Background:
I last used my Bosch Colt router when cutting the binding channel on my latest build. I had no idea why, but the router bit suddenly dropped and ruined a good inch of so of the channel. Needless to say, I was not happy in the least. And I figured it was operator error. Of course it was. It always is.
I hadn’t used the router since that ugly day. Today, I picked it up to fabricate a caul to glue the bridge and (!!!??****##$$ what the - what the!!?) it happened AGAIN! This time I figured it out. The router’s height locking mechanism may seem tight enough, but with enough load, it slips and ruins your work.
I tightened the locknut and all is well. Don’t do what I did - tighten those nuts before disaster strikes!
