Machining a Titanium & Walnut Ring

While walnut is a farly straight-grained hardwood that is easy to work with, titanium is one of the more difficult materials to machine, especially in the home shop. This article isn't to be considered a how-to, rather a chronicle of my experience in creating a wedding band combining the two materials.

2D drawing with RepRap

Testing a pen on the RepRap

I'm sharing my solution for generating GCode to draw 2D on my 3D printer. I had been looking for a method to use my RepRap to draw on paper, much like a plotter, but was not having much success looking for a good method of turning .dxf files from LibreCAD or similar CAD software into .gcode that the printer would understand. I was able to generate some flavor of GCode using PyCAM, but it wasn't the particular flavor that the Marlin firmware on the RepRap could interpret.

AC Motor Cooling Fan

While repairing the AC motor on my lathe, I managed to destroy the dry-rotted plastic cooling fan mounted to the shaft. Since a replacement is somewhat difficult to source, I thought I would try to make one myself. The motor and its components are oddly-sized, so I wrote the OpenSCAD module to be fairly parametric so that it may be useful in more common applications.

For those curious, my lathe is a 3-in-1 Shopmaster El Dorado made in 2000. Unfortunately, mine wasn't built with the Quadralift option that allows the operator to easily raise and lower the milling head.

Using make with OpenSCAD

It is often useful when working with OpenSCAD to generate .stl and .gcode files in an automated fashion. For this, I created a Makefile for use with GNU Make for generic OpenSCAD modeling.


Customizable 3D-Printable Comb

This 3d printable comb, generated by OpenSCAD, has configurable dimensions and can be made compatible with nearly all hair types. As I've configured it, it fits conveniently in my wallet next to my credit/debit cards. It's a fairly simple print and I found it useful when dialing in Skeinforge (or any other slicer) settings on my RepRap Prusa.

Stainless Steel Click Pen

I made this simple click pen out of stainless steel hex stock on my metal lathe. It uses a standard 3-piece plastic mechanism and uses a Fisher Space Pen cartridge.

Simple Pizza Dough

This is a simple pizza dough recipe that can be mixed up in a few minutes by hand or with a stand mixer, tossed within a few hours, and baked in minutes into a delicious pizza.

Buttermilk Biscuits

Buttermilk biscuits are great served alone, with butter or preserves, as breakfast sandwiches, or under sausage and sawmill gravy.
