Scott, Please do not take offense to the following:
Sandwiches are for eating only. Sandwiching a workpiece between two fixed objects [read: fences] will get you fed, but it will be wood and that ain't ketchup (catsup); but rather it is blood.
Please DO NOT EVER DO THIS!
Occasionally, someone will say, "Oh I do it all the time", or, "I don't see the problem with that". Similar things get said for numerous activities, but that activity is EXTREMELY DANGEROUS.
FEATHERBOARDS are your best route! ESPECIALLY in consideration of the extremely high speeds (RPM) of a router!
