Does anyone know how to create a sliding type of joint/hinge in Newton? I have a (Newton) forklift which drives around beautifully but also needs to be able to raise and lower the forks to pick things (pallets) up.

PS. Newton is great! I've only beein using it for a little while but so far I am very impressed - well done Newton! if I can get these forks to go up and down like a real forklift then I will be over the moon
