How to set bit height in collet?
Ok folks, quick question....
I have a bunch of Craftsman routers. In my table is the 14 amp Craftsman professional router. While using it the other day, I noticed a bit of vibration. I removed the bit, cleaned the collet, and reseated the bit. Then I noticed a problem....
On most of the Craftsman routers, there is a spindle lock so that the bit can be tightened with one wrench. However, the lock protrudes enough such that it hits the shank on the router bit when tightening (and consequently, skews it just enough to induce runout, thereby causing vibration). From the safety side of things, this seems almost as bad as bottoming out the bit, as anything that prevents the collet from tightening perfectly seems dangerous.
If I raise it above the spindle lock, the bit runs true, presumably because there is no longer a side load while tightening. But the problem is, now the bit is considerably higher in the router, which is not a good thing for safety reasons.
I read the owner's manual, and all it says is to insert all the way into the collet and then back it off a little. I can't imagine Craftsman designed it so that I have to keep the bit this high, but I still wanted to check.
Any thoughts or recommendations?
