* Adjustable table * Spring belt tensioner * Dust collection * Motor V Belt tensioner * Adjustable belt tracking This has been built and works very well with 1 HP 4 pole 1400rpm motor. Careful attention needs to be given to shaft position and relative angles to ensure good belt tracking. Drums are made from 90mm PVC down pipe with mdf core. It is advised that several staggered layers of gaffa tape be used to give the drums a slightly raised profile in the centre. This helps with belt tracking.
