I made one of these tools today. Man, I'm proud. Its the first woodworking project I've actually finished. LOL.
I was getting ready to glue on my cloth and happened to see the duct tape out of the corner of my eye. I did Red Green proud! Let me tell you, there was a kitchen hand towel breathing a sigh of relief!
Also, my file was too wide to pound into the groove I cut, so I took a second pass at it. Now the groove was just slightly too wide. Fortunately, I had some epoxy on hand.
Anyway, thanks for posting your tutorial Brian! It's helped to build my confidence with my table saw a little bit, too. It only cost me 6 bucks to build!
Next, I'm going to make the fret bender.
