ask and you shall receive!
the pressure is as much as you want to give....i use a fair amt...atleast 10-15 lbs i figure.
just dragging the 'sink will have you lapping until your toemail's grow up to your nose....
i just try to push the sink THROUGH the table...and i stand, so my arm is about a 45 from my body...mostly i bend at the waist.
push too hard.. and you'll never get that mirror finish perfect....so with that in mind, your best of to give light pressure, like you describe, at the end to polish it up.
