How To Have An Above Average Time With A Cheap Horizontal Bandsaw

October 2, 2016 by Gerrit Coetzee 27 Comments

[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.

Multimeters Without A Country: Fluke’s Broad Trademark Bans Yellow Multimeter Imports

March 19, 2014 by Mike Szczys 249 Comments

Check out this SparkFun Digital Multimeter. Does it make your blood boil to see them ripping off Fluke by using the color yellow? From SparkFun’s side of the story that’s exactly what’s happened here. They have a shipment of 2000 of these things stuck in customs. The trademark being infringed upon can be found in their article. Fluke owns the trademark on multimeters with a dark face and yellow border. Great. This seems like a wonderful idea, right up there with Apple owning tablets that are shaped like a piece of paper.

Okay, so if you’re not crying big fat tears for Fluke being taken advantage of in this way let’s talk about more immediate issues than fixing trademark, patent, copyright, and all of the other screw-the-little-guy type of laws (not that SparkFun is necessarily the little guy but you know what we mean). The DMMs sitting in a warehouse are costing SparkFun $150 per day. We believe they have no option of choosing a warehouse with a lower cost as we must be talking a pallet or two, right? The only two options they do have are shipping them back to China where they were manufactured, or having them destroyed. The former will cost more in re-import tariffs than the cost of the product, and the latter comes with a $150/hour disposal fee and no metric on which to judge how long it would actually take. We hate seeing this kind of waste, but sure enough 2000 DMMs are headed for the shredder in a couple of days.

We know you already have your flaming sword in hand, but simmer down for just a second. Fluke makes great products, ask anyone. And companies the world over defend their trademarks. Hopefully there will soon be a positive response from Fluke on this one. If you would like to politely encourage them to do the right thing we found Fluke’s Facebook page URL in the SparkFun comments thread. Both are worth browsing.

Advanced Beer Carrier, Or How To Get Beer Onto A Plane

[Badmonky] was facing a life crisis. How could he enjoy the hard-to-find German beers from his homeland while living in Princeton, New Jersey? Sure, you can find many good imports if you try, but that may come at a hefty price. Plus, the lesser known beers are completely unavailable in the States. Of course the solution is to import them himself after each trip home. He just needed a way to get as much beer on a plane as he possibly could.

We’d have no problem walking down the aisle with a couple of cases of cold ones, but let’s be honest here. Security won’t even let you on the plane with a bottle of water these days much less a case of tallboys. [Badmonky] hacked together this custom carrier so that it could be checked as luggage while protecting the frothy goodness. Two limiting factors to consider are size and weight. He started with the latter, calculating that 24 bottles would remain under his 50 pound limit. From there he selected a sports bag and picked up sheets of foam which were perforated using a hole saw. Alas the size constraint forced him to leave three of the (now empty?) vessels behind.

The bottles ride upside down and made the international voyage without incident. In retrospect he would have picked a roller-bag as this thing is hard on your shoulder after a trip through the airport and the public transit ride home.

The real question in our mind: why didn’t he check a keg?
