Is there a rule of thumb about the maximum size of router-bit that should be used free-hand? E.g Would a 25mm straight cutter be too big?
 
byron i have used a 25mm cutter free hand to remove the waste from some large tenons i found it ok. it is usauly stated in the catalouge whether they need to be used in a table or not.
 
thanks chaps! I took delivery of a 25mm router cutter and my thoughts were "that looks unwieldly!" but now I know it's safe to use free-hand I can stop being a girl about it :)
 
I think it's more a case of not using a big cutter at too high a speed rather than not using one at all. I have Titmans biggest straight router bit, it is about 50x50 and I used it for rebating before I got my spindle. It worked well at low speed but if I forgot to turn the router speed down the vibration made it scary as hell, and that was in a table.

Thats why i use the xtreme xtention , you balance it in the collet to stop the vibration .

How does that work, I would have thought an extension would make things worse due to deflection I definitely think you need variable speed for the bigger cutters.

Yes you still need to adjust the speed but you balance the xx in the collet . It's a great bit of kit and makes changing over cutters a very simple twist of an alan key .
