A 360F WITH A SHADY PAST

Here we have a '67 360F that a Forumite purchased through the mail from a certain, ahem, large Music Exchange in Chicago. When he received it, it didn't seem to be as represented ("mint, original"). He showed it to me. There were signs of extensive work, done very shabbily. There was something rattling around inside. We shook it and out fell a Bondo "worm"--some Bondo had been squeezed through a drilled hole, had hardened and broken off. Bondo "worm". Uh-oh.

Most of us know that Jetglo on an old Rick is a good sign of a bad repair job. This was no exception...the back had cracked in several places, and the pickup selector switch had been punched in. These problem areas had been filled with Bondo, slathered on, and not sealed before a cheap enamel paint job was applied very thickly--you could see and feel the "step" between the black areas and the binding.

Once I had the guitar stripped, a nicely-grained guitar was exposed, and evidence showed that the 360 was originally Fireglo. Must've been gorgeous, but there was very little FG left, and refinishing it in FG was out of the question because of deep staining and some repairs that had been done with epoxy filler, including a substantial gash in the headstock volute on one side.

These later Fs are different animals from the early. The earlies are billet-type guitars, routed out of a chunk of maple with a back added; the later Fs are built like a Gibson or Gretsch and are true hollow-bodies with bent sides and glued-up front and back. More Gretsch-y in tone, too.

The back showed its cracks after the black enamel and Bondo were removed:

You can see traces of the original FG in the crack here:

Image

Below you can see evidence of someone using a "jitterbug" (autobody vibrating power sander) to sand the Bondo and wood--those corkscrew tracks are a dead giveaway:

Image

Here are a series of shots with the back removed. The tailblock was rebuilt prior to gluing the new back on:

The new back was rough sawn and then the area at the heel was cut back to the correct profile before the back was glued in place:

Image

Image

Image

Image

The back was then trimmed to fit exactly, once the glue had dried, using a flush-trimming router bit on a table router, and then, using a 1/16" rabbeting bit, had the first binding step cut on the same table router:

Image

Image

Next, the second step was cut by hand with a Dremel tool to which is fitted a special collar:

Image

Image

Finally, things are beginning to come together; the first layer of binding (checkerboard) is fitted and glued up, with a joint in the corner of the heel and another at the bottom, center:

Image

Small brads are used to hold the checkerboard in place; their holes will be covered by the white binding which is the next layer.

Image

Image

...And now it's time for a rest. I don't have any of the celluloid binding in this width in stock, so it's been ordered and when it arrives, we'll continue. This guitar will receive a new, proper, glass-smooth JG paint job. It also has a badly-worn fretboard, so I'll be making a new one, sparkle inlays and all, while we wait for the binding to arrive (it can't be shipped via air, as it's hazardous, so it'll be a week or so before it gets here.) But I've got lots of other stuff to work on... :roll:

Great job as always Paul.

Two questions:

1/ What is the process that you used to remove the back?

2/ How do you post such huge photos with such high resolution?

Brian:

1. The black was first chemically stripped, then sanded by hand to #150 at this stage. Later, after sealing, it will be sanded to #320.

2. I shoot very large (2560 X 1920) originals, then process them in Photoshop CS, to optimize contrast and sharpness. I then reduce them to 600 pixels high, and load them into my Photobucket folder. I then link to that folder, which places the photos onto the RRF page.

This is really good stuff, Paul. I'm a real clutz with tools, so I really admire those who display great skill and craft. Do by all means, keep the updates and photos coming.

Paul, do you use hot vinegar to loosen old glue joints for removal, or is that strictly a furniture repair techninque that's too harsh for fine guitars?

Amazing work and fascinating tutorial, as always. I too look forward to the next installment. :D

Gretsch-y tone, eh? I might have to pick one of these up eventually. That's my other favorite brand. :D

Thanks for the answers Paul, but I believe you misunderstood one of my questions. I was curious how you delicately (or maybe not) remove the back of the guitar without compromising the sides.

Your photos btw are incredible. I'm borrowing a line from Rod Stewart, every picture tells a story.
