Description

This ball launcher uses the principles of magnetism and conservation of momentum to accelerate ball bearings along the rails and eject the final ball with substantially increased velocity.

Very cool. Please forgive my ignorance, but does adding a second stage increase the velocity over a a single stage gauss gun?
No video because mine is incomplete and my laser cutter is now borked. It is functional though and the first two stages which I did manage to assemble were very promising. The ball that comes out the end bounces off the elastic bands holding my version together with quite a lot of force.

Instructions

This version has 2 sets of rails for operation at any angle. It also features a small magnet at the back to hold the first ball bearing up at those angles.
It's a bit difficult to launch and I failed to cut the third stage but the two stage version is functional and provides significantly improved velocity over the first gauss gun.

You will require 6mm and 12mm x3mm magnets for this version, the magnets are sandwiched between the 3 layers of the bracket, holding them firmly in place without any glue. A small 1mm magnet holds the first ball bearing back.
