Where can I get 40 & 20 tooth gears in UK?

[BazookaJo]

In the process of building my own SW yoke, and am wanting to use the 40 and 20 tooth gear method for the y control as described on Menace's yoke tutorial.

Had good look on the web and I can't find any on UK sites ( >:(typical).

Anyone know where I can get them and what exactly I need (not even sure what actual size they are)?

Many thanks in advance.

Joe.

Have you tried a hobby shop? Check out some of the radio control car gears. There is quite a selection of them out there and you may be able to find the right combo of gears to get the ratio you need.
You should have no problem finding a 20 tooth pinion gear and 40 tooth spur gear.

Yes, I would try an RC Hobby shop first.

Otherwise you could try someplace like this http://www.smallparts.com/products/descriptions/gd.cfm

You could try maplins

If that doesnt work these are the product codes
WC81C - spur gear set
WC78K - gear set

They are made by a manufacturer called mfa comodrills who look like they only sell in packs of ten (under accessories)

If you can't find anyone, Jameco ships international - that's where I got mine. You'll probably get killed on the shipping though. Good luck with the yoke, I am building the same one from the same plans!

I just assembled everything I need to build it, and have started cutting the wood. Keep us posted on your progress, I would like to see how you make out.
