My first wooden gears

What method did you use to cut those out?

@rma002 Everything was done by hand on the bandsaw. I first rough-cut the outer circle, then made inward cuts along the surface of the teeth. In the gullets, I usually just nibbled away with the bandsaw, moving the gear side-to-side approaching the line. Nothing extremely precise, but good enough for a proof of concept!

Wow !!!! did you write this gear program. If so congratulations and 10 out of 10

[yewtewber]

Nope - sorry. I attributed that to Matthias Wandel in the video description section.

Another tip I've just discovered on my own. When using spray adhesive to stick the paper to the wood, just a light spray will keep things well in place, but you can still peel off the paper with little trouble.

Thanks for the tip about the spray glue. Is there any way I can get a hard copy of the gear program on disc ? Cheers Peter

@yewtewber what adhesive did you use? I try to use wood glue, but it's just not accurate enough.. it wobbles around and the layer always gets too thick..

@MrKaddan

I just used a 3M brand general purpose spray adhesive. On my first gear, I really sprayed a thick coat, but after cutting the gear I found the paper difficult to remove. On later gears, I did a light coat. That held the paper in place very well but allowed it to be peeled off after cutting.

The bandsaw does a good rough cut, but on gears for actual use, I smooth the rough edges with a rasp and/or file.

QUICK TIP: Drill your center hole first, then cut the teeth.

Amazing! You should make a jig of some sort to hold the two gears together.
