Remember, the DVR has a power switch *AND* an on/off button. By pushing the OFF button, you engage the dynamic braking and the
lathe slows down immediately. By throwing the POWER SWITCH or removing the power entirely (unplug it), it will continue to spin
under power for a few seconds before shutting down. When cutting the power at 3500rpms, the lathe continues for about 1 second
before shutting down. At 500, its more like 4 seconds. Obviously, there are some capacitors in the unit which are draining.

So a switch at the tailstock end is better than nothing, but it will not provide INSTANT shut down.

You imply that its not much good to have a switch on the tailstock end. Are
you saying that when you shut off with a switch at the tailstock that it
keeps going more than it would if shut down at the headstock controls, i.e.
a braking function is not activated or something similar? Otherwise, if the
lathe slows down at the same rate, the tailstock switch would seem to be
helpful.



Well, sort of. I generally wire up power switches on BOTH ends of all my


lathes for safety. But its not much good on the DVR. When


you cut power to the lathe, it still spins (under power) for a few seconds


before it finally shuts off. Its a function of the


motor design itself, NOT the fact that its direct drive.
