We have hit a bit of a set back on our portable CNC Tube Notcher product. We thought we were go to start manufacturing but our electrical certification path needs a restart. As of now we don't have any units available for sale with 5 on deck waiting for an electrical inspection report. If you have any questions about tube notching please comment or reach out. Our software ADS should work with other CNC tube notchers as well as custom built units which should make tube frame projects much more efficient compared with whole saws and grinders.
