Router Bit for Cutoff work?

List:
Okay, this gonna sound weird . . but every router bit in my stable is of the "Edge Forming" or "Rabbetting" variety.
What I Wanna Do:
I'm working with some panels that are beyond my "Comfort Level" for tablesaw work. I've some baltic birch plywood that I've cut to rough size, laminated to ~1-1/2" thickness.
I now want to cut these to "Finished Size."
I think the best way to do this is with a router--some contours that I can use a masonite guide to cut.
What's the best way to do this?
A top-bearing flush cutter, making my guide the exact contour?
What about long straight cuts, running the router along a straight edge? That's something I envision doing fairly frequently--it's be easier to control than my current circular saw method. Is there a special bit for that or would I just use a straight cutter?
Thanks.

Its commonly done for large circle cutting so it should work fine. The only thing is is will be time consuming, as you have to make multiple passes.

Keep in mind that if you clamp a straight edge to the side edge of an 8' board with clamps at each end, the darn thing is going to give in the middle very significantly.
I use a spiral bit. You can get one that throws the chips towards(for mortising) or away from the router depending upon the intended use, in this case you would want one that throws the chips away(down) from the router. I prefer to use a 1x10 board as a router guide when I do trimming. I marked a line on a small piece of wood that shows me exactly how far back to clamp the guide to get a precise cut.

You're at the limit to pattern rout; much thicker then shaper might be called for. BB is tougher than hell to rout. For the short run make pattern from 3/8 or 1/2" MDF and maybe stage rout. Stage trimmers (shank bearing guided) at the http://www.patwarner.com/patternbits.html link. ************************************************************

Honey? Pat Warner . . . THE expert, tells me that I MUST buy a shaper for this project. It's only around $1200 or so . . . .
Thanks Pat.
Think she'll buy it? :)

Rough cut (as closely as your comfort level allows) with anything, so that you're just cleaning up the edge with the router.
A 12" wide piece of plywood (watch for voids/edgeband) makes a decent clampable/screwable straightedge.
