Mounting base and hardware to mount the Simple Hollowing System on a Shopsmith Lathe. This is not the entire system, only the mounting hardware.
If you purchase the entire system for a Shopsmith lathe (here), you do not need to purchase this mounting hardware as it will come with the system.
If you already have a Simple Hollowing System and want to move it to a Shopsmith lathe, this is the mounting hardware you would need to do that.
