A Scratch-Built Drill Press Vise From Scrap

August 29, 2018 by Dan Maloney 12 Comments

Never underestimate the importance of fixturing when you’re machining parts. No matter what the material, firmly locking it down is the key to good results, and may be the difference between a pleasant afternoon in the shop and a day in the Emergency Room. Flying parts and shattered tooling are no joke, but a lot of times quality commercial solutions are expensive and, well, commercial. So this scratch-built drill press vise is something the thrifty metalworker may want to consider.

To be sure, [Ollari’s] vise, made as it is almost completely from scrap angle iron, is no substitute for a vise made from precision ground castings. But it’s clear that he has taken great care to keep everything as square and true as possible, and we give him full marks for maximizing his materials. And his tools — nothing more complicated than a MIG welder is used, and most of the fabrication is accomplished with simple hand tools. We like the way he built up sturdy profiles by welding strap stock across the legs of the angle iron used for the jaws, to give them a strong triangular cross-section to handle the clamping force. And using the knurled end of an old socket wrench as the handle was inspired; we’ll certainly be filing that idea away for a rainy day in the shop. Although we might use Acme rather than plain threaded rod.

We always enjoy seeing someone fabricate their own tools, and this one reminds us a bit of the full-size bench vise built up from layers of welded steel we featured a while back. It even looks a little like this 3D-printed vise, too.

Wireless Charger Gives A Glimpse Into Industrial Design Process

May 26, 2018 by Dan Maloney 15 Comments

Almost every product on the market has been through the hands of an industrial designer at some point in its development. From the phone in your pocket to the car in your driveway or the vacuum in your closet, the way things look and work is the result of a careful design process. Taking a look inside that process, like with this wireless phone charger concept, is fascinating and can yield really valuable design insights.

We’ve featured lots of [Eric Strebel]’s work before, mainly for the great fabrication tips and tricks he offers, like how to get a fine painted finish or the many uses of Bondo. But this time around, he walks us through a condensed version of his design process for a wireless phone charger and stand. His client had specific requirements, like being able to have the phone held up in landscape or portrait mode, so he started with pen and paper and sketched some ideas. A swiveling cylinder seemed to fit the bill, and after a quick mockup in PVC pipe, he started work on a full-size prototype in urethane foam. There are some great fabrication tips in the video below, mainly centered on dealing with not owning a lathe.

The thing for us with all of [Eric]’s videos, but especially this one, is seeing the design process laid out, from beginning to (almost) the end. He sure makes industrial design look like a cool gig, one that would appeal to the Jacks- and Jills-of-all-trades who hang out around here.

Tips For Basic Machining On A Drill Press

November 19, 2017 by Tom Nardi 76 Comments

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

November 18, 2017 by Dan Maloney 4 Comments

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

September 27, 2017 by John Baichtal 8 Comments

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

July 4, 2017 by Al Williams 39 Comments

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

March 31, 2017 by Elliot Williams 32 Comments

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.
