Hi I am making a small wobbler and want to use a Meccano spring drive belt on it.

I have just ordered the belt and it is 1.5mm dia, but I do not know what V to cut for it.

The plastic round belts seem recommend 35 – 40 deg V. Does any one know what it should be for a metal belt or have one they could measure?

Thanks

Adrian

I've dug out and dusted off a small Meccano pulley (it says so on the side) for you to see their profile.

Added. The dimensions are 4.75mm across the flange faces (hub is a bit wider) and 15.33mm outside diameter.

Meccano Index drawings give the angle of the pulleys as 64 degrees.

Hope this helps.
