CNC Mod Pack Hopes To Make Something Useful From A Cheap Machine Tool

Posted on by

It is probable that many of us have noticed a variety of very cheap CNC mills in the pages of Chinese tech websites and been sorely tempted. On paper or as pixels on your screen they look great, but certainly with the more inexpensive models there soon emerges a gap between the promise and the reality.

[Brandon Piner] hopes to address this problem, with his CNC Mod Pack, a series of upgrades to a cheap mill designed to make it into a much more useful tool. In particular he’s created a revised 3D-printed tool holder and a set of end …read more

Card Reader Lockout Keeps Unauthorized Tool Users at Bay

Posted on by

It’s a problem common to every hackerspace, university machine shop, or even the home shops of parents with serious control issues: how do you make sure that only trained personnel are running the machines? There are all kinds of ways to tackle the problem, but why not throw a little tech at it with something like this magnetic card-reader machine lockout?

[OnyxEpoch] does not reveal which of the above categories he falls into, if any, but we’ll go out on a limb and guess that it’s a hackerspace because it would work really well in such an environment. Built into …read more

Bolt-Together Belt Grinder for the No-Weld Shop

Posted on by

Belt grinding offers a lot of advantages for the metalworker, and since belt grinders are pretty simple machines, shop-built tools are not an uncommon project. A bolt-together belt grinder makes this tool even more accessible to the home gamer.

With no access to a welder but with a basic milling machine and an ample scrap bin at his disposal,  [IJustLikeMakingThings] had to get creative and modify some of the welding-required belt grinder designs he found online to be bolt-up builds.  The key to a cool running belt grinder is for the belt to be as long as possible, and the …read more

A Fix for the Lightweight Machine Tool Shakes

Posted on by

No matter what material you work with, the general rule is that with machine tools, the heavier, the better. Some people can’t afford or don’t want big tools, though, even with their natural tendency to reduce vibrations. That doesn’t mean something can’t be done to help the little tools, like reducing vibration in a contractor-grade table saw.

This one might seem a little outside the usual confines of the hackosphere, but nobody can doubt [Matthias Wandel]’s hacker chops and he really shows off his problem-solving skills with this one. His well-worn contractor-style table saw has had more than a few …read more

Go Go Camera Slider

Posted on by

Are your arms getting tired from pushing your camera back and forth across your camera slider? That must be the case with [Max Maker], which led him to convert his manual slider into a motorized one.

The electronics are minimal — an Arduino Micro, a few toggle switches, A4988 Stepper Driver, 12V battery pack, and the ever popular NEMA 17 stepper motor. If you’re wondering why we said ‘switches’ instead of ‘switch’, it’s because 4 of the switches are used to select a time frame. The time frame being how long it takes for the slider to move from one …read more

Restoring a Strange Milling Machine from Craigslist

Posted on by

[diyVT] found a real white elephant in this milling machine from Craigslist. It cost him only $200, cheap for a small mill, so it was worth the gamble. We’re not sure what to call this — it’s not exactly a gantry mill, not a horizontal mill, and definitely not a knee mill. The tag says V-Mill, made by either Pierce West or Tree Tool and Die Works, depending on which ID plate you read. The Tree has a three-phase motor, but it came with a phase converter, so it should be good to run on single phase 220 volt household …read more

Bulking up a Lightweight Lathe with a Concrete Cart

Posted on by

When it comes to machine tools, a good rule of thumb is that heavier is better. A big South Bend lathe or Bridgeport mill might tip the scales at ludicrous weight, but all that mass goes to damping vibration and improving performance. So you’d figure a lathe made of soda cans could use all the help is could get; this cast concrete machine cart ought to fit the bill nicely

Perhaps you’ve caught our recent coverage of [Makercise]’s long and detailed vlog of his Gingery lathe build. If not, you might want to watch the 5-minute condensed video of the …read more

Machine Tool Build is Anything But Boring

Posted on by

“So just like every other great story in history, ours is going to start at the lathe.” Truer words were never spoken, and thus begins the saga of turning a bar of chrome-moly steel into a shop-built boring head.

You may have a few questions regarding [ThisOldTony]’s effort. First, unless you’re familiar with machine tooling, you may wonder what exactly a boring head is. The video below makes it plain, but the short answer is that it’s a tool to make holes. A boring head spins a boring bar with a cutting tool, and the head can be offset to spin …read more
