3.4 Location of distance stop
The drive wheel should NEVER come in contact with the sanding belt. The distance
stop is a safety precaution so that this can be avoided. For each pip dimension the
distance stop must be adjusted, in order to avoid that the propulsion jig tilts down and
comes in contact with the sanding belt. See the explanation in diagram 3.4. Here, the
distance stop(1) is moved almost down to the plate(2). The distance stop between (1)
and (2) must be 2-5 mm/0.1-0.2 inch - never less than 2 mm/0.1 inch.
