I have a second hand Porter Cable single speed router that I have under mounted to a router table I built two years ago and it works great. I bought a raised panel bit and just now looked at the router speed chart that’s been on the table since I built it. First thing I noticed is that it recommends 17000rpm (going from memory on this) for regular but sizes (1/4” straight bit) then I read that my router runs at 22000 rpm. Is that ok? Next, I saw that I should be running it at 12000 for this panel bit due to its size. Do those variable speed controls work on single speed routers? Forgive my ignorance, I don’t know where to read up on them. If not, do i really need to spend $200-300 on a variable speed if it’s a mounted router?

22,000-24,000 rpm is fine for anything up to about an inch. If the manufacturer of your panel bit recommends 12,000, then that is probably about as fast as you should go. Most brush type motors can be used with a speed control AFAIK, and I know several people who use the HF one (<$20) without any problem.

+1 vote for the HF speed control Brad recommended. I may have the same setup as you. A 690 porter cable but mine is hooked up to the HF speed control. I then dial the speed accordingly. Usually the larger the bit the slower you need to go; think about it, as the diameter of the bit gets larger for the same RPM its actually traveling a lot faster. Do a google search and you will find recommended speeds. However this wont help with your or my setup as the speed control doesnt actually give an rpm reading. What I do is usually run a scrap piece of wood. I start slow and if it bogs down a little too much I dial it up, burning and you’ve sped up too much. Also some woods are more forgiving than others.

To answer your question about the speed control, as long as your router doesnt have a “soft start” then the speed control should work fine
