There are two setscrews in the Jigsaw Guide Stop, but they don't seem to lead anywhere. They
cannot come in contact with the rail, as a) they are two far away and b) there is a piece of plastic
between them and where the rail goes.
Yea I wish they will upgrade them the same way they make the ones on the circular saw so they can be quickly adjusted between all my guides. Took me a while to find them and I was wondering why the guide was so sloppy. Router uses the same thing.
