Single phase wide drum sander. Max width 560mm, or it can do any width if you undo the outer support arm (it's designed to be used like this if nec.).

Used once (literally one piece of wood to test it out). Haven't ended up doing the work I bought it to do, and don't have room for it to store it in the garage, even on wheels it's just in my way all the time.

Retails at circa £1,800.  Basically a brand new machine.
