Building A Boring Head

A Carriage Stop For The Lathe I havent been completely idle on builds like TinyMill. Ive just needed more tools. One thing Ive been wanting for quite some time is a boring head for my mill. And when I was re-designing the x-y stage for TinyMill, I realized that I actually needed one. So Im going to build one, because Im crazy. Ill be following another one of Deans builds. One thing that I considered in my decision to build this was cost. And because I dont just happen to…

Building A Boring Head Part 2

Building A Boring Head   And so it begins.   I cut off a couple 1.25 lengths of the cast iron bar, and faced the ends to make them pretty. The big thing about this cast iron bar is that it isnt round. So although the ends of the bar are flat now, they arent necessarily perpendicular to the length, or even parallel with each other.   I popped one in the 4-jaw chuck, and faced the end again. I now have an end thats flat and straight as long…

An Aside Making Counterbores

TinyMill Part 6 Over the course of designing some more parts for TinyMill, I realized that I needed to counterbore some holes. I could easily fake it with an end mill or drill bit, but one of my design goals was to not have any kludges. I could buy a counterbore, but thats $30 for a set that I might use one of every (not) so often. Or I could buy some drill rod and make my own. Guess which option I chose. Before I start, I need to give…

Making Coasters

Inspiration A while ago I found out about Evil Mad Scientist Labs font coasters. I thought it would be lots of fun to make my own, and so I began scanning for fonts and material. I decided that Times New Roman was too drab, and settled on something more exciting Webdings. I had been putting this project off until I found a roll of cork in the basement, and then I had no excuse. What follows is an attempt at documenting the process of making a font coaster on a…

Quantum ORD Bot

Introducing The Odd-End

Quantum ORD Bot   Ive been printing a lot lately with a couple of extruders. On my ORD bot, I use a MakerBot MK7, and on my cupcake, I use a MakerGear stepper plastruder. And what Ive come to realize is that I dont really like either of them. Or rather, I really like some elements of each, but not really the whole package for either. The MK7 is very compact, and I really like that, especially for a smaller printer like the ORD bot. And the hot-end is uniquely…

Motor Controllers Autopsy And Analysis

What The Hell Has Been Going On Here?

Motor Controllers Autopsy And Analysis I mean really, its been four months. Thats not cool. Which means now I get to try to sum up a whole lot of things in as few words as possible. This should be interesting. ChipiKart I did finish it. See? It even ended up looking somewhat presentable with the Mercedes 300SL body on it. I ended up using 120A Kelly controllers on it, as the hacked jasontrollers just werent cutting it. I regret nothing. Proper controllers are a thing of beauty. With it being…

Playing With Motors Sensors!

  I mentioned before that I had gotten a sensor board from Charles. I had one board, which I intend to mount on TinyBike. However, I also want to put them on chipikart, which has two motors. Clearly, more sensors are needed, so I ordered some boards from my favorite purple board fab. And two weeks later, they arrived! Solder party time! A short time later, sensors! My three boards next to the MIT originalĀ®. Now to print some mounts and then Wait a minute. I dont have motors yet.
