I am making a new ball machine. Could anyone help me with elements to put in it?

I already have two chain lifts, plan to make a rollerball lift, and maybe a big arm lift.

Also, does anyone know of a substitute for tubing that the rollercoaster car can ride on? I am running out of the bendy rods that the tubing goes on, and don't know if i even have enough tubing.

just search knex elements and you'll get a whole lot of good instructables, I think it would be difficult to find an alternative for tubing...

If you just want to make turns, you could use the yellow turns. (from the Extreme guide to Knex Ball Machines)
