Official Luthiers Forum!

Thanks again Tony Karol for turning me on to your method/jig. I definately was over thinking it. Your jig is nice and simple, my favorite kind.

Thanks Chris, I'm trying to figure this out and I needed to see it done. I'm still struggling with the location, any tips?

Can't really say since this is my first. But from reading some articals the size and location can matter. Some say to make the soundhole smaller in relation to the port size. From some that I've played it doesn't take much to hear the sound. I like them in the upper bout. Some also say the shape can make a differance too. So I'm playing it safe and somewhat simple to start with.

Looks great, Chris. It's great to see you back in action!

Nicely done Chris .. you should mention the slots in the plexi are required to allow you to centre/position the template(or not centre it as design may call for) once the jig clamps is tightened onto the guitar body.

I used the same method of attachment years ago when designing my tail wedge jig .... it was just too easy not to use it again when needing a template method for sideports. Easy to make other templates for different shapes as well.

I made up 5 more template blanks just for that reason of future shapes and uses. I used polycarbonate for the templates, I have a hard time milling plexi due to it wanting to melt on me and gumming up my bits especially on my pencil grinder that I use in my ellipsograph, pantograph and inlay duplicator which all can be used to make the template shape of choice.
I found out that I need to open up the threaded rod through holes a tad more to allow for the body taper. You can see how it was racked a bit when removing it.
Thanks again for your help, a picture is worth a thousand words.

Sweet tutorial, Chris, as usual.

Love the music - but I think you need ear protection from the music too, if I can hear it loud and clear over the router!

Or maybe it's a quiet router?

Or maybe it's a quiet router?

I couldn't quite tell, did you cut from the center out, or just at the edge of the template?

Drop the router into the centre of the cut, then move out to the edge and follow the template. I use a lam trimmer, non plunge, and just push it thru to get started ...
