Thank you guys for all of the replies and the reason being for a custom gear is to try and keep the box as small as possible. I am going to toy around with the CAD and see if I cant get the small bevel gears to work from mcmaster.

I think this is a situation where the tradeoff between a easier to get, less optimal COTS part and a custom, higher performance part pretty definitively leans to one side.

You should check out SDP-SI, they have a better selection for gears. http://www.sdp-si.com/eStore/CoverPg/Gears.htm

QTC is also in the same corporate family: http://www.qtcgears.com/RFQ/BevelGears.htm. You'll have better luck getting appropriately-sized bevel gears from them, than from most other suppliers. Call them to discuss, and to get a quote, and summarize the interaction here.

Casting aluminum gears...

Another option and quite possibly faster and safer, have Shapeways print the gears:

I vote QTC. Rush Gears has a minimum order on the level of $1500 regardless of number. The gears from QTC are of pretty good quality even at the lowest quality they offer for metal gears, and you can buy ground gears if you need to. They have a very wide selection too.
It's very easy to modify the bevel gears if you sue a machinable collet to hold them; I have been shortening the hubs and widening the bores slightly for a project.
