Now what I think would be cool would be a nice little hinged adapter
that you put on a standard circular saw that lets it run on the track
and plunge on the hinge. Not going to be as nice as a purpose made
plunge saw but should do most of what one does and beats paying a
plunge-saw price.


Sounds like a good idea for a product. They make bases for both circular
saws and routers to run on tracks. It doesn't seem like that much of a jump
to a product like you are describing.
