And i guess I'm a little confused how I'd use a torque wrench
You turn the screw with a torque wrench. I am lucky in that I have one that has dial indication which when observed will show
the torque that was required ie; just to start turning the screw, how much torque was applied to continue moving the axis.
I use it to adjust bearing preload ie; it indicates the difference in torque required to just move the axis , so if i adjust the preload
to remove / reduce backlash I know how much of available motor torque was used since you want you want minimize it.
If you were to put say a 50 # weight on the table and see what setting the torque wrench click's at you have the torque required
to lift that wieght which will include all the friction factors or binding in the table which is better than tryng to add assumptions
if calculated. Try the table when all the way down, at 45 deg angle ( probably half travel ) and just about at the full travel.
You could also use the torque wrench by reducing it's setting to see where the motor will not stall / skip.
All this can be done quickly,but, i will add that you should have confidence in the wrench settings.
SAFETY:
You wouldn't try to measure the torque of you car engine this way to see what force at the handle was required so common sense
is required if you have really high torque motors on your machine.
Hey, Hey I still remmeber our Hillman Minx car
with column mounted 4 speed reverse pattern
, that had a hand cranck which you could use until you could afford a new battery.
Crank handle could rip your arm off in a heart beat if not done correctly.
