Closet Boffin? Wasn't that Boris Becker's problem?

Really good to see a warts and all build blog...
Apologies for adding to an off topic few moments...

Be my guest! Anyway, I think you'll find I was asking for it; trying to cover the fact I've been mending a bureau for a few days rather than working on the guitar!

My sympathy goes out to you; I know how it feels...
I'd rather be building guitars than doing my desk job.
Mel.

Awaiting the customer's cabinet hardware decision on the bureau so set out on a (not at all) bright Monday morning with nothing but the guitar in my sights. I started by cutting a hole (with a drill-saw) in the side of the guitar - which normally elicit's the question, "What's that hole for?" and the answer, "That's not a hole; it's a 'port'." As you see, I somehow almost missed the reinforced area I was aiming at but I think that's good enough! I then switched my attention to the back of the guitar. It first of all needed cleaning up around the braces, where there was rather a lot of excess hot-hide glue loitering, with a hot wet rag. After a quick scrub, I gave the whole thing a light sanding to ready it for the application of some more polish. (I also gave it a once over with potassium bichromate to cover the bits that had been left bare by the various ungluings and gluings that had gone on): I avoided the braces since I hadn't been too pleased with the effects of the stain on these previously. Next a few rubbers (as they say) of SPB: ... and then a few more: Now I realise I'm not making a perfect job of this polishing but, after all, we are talking inside a guitar which nobody will look inside (since they can look at the pictures here instead) so I'm just looking for a reflective surface which will keep the water out and feel nice if you put your hand in and stroke it. The next stage I would normally leave till the next day but... I cut it back with 320 grit paper ready for a final rubber or two in the morning: It's an exciting life! Finally today I did this: Pretentious? Ego? I also, by the way, remembered to make a note of brace heights before I close up the box: though the brace-ends that appear to be jointed into other braces and into rims are, in fact, all free-floating in reality. I'm afraid I've also had a bit of an idea. I was messing around with drawings of the sound-hole and wondering how to reinforce the annoying little bit I'm left with between the end of the heel-block and the hole. In this picture it's the fiddly little bit to the left of the truss-rod hole and it's very difficult to cut a little piece across the grain like that especially when it's only there for show really: Well, as I say, I was having these thoughts - thinking about the next guitar if I'm honest - and suddenly it came to me: The hole doesn't have to be round! (I know it's a bit of a shocker but you'll have to "bear with me" - apologies to COGs - on this one). You see, if I just cut this bit out altogether right up to the brace at the side and up to the end of the neck/heel-block, then it leaves a hole which is not round but a perfectly acceptable shape, especially since it disappears under the end of the fingerboard. Moreover, it affords me the possibility of some unusual decoration. I'll stop talking and show you a picture instead: The idea would be to continue the pattern all the way round the guitar and then loop it back round the hole. It also reflects the way the guitar is put together with the neck plunging into the end of the box like something from a biology lesson. A bit "Arts and Crafts" the way it shows its workings, I thought. Anyway, that'll have to wait for the next one I make because I'm not about to modify the rosette at this stage of things.

A quick final rubber this morning and the inside was very shiny, if a little coarse: Plenty of room round the edges for glue so why not stick it on to the rest of the box? First check that everything fits.... It doesn't. The ends of the braces just refuse to slot nicely into their housings (as they did last time I checked it). So I spend approximately an hour and a half sorting that out. Now check the humidity: Lovely and low. Now apply the glue - fish glue!! ( dramatic music - you know, that Jaws theme) Since the dehumidifier was sucking the moisture out of everything even as I applied the glue, I coated both surfaces just to make sure it didn't dry out before it got a chance to stick; I can worry about cleaning up the mess inside at a later date. In fact, you know, I think next time I'm going to use hot hide glue; apply the glue all the way round on both surfaces (in a leisurely manner) and then work my way round with a warm iron, bit by bit, cramping it up as I go. Even though hot hide glue has a reputation for creating panic in case it chills too quickly, I find it all rather less frantic as long as you are prepared to remelt it and take your time and it virtually cramps itself once it has chilled a little; you certainly don't need top leave it alone for 12 hours in low humidity anyway. Here's how I left it this evening: It should get at least 19 hours to sort itself out before I start fiddling with it. Let's hope I got everything in the right place. So while that was going off I turned my attention to the bridge. Luckily I produced a sort of template last time so that it should all be a bit simpler this time. It's made of brass: The slight angles at top and bottom are router guides for the saddle slot: And, finally, here's the blank (laburnum) cut to shape: Got to help with a tarte au citron now. Bye.

A question: what should I use to stick my label inside the box, the surface of which has been shellacked? I've got various things that might do it but I can't remember what I used last time; it may have been fish glue, in fact...

That is a pretty rosette.
Cue another pat on the back...

Glad you like it because it's going to be the purfling as well if I can get it to obey my demands all the way round the box.

Hadn't noticed before...but does your earlier guitar look a bit like Hitler?

Seriously, Rob, I've really enjoyed this thread. I admire your approach and thinking about making a unique guitar. Honestly, can't wait to see and hear the finished article. Well done.
