I hope some one out there has some advice. I have a Craftsman Router Model 315.275000. I have noticed that the locking mechanism that controls the depth of the router bit doesn't really lock. I've cleaned the thing I have even taken it apart to determine the problem and it comes down to the fact that it doesn't clamp hard enough. So I was hoping someone out there had some ideas on how to clamp the thing in place in an effort to keep the bit depth from changing while I'm in the middle of routing. I don't want to toss the thing it was a gift. But I gotta tell you I am really dissappointed in the quality of this thing. Sears was no help. Thanks in advance for any ideas on how to fix the problem.
