New Lego GBC Workshop Module - Worm Mill

Today I'm presenting the newest module in my "workshop" series.  The Worm Mill (WM02).  This module uses a compact double vertical sweeper to lift the balls from the input area to the output ramp.  The drive unit is connected to the module with a pivot point at the rear so that it won't "snap or pop" if balls get caught under the lifting arms while it's in operation.

The throughput of this module is what I would call "very high" which is common for most vertical sweepers.  It's powered by a lego Power Functions medium motor because it has the anti-studs on the bottom which allows it to connect to the system built drive unit / worm gearbox.  A Powered Up medium motor should work as well since it also has anti-studs.

The gear train is built using the system gearbox, which contains a 2L worm and 24T gear.  You can rig it up for shared power between duplicate modules, but I have not included instructions for that.  There is a bit of trial and error into getting the output to work with the motor removed.  The motor in the regular build is actually part of the output ramp, guiding the balls out.

Free instructions have been added to the Lego GBC Instructions page.
