One-Off Cast Iron

I had an incredible talk with Craft Pattern today, about making a custom cast iron machine frame.

They really took the time to talk me through the process and helped me understand the different techniques used.

Isn’t it great when you get to talk to someone who knows what they are talking about?

Have you considered cast iron as a possibility on any of your projects?  I hadn’t until recently, but now a whole new world of possibility has opened up.

In addition to casting, they offer full CNC machining services on the castings, so it sounds like a one-stop-shop.




CNC Gears Made From Baltic Birch

If I have a CNC router and haven’t made wooden gears – isn’t that a crime? -> SVG -> InkScape -> EPS -> VCarve Pro -> WinCNC -> CAMaster CNC Router -> Baltic Birch -> Gears


They run very smoothly.  Next I need to improve the mounting.  I’m thinking either real bearings or HDPE bushings.

The Wonder Of 3D Printing

Here is a little robot the kids and I were working on.

We designed it in Solidworks.

Prepared for printing in the MakerWare software.

8-12-2013 10-21-54 PM.png

Printed it on the MakerBot.  It failed halfway through and we had to re-print some of the parts.


Here is a closeup of the print.


And some pictures of the finished chassis.


We used custom rubber bands for tires. Threads were even printed into some of the parts so 6mm bolts could screw right in.


A new part for an old Bentley restoration

At Sinking Valley Woodworks, we take on odd jobs from time to time.  One of these odd jobs was some car parts for an old Bentley restoration.  Wood was a much more common material in cars in that era.

This particular piece is what goes at the top of the windshield and connects to the roof.  It has curves on all faces, and compound curves on most.  The new part was made out of Ash, carved on a CNC router, and finished by hand.

Below is some before and after pictures.20151002_141251 bentley part
