I have a new to me Minimax CU300. I can't get the shaper spindle to raise. Here is what I have tried: the locking knob is backed off. I have tried turning it counter clock wise, per manual and schematic. When I turn the spindle it spins freely topside or using the belt, below.
It feels like it is locked or seized. When I try to turn it I can move the handwheel maybe half a turn, with effort. The shaft going to the 90 degree box is free, feels fine and I can see play in it. When it reaches the point when it won't turn any further it feels solid, not spongy. I have tapped the spindle, gently and sprayed some PT Blaster in there to let it sit overnight. Anyone had a problem like this?
Any suggestions? Am I missing something really simple on this machine?
