Where to buy Type C sprocket?

[Justin Stiltner]

I dont have a source for double hub sprockets, however playing off what Veselin said, and it seems this would be more cost effective, buy a normal hubbed sprocket, then make another hub for the other side and weld it on using a shaft to center them up. If you have never cut the hub off most sprockets before they are only welded on the very outside of the hub, thus your sprocket would be pretty much what you would get from the factory. Just curious but what kind of application is this going into, as there may be another way of doing it without custom parts.
