These dishes are well made and work great for radiusing guitar backs and tops as well as radiusing guitar braces too. I used this for my first two guitar builds, and it made the whole process much easier. I used these in my go-bar deck when gluing on braces to the top and back. It was also used to sand a radius into the guitar sides before gluing on the back and top plates to the sides. These were also priced fairly if you compare it to Stewmac. The only complaint is that it took about a month to receive, but I am very pleased with the product.
