Frank thank you for your input, this is the mark 1 mod zero version of my super grinder,the production version has a moulded plastic ergonomic handle, if you look closely at your Bee grinder you will see that my tensioning system is similar only in that both grinders use a torsion spring , my spring tensioner is built using my own spring winding machine, and does not use the Bee plastic tilting tensioner wheel or casting, my design uses solid CNC Machined from billet tracking, platen and drive wheels, it also incorporates 1.5 inch /40mm tooling arms, please note my grinder accepts Wilmont or KMG tooling arms ,my arms will not fit the KMG , shoot me a pm and I will send you one of my bee grinder adjustable tool rests to test drive , Terry
