PSA: This locknut can ruin your day!

Post by Srick »

Image

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!
And you know there's a YouTube video of a guy in Mexico who builds a guitar only using a machete, right?

I've been disappointed with my Bosch Colt lately for that reason and also that the fine adjustment mechanism doesn't work either. I'm using a Ridgid in the binding rig now.

Thanks for the heads up. I don’t use my Colt for binding anymore but do occasionally need it for an odd job. Will check it today.

I know. I almost messed up a guitar because of the same issue. Luckily I noticed it was loose and tightened it before disaster struck. Now I check it every time I use it. Not a good design.

I've been finding it hard to get a wrench or socket in there to tighten that bolt.
