Can you use a dc series motor as a prime mover for a dc generator. if not why?
A DC series motor would be ill-suited to this application.
There would be times when the generator would be only lightly loaded and would present only a small mechanical load to the motor. Under these conditions the current in the field winding of the motor would become smaller and it would turn faster to generate the counter EMF necessary to balance its supply voltage. This could result in damage to both the motor and the generator.

Straight cuts: table saw, circular saw, jig saw, pretty standard just remember to use a higher teeth count on the blades
Inside cutouts: jig and router
When working with MDF make sure you use respiratory and eye protection as the dust contains formaldehyde.
Why is it necessary that the tool be clamped tightly in the tool post?
If the cutting tool is not tightly clamped in the tool post it could move when a cut is taken.
This can result in the tool penetrating the workpiece as the cut progresses causing an undersized workpiece. It can also eventually bite into the workpiece and possibly cause damage to the workpiece, the lathe, the cutting tool and even injury to the machinist and others in close proximity.
