Zen and the Art of Foam Core

Some of our pastimes are so deeply meditative that we lose ourselves for hours. Our hands seem to perform every step, and sequence like a pianist might recite her favorite song. If [Eric Strebel]’s voice and videos are any indications, working with foam core can have that effect.

Foam core is a staple of art stores, hobby stores, and office supply stores. It comes in different colors, but the universal trait is a sheet of foam sandwiched between a couple of layers of paper. This composition makes a versatile material which [Eric] demonstrates well in his advanced tutorial making a compound surface and later on a speaker mockup.

After the break, you can catch a couple of beginner tutorials which explain the differences between a slapdash foam core model, and one which will draw appreciation. Proper tools and thoughtful planning might be the biggest takeaways from the first two videos unless you count the Zen narration. The advanced videos, linked above, show some ingenious ways to use foam core like offset scoring, adjustable super-structures, and paper transfers.

Each video is less than ten minutes long, so if you just started your coffee break, you can complete a video right now. Or look at another 2D material turned into amazingness with a papercraft strandbeest, then step up your game with another look at vinyl cutters.

How To Have an Above Average Time With a Cheap Horizontal Bandsaw

[Quinn Dunki] has brought yet another wayward import tool into her garage. This one, all covered in cosmoline and radiating formaldehyde fumes, is a horizontal bandsaw.

Now, many of us have all have some experience with this particular model of horizontal saw. It waits for us at our work’s machine shop, daring us to rely on it during crunch time. It lingers in the corner of our hackerspace’s metalworking area, permanently stuck in the vertical position; at least until someone finally removes that stripped screw. Either that or it’s been cannibalized for its motor, the castings moldering in a corner of the boneyard.

This article follows on the heels of [Quinn]’s other work, a treatise on the calibration of a drill press, and it outlines all the steps one has to take to bring one of these misunderstood tools into consistent and reliable operation. It starts with cultivating a healthy distrust of the factory’s assurances that this device is, “calibrated,” and needs, “no further attention.” It is not, and it does. Guides have to be percussively maintained out of the blade’s way. Screws have to be loosened and adjusted. It takes some effort to get the machine running right and compromises will have to be made.

In the end though, with a high quality blade on, the machine performs quite well. Producing clean and quality cuts in a variety of materials. A welcome addition to the shop.

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.
