Impressive servo you've got on that!

So in BW spinners alone, we currently have a:

Vertical Disk
Horizontal Disk
Horizontal Under Cutting Bar
FBS
And a Drum spinner.

Who's making a vertical bar spinner?

I may look into putting a solenoid in a BW. Did some research into trying it out on a FW, but found it wouldn't be very effectve and gave little advantages. Kudos to the Nipper guys for trying though.
I'm just thinking it'll scale down to BW size better.
