Default Living better through CNC

Making wooden gears has always been a hassle for me. It involved transferring the pattern to my stock, drilling the shaft hole on the drill press, and tedious cutting on the scroll saw. Invariably, I spent a lot of time sanding the gear, after cutting, to clean up and correct errors caused by less than perfect saw work. It would require a minimum of 30 minutes to produce something like this 17-tooth ratchet gear.

Today, I embraced the new technology to make my gear. I designed it with V Carve Pro by drawing one gear tooth, and then using the circular array tool to generate the other 16 teeth, followed by placing a 1/4Ē shaft hole dead center.

I cut out the ratchet gear with a single tool path, and production of the entire gear took ó wait for it ó 52 seconds. Less than one minute to cut the gear and drill the hole! Plus, every tooth is perfect, and the hole is dead center.

Life is definitely better.

And for someone like me ,that would take days to get right . Although a cnc is not a replacement for all your tools, it certainly has its place .
Can’t wait to get one

I donít always insulate , but when I do .
Ok ,I never insulate

Oliver, It took over two weeks to make my gear (22-1/2" Diameter). Makes me jealous. A perfect application for cnc routing. Nice job!

That's a beautiful gear. Is it part of a large mechanism?

You cannot really make EXACTLY that out of WOOD with a CNC router unless you use plywood or or some composite material or plastic or metal.

For precision gears CNC waterjet or CNC laser cutter or CNC Plasma (for metals only) would be better than a CNC router.

Oliver, I think you should have been using a bandsaw, not a scroll saw.

Gary's gear wheel done manually had all the wood grain in the correct directions,

If one just cut it from a sheet of wood by CNC router, some spokes for e.g. will be weaker because of wrong wood grain orientation.
So Plywood or other materials will be needed and so the gear will NOT be exactly the same.
