Sanding Dish?

[carousel182]

i was thinking about this last night for several hours the only easy way that i could come up with would be on the lathe, cut out a 25"(or whatever you want)radius out of mdf and attach sandpaper to it, and while the lathe is spinning put it on the outside of it, where you would be carving out if you were carving out a bowl or a plate. another idea i had was to attach the tool to a 25' stick so it can only go a certain distance(in a 25" radius motion).

and yes i think my lathe is big enough to pull this off.

any easier ideas?

thanks

A router jig like everyone else uses?

Pictures at MIMF.com, Luthiersforum.com, or google for 'guitar radius dish' or similar, and you'll find plenty of places.

Basically, an arched template for the router to ride on, router, more or less done.

Picture of my setup, in case that helps a little. The arches were made based on a template/spreadsheet in the MIMF.com library, but I'd probably use a long compass setup (google will reveal all, I think it's Jonathan Sevy's website) to mark out the arches.

Ummm....to make a wooden plate so people can throw money into it in the street? That's how short of cash I feel as a lutheir sometimes too :-(

Making acoustic guitars. It's in the wrong section, really...
