I have a Jet WSS-3-3 shaper that I picked up fairly cheap.It has one 1" spindle an I would like to add a 1/2" and possibly a collet spindle.Does anyone know the size that may fit this unit?Maybe another brand that will interchange because the unit is obsolete. It needed a spindle bearing and now it runs great.It's a 5HP 3 phase unit.I have a small wood boat restoration shop and the shaper comes in handy.
