What should be added to an order for a LEAD 1010 so it could be built as 1000mm x 500mm? The idea is to be able to rebuild the machine as 1000mm x 1000mm using the original parts, when there is space for the larger machine. If I'm correct, I would need to add the following: - (3) of "V-Slot 20x40 Linear Rail" (500mm length) <V-SlotĀ® 20x40 Linear Rail> - (2) of "C-Beam Linear Rail" (500mm length) <C-BeamĀ® Linear Rail> - (2) of "8mm Metric Acme Lead Screw" (540mm length) <8mm Metric Acme Lead Screw>
