A new switch may help. Unless ya have a short elsewhere.

I would bet that beeg is correct; you most likely need a new switch. But, this is a very uninformed statement. The information provided tells us very little except that you have worked on the switch.
What model Shopsmith do you have. Does this unit switch both the hot and the neutral side.
UNPLUG the Shopsmith.
If you have (or can acquire) a multimeter, measure the resistance between the two flat prongs on the Shopsmith power cord. Alternately, switch the Mark V switch on and off while observing the multimeter resistance reading. It should change from an open (infinity) to a short (very low resistance). If it does not change consistent with the switch action - beeg is correct. You need a switch.

Aha! They go back in the same position as they were when taken apart!
You need to figure out how it is supposed to work, then assemble. This is far more easier to say than do!
Perhaps getting a new switch is a more reasonable(less time consuming/less frustrating) option at this point.
Make sure you understand how to attach the wires before 'turning it on'!
