pic: Need an EDU Beval Gear

[Joe Johnson]

Berg sells miter gears that can be made to work with the EDU kit.

It will not be pretty but it can be done.

I recommend a 1 to 1 ratio with a relatively small diameter to keep "tilt" from disengaging your teeth ( like the pair M72N-1A for example).

This gear set is aluminum and has a 1/8 inch bore. You will have to make the hole square. To do that, I recommend the following broach from McMaster.com 3156A11 -- the problem is that it costs a bit more than I like -- but I have used it and they are beautiful for making EDU compatible square holes in aluminum parts).

Also, the pitch of these gears is a bit danty (72DP -- that means . You will likely have issues trying to get these gears to stay engaged reliably -- the teeth are only a little more than a half mm tall!)

To be honest, I suppose that for the most part, you could modify something from another toy set (Lego maybe) and have better success.

Good luck just the same.
