Reeds 'n Stuff English Horn Pre Gouger
This Reeds 'n Stuff pre gouger not only planes the cane with a flat blade but also gouges it out to about .80mm in the middle and .65mm on the sides with a circular blade. The bed fits cane up to 12.5mm diameter. This amount of pre gouging saves the blade of your gouging machine and also speeds up the gouging process. It only takes a couple of seconds to send a piece of cane through this pre gouger.
Another option is available by Reeds 'n Stuff for the pre gouging step.
