this defect.

Full of useful tips like tramming the drill press and recommended maintenance, this is one of the best guides on this workshop staple that we’ve read.
