One of the weaknesses with the cheaper routers is the basicness of the
parallel guide. I was thinking about finding a way you improve mine
and was sure I would find somebody on the net who would have tackled
this already and posted his design, but no such luck. Any ideas
anyone ? I've got a lathe, etc.

Simplest way is to fit a longer, straight piece on timber to the face of
the parallel fence.
