This sale is for a hollow grind attachment, It is shown on my my belt grinder design, but it can be modified to fit others. Please contact me if you need custom mounting brackets for your specific grinder. Just to clarify, this sale does not include the contact wheel or other parts of the machine. Just the hollow grind fixture. If you are mechanically inclined enough to grind blades, you know what you are looking at. Others, need not reply
