'67 366/12 Restoration Questions....

Hi all...

I heard this might be the place to post for technical luthier-type queries...?
Hope so...

Anyway, I'm looking to restore my '67 366/12 (see this thread: viewtopic.php?f=22&t=395144 ), and I have a few binding questions:

Can someone give me the dimensions of the finished back-binding on a '67 360 or 366???
Total binding height and thickness?

Somebody destroyed the existing binding (I have replacement binding), and I need to re-do it...

They also wiped out the sound-hole binding.

What is the thickness of that sound-hole binding, and where did they usually locate the joint?
Anyone have a close-up pic of the joint?

Thanks in advance!

Total binding height should be about 9/32" (.280"), but can be slightly over or under this dimension. The outer edge should be only slightly "broken", not rounded off. About 1/32" radius is correct. Thickness is nominally 1/16" (.060").

The soundhole binding is 1/16" thick, by however thick the top wood is. The seam can be in roughly the center of either longer curved edge. Inner edge is most common.

I've restored a couple of these, and the binding back then was genuine cellulose nitrate (celluloid). To use the more commonly-available extruded ABS binding would be non-original.

To source genuine celluloid binding, try:

Yep, Celluloid is the stuff.

From my experience, celluloid was WAY easier to work with too. It softens up nicely when you're using acetone as an adhesive (well...not really adhering, more like melting the plastic).

Downside is that shipping is quite expensive as celluloid is classified as "highly explosive, haz mat" for shipping purposes. Axinc is a great shop. :)

Got some from Rickenbacker 20 or so years ago....
See: http://i231.photobucket.com/albums/ee22 ... 050981.jpg

OK, here's the problem (or one of them) on this puppy...
It looks like someone drastically thinned the back down, taking the binding down to a mere 3/32" or so.... :shock:

I'm thinking of building the back to it's former glory with a veneer of hard maple, then re-cutting the binding to the 9/32" that it wants to be...
See a pic of the existing binding here:

So, I'm wondering--just to make sure--what is the thickness of a '67 body measured just to one-side-or-the-other of the tailpiece??
I'm getting around 7/8" on mine--see:

Sure would be nice to find an old fingerboard!

OK, thanks...!

Umm...yes... What you've got there is a vintage Rick with checkerboard purfling intact, but no white binding over it. This suggests that the guitar was thinned as well as having its circumference shaved about 1/16" all round.

You should have a stepped rabbet around the outside, with a layer of white celluloid over an inner layer of checkerboard purfling.

The white stuff you can get from Axiom. The checkerboard is pretty much unobtainable, although it's being sold on eBay for ripoff prices (over $1.00 per inch!) .

Got it...
Can you direct me to any online sources (or a book I can buy) that would document this with some closeup pics??
I guess I need a Ricky version of the Blackguard Book... :wink:

I've searched the Register, but nothing that detailed is showing up...
Thanks!

Great! I know several people who have bought some recently straight from the manufacturer in Germany as well.

Bruce, here are a few closeup photos of what the binding process looks like. This was a 360F that I restored for Graham Griffiths a couple of years ago.

Here's the stepped rabbet running around the circumference, that I made reference to:

Image

The so-called "checkerboard" purfling (from shellex.de) runs in the inner rabbet, which is typically cut about 3/16" X 1/16":

Image

Over this goes the white celluloid binding from axinc.net, which is then scraped and sanded to be flush with both surfaces:

Image

End result after painting looks like this:

Image

Sometimes headstocks are bound with checkerboard, sans the white outer binding:

Image

I hope this gives you a good idea of the correct "look"!

OK, if someone has one kicking around and handy, I'm looking for a measurement for the width at the widest point --measuring side-to-side--of the back of a late 60's 360 body....

I'm trying to figure out just how much wood this guy took off from around the rim....

Thanks in advance!!

You don't have to look too far...it would appear (wood appear? :lol: ) that the edge had 1/16 taken off, to remove the thickness of the white binding down to the checkerboard purfling.

Tip: Remove the checkerboard and re-cut the rabbet for the checkerboard to 1/4"-9/32" wide X 1/16 deep with this type of router bit:

http://www.stewmac.com/shop/Tools/Speci ... r_Bit.html

Then use this bit in a Dremel to cut a new rabbet for the checkerboard, 3/16" wide X 1/16" deep:

http://www.stewmac.com/shop/Tools/Speci ... nding.html

This will give you the stepped rabbet. Checkerboard goes in the inside step, white celluloid in the outer.

You may have to re-radius (round over) the front to blend with the sides, if it hasn't been properly done already when the edge was buzzed off by the previous nut.

If not, just scrape/sand the binding to be flush with back and sides and Bob's yer mother's brother.

Oh, yeah, and then you'll have to refinish the guitar... :wink:
