This is a Vertical Slotter Machine designed to run off an overhead belt system. Iam told this is actually a Wheel Boring Machine, and I think it actually is. The original pictures I used as a guide called it a slotting machine.
This model is also offered as part of a larger set.
All models arrive unpainted shipped direct from Shapeways. Most have to be cleaned prior to painting. You can get more information at my website:
