a homemade soundhole rosette router

So, here´s another little homemade tool that has been with me since guitar number 1 and hopefully it´ll stay forever.
Its made out of clear vinyl or plastic, 4 bolts with nuts and some araldit epoxy glue. Its run by a chinese made dremmel copy which has also been with me since guitar number 1

Here you see it in use with a soundhole cutting bit.
