I had this dilemma one time and decided against it,in that the holding power of the chucks surface area is diminished tremendously and is relying on the chuck to clamp on the cutters which are soldered onto the tool. They weren't made for that type of pressure and might chip or damage or come loose in operation.I Have a long 1/2" flush trim bit. Is it okay to run it down in the blades down in the MC? I need to get it down so the bearing will ride the template. It looks like it would be okay but I am not sure.
Mike I am only using it in my router table.Don, if you are using the router free hand you can easily make a thicker sub base plate and attach it with double sided tape for jobs like this.
The first time that I came upon such a problem I purchased a bit similar to this one.

Chuck Stick won't let me buy any more of those cheap bits. :grin:This is a common issue if you do much pattern routing so it pays to have a few different lengths of both flush trim and pattern bits. In the long run it's easier to have the bits than to have to monkey with spacers. Yonico/Precision Bits have fair decent quality bits for reasonable prices.
