I've re-designed my knife grinder to make it cheaper to manufacture and easier to assemble in kit form. It offers a sliding tool arm so you can use belts of different lengths or replace the platen with a contact wheel.
I have removed the need for flange bearings and instead mount the motor and drive pulley directly to the grinder. The savings from doing away with the flange bearings and belt pulleys and the work involved in attaching them to the grinder means the money saved can be used for a more convient variable speed motor. It also gives the grinder a smaller foot print so saves space. It can be mounted on a pedestal.
It will be made out of thick steel sections for rigidity and strength. The construction will be all straight foreward nut and bolts so only need a couple of spanners to assemble it.
