This is the kind of letter I enjoy getting from customers:
I'm really happy with the jig, works like a charm, was real easy for me (likely easier since I used to drill at a pro shop years ago), and I've changed out over 20 thumb slugs with it already.
Just wanted to let you know that I successfully changed out my #5 pitch plate bushing with no problem, luckily I have an arbor press that really made the process easier. Other than that, I have drilled out over 50 balls, including thumb slug changeouts and drill outs for plugging without a hitch. I'm really happy with the product! I started using the Pro Edge Custom Thumb Molding system and I've never had equipment that fit so good ball to ball!
