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.

Making a Wooden Shield

We made a wooden shield out of 3/4″ hardwood plywood.  To get the perimeter, we bent an aluminum bar into the shape of one side, and then used it to trace both sides, making it symmetrical.

We softened a section of 4″ PVC pipe and flattened one side.  After plenty of sanding the endges, we screwed it to the back of the shield with 3/4″ screws.

We cut the handle out of a section of 2×4 on the bandsaw, routed, and sanded it smooth.  Here are the pictures!  All done but a coat of gold or silver paint.

(Ezra) making a wooden box

Ezra brought me a piece of plywood today with pencil marks drawn all over it.  That is where he wanted it cut.  So I ripped it on the table saw and cross cut it on the compound mitre saw…

I gave him a little help laying this out, showed him how to clamp it, and then he went to town drilling 1/16″ holes and pounding finishing nails into it.

Only 2 breaks in the drill-bit, which isn’t bad for such a small bit and a 7 year old.

It turned out nice!  We’ll put a lid and hinges on it soon.
