I'm not sure. What makes the TS special compared to a jointer (or
planer, or router with a straight bit) is that the blade extends
back several inches from where it cuts, and it doesn't have a reference
straightedge without the fence.

I guess the best I can think of is ripping on a TS (or a bandsaw)
with the fence in place, but with the waste side running along the fence.
So, you have aboard with one straight edge (call it A), a
rough edge B to be trimmed, and you run B along the fence.
The resulting trimmed edge C isn't going to necessarily be
parallel to A.



Where things get dodgy (or my thinking about 'em does) is
when you have A and B already parallel -- trimming it with B running
along the fence WILL give you a new edge C which is parallel to A.
Jointer is supposed to go the same way (i.e. the "rip on a TS to width
plus a hair, trim hair with jointer" approach). But I have a gutt
feeling it won't be necessarily parallel to A unless the operator
has impeccable technique.
