Hi, this is my first post, I hope that someone will be able to help me :)

I am trying to join two motors normally found in alarm clocks, I wish to join them with a metal cylinder with about a cm bigger diameter than antenna's found on radios. How would I go about joining each motor to each end, I cannot get welding and don't know if it would apply even to such small electronics, soldering seems impossible as it won't join, any advice is much appreciated, thanks

P.S The end product would look like the base of a RC car, but without the wheels thanks.
