[QUOTE=Stick486;1675361]one pass cut w/ a ¼'' on plywood is a bit much on the bit....
rough cut your plywood w/in 1/8'' w/ a jig saw 1st and finish cut w/ a larger dia bit w/ 3 or 4 flutes.....
now you'll see a marked increase in speed of cut and no threat to power.....[QUOTE]
That's the way I do it. I use a 1/4" shank bit, 1/2", about 3/4" long cutter. All I use, normally, is 1/2" plywood (or as close as I can get), rough cut, trim, no problems. But I don't think I do 36" per minutes, even so, but I've never timed it, so could well be going that fast. Long ago used to hog out 1/2" plywood for some projects I was doing, and didn't go anywhere close to 36" per minute, but was only hogging about 3" cutouts. Even then, used to stop once in awhile, poke out the sawdust, then go again. Oh yeah, my routers are all small, old, low power, Craftsmans, made by Ryobi. For what I do, works just fine.
