I made this little gizmo awhile back, and figured it was about time I post a pic or two to explain it. It's pretty straight-forward. I made this specifically for routing the binding ledge on headstocks.

Two 1/4" pins insert into the router table baseplate, and one pin centers over the spiral bit.


There are actually 3 of these that I've made - identical except for the pin sizes - 1/8", 3/16", 1/4".


I have four different spiral cutters - 1/4", 5/16", 3/8", and 1/2".
This one was done with the 1/8" pin and the 3/8" bit.


It's easy to make, and can make this task very easy.

Nice looking setup, Don. Looks like it works great. That will certianly be a unique banjo head
One question: What holds the pin in place?

Bruce,
I thought if I need to use this neck on a guitar, I could always buy some small clamps and clamp on a couple extra tuners.

The pins are held in place by pure friction. I drill a hole in baltic birch via my drill press, and there's no slop. Then I have to hammer a pin of the same size in there. It stays put with no problems. Very tight.

That's a very nice setup Don. I really like things that are done simply. I noticed that a lot of Charles Fox' jigs were designed the same way. Very simple, but also very accurate.

I tend to overthink things, can you tell.

I'm trying to learn to do things the simplest way.

That's just the way my simple brain works I guess

Congrats Don, nice work. How does it work? Is this simply giving a guide to rub against, set at a certain depth? Nice setup.

One more pic when you get the binding on the headstock, please.

Don,

Very nice. Beautiful looking neck and headstock. I agree with Bruce, some more pictures would be great!

Don...This is great! It may be simple to you but it just served as a significant lesson to my continuing education in the use of my router table. Thanks so much for sharing!

Just a few clarifying questions:
1) The pin center always centers on the bit center?
2) The different pin/bit combinations define the width of the ledge?
3) The depth of the ledge is controlled by the bit height.
4) I think I got it! Now all I need to do is lay it all out accurately...no casual task for me.

Lance...this is worthy of inclusion in the Jigs section. That way I can refer to it if I ever get back to the shop.

JJ....you got it exactly. The first thing I did was drill the locator pin holes using the baseplate holes as a drill guitd. With the wood blocks containing the 1/4" pins to mate with the 1/4" holes in the baseplate, I mounted the blocks onto the baselplate. I used a 1/4" bit in the router to locate the hole for the 1/4" pin, a 3/16" bit to locate the hole for the 3/16" pin, and an 1/8" bit to locate the 1/8" pin hole. This way, the router creates the concentricity of the pins with the bits. The pins are always centered on the bits.Don Williams38424.8063657407

Thanks Don. Your followup instructions just made it a much more casual task for me! This forum is sooooo cool!

That's pretty cool Don, I wonder if that could somehow be used to route a slot head
