Could someone please explain how these are used in the guitar building process.

It is probably simple and obvious, but it is eluding me.

Thanks.

Guitar Radius Dishes | Guitars | Kitchener / Waterloo | Kijiji







Description
I have a full set of 1" HDPE plastic, CNC'ed concave radius sanding and assembly dishes for acoustic guitar building. As a builder myself, I found that the MDF dishes available online ($100++ US) don't stand up to the changing of self adhesive sandpaper and can be problematic during the glue up process in a go deck. I wanted to create a life time tool that is accurate and impervious to moisture, glues and the removal of sand paper adhesives. The commissioned result was the creation of very high quality CNC cut, balanced dishes that will last a life time. Each disk is pre-drilled with a 1/4" centre hole for accurate indexing. One disk from each radius set is designated for the application of sandpaper and use on a low RPM turntable (or manual sanding) and the other is for the go deck glue up process. The plastic is expensive and combined with the lengthy CNC work required they are a little on the pricey side but you get what you pay for; a life time tool!

Would like to sell as a complete set:

[email protected] 24" Diameter, 16ft concave radius;
[email protected] 24" Diameter, 24ft concave radius;
[email protected] 24" Diameter, 30ft concave radius.

Price is firm at $1500 for the complete set.

I don't know about 'most,' but yes, good guitars are generally radiused front & back. Building it in the dish let's you shape the radius in to the front or back when you're installing the bracing. Also good for sanding the radius in to the braces prior to installation etc.
