What's the quick, easy, clean way to rout or otherwise excavate square-ended slots in a slotted peghead? Such as this... http://www.kevinkastning.com/photos/DKK_headstock1.jpg If there's not a quick, easy, clean way, what's the other way? Cheers, Matt :)

I haven't seen too many motorized cutters that will cut square corners except the powered mortise cutters Do you think something like that would work used with a fence maybe.John How38705.6362962963

That would be my recomendation but beware: you have to get the mortise bit perfectly parallel to the fence or your get a facetted cut. I'd recomend using it only for squaring up the ends and then route the slots as usual. You can also but attachments for your drill press that do this for about half the price.

What I would love to see is a jig that let you cut perfect ramps in these things every time..... Matt... I just cut them with a large diameter bit first, then a small one to get back into the corners as close as possible then use a chisel to square up the corners. Not a very elegant process to be sure, but it works.

I wouldn't used a power morticing bit. For threw holes they can make a mess out of the exit side. I cut square edges all the time when timber framing and furniture making I use a router to cut the slot (up-cut solid carbide spirals) and then use corner chisels to clean them out. My large corner chisel (which wouldn't work all that well for guitars) came from a specialty supplier who does not have a web-site but my smaller corner chisel is this one (the 3/8 inch unit) that I did by from Lee Valley (the large Sorby is too clunky, even for timber work!).

MATT I use a jig from Chris at luthier tools. http://luthiertool.com/combo_slothead_fixture.html It comes out pretty close to square. It is an awesome jig for both slotting and placing the tuner holes. Andy See attached pict of my current guitar peghead. It is on a web page because I could not get it to upload. http://www.lazydogguitars.com/headstock.htm

That tool is on my must have list, I like the fact that you can use the same tool for both steel and classical slots.. Buying one right after Xmas... Speaking of that (sorry matt don't mean to take over your topic)... has anyone tried their binding tool?? Looks interesting... -Paul-Sprockett38705.783287037

[QUOTE=Sprockett] Speaking of that (sorry matt don't mean to take over your topic)... has anyone tried their binding tool?? Looks interesting... -Paul-[/QUOTE] I really like the look of the binding tool. Because of the dual side bearings it references off the side and not the top/back. That is a good thing! The bad thing is that I'd need to buy about 5 of them. as I like to set up one and leave it be. So that would cost me $1000 plus the cost of the routers/bits. Me thnks I'll stick to what I have now...

Ditto on Chris' slothead jig. It's extremely well made and precise. I've used it on 2 heads so far and is simple to get high quality results.

to use it for both steel and classical you need to order the combination version which has both templates for slotting and both sets of bushings for tuner holes. Andy

I also have the binding tool and it is OK. I am having a problem with it in that unless you hold it tight against the sides, it can tip over the edge of the top a bit and cut too deep of a slot. I think I just need to practice with it on scrap and get comfortable with it. Andy

Andy... If you took his design there with the bearings riding on the side and hooked it up to something like LMI sells (that rides up and down) you would have an idiot proof binding machine, now to make it better put in the new Bosch laminate router with the microadjust height action and you could get really precise. To John's point if someone would make one with either a digital dial or put a fine scale on it then you could just write down your settings and use one tool adjusting it for each operation would then be a snap... Something to think about.... Man I wish I had access to a machine shop sometimes -Paul-

Not to derail this discussion completely, but one more thing regarding the binding jig: I have posted pictures of my home made jig that looks a lot like this. I get better results when I clamp the jig in a vise (so the bit is oriented horizontally) and turn the guitar body around. Many people like to do it this way, I know Martin does and I saw Julius Borges had a similar set up as well.
