Trim work, the fun never ends! Every luthier knows the unadulterated joy of scraping bindings.

It helps to get the whole body into it.

These little cutaway corners sure look nice with all their miters, but they take some time.

Thanks for stopping by.

Lookin good fellas, what do you think Stan?

SJ VanSandt 08-31-2018 05:27 AM

I am kind of in awe of these guys - and all good luthiers, when you get right down to it. So many little details that have to be executed with patience and precision, so much work that looks like, well, hard work. I can mow a lawn: any mistakes I make usually grow back. I couldn't build a guitar in a hundred years!

Finally for Stan the long awaited curly mahogany purfling! Itís actually fully installed and looking great though I have only have work shots now.

Bending a full size of 1/16Ē solid purfling is its own challenge to make it fit the channel perfectly.

Hereís a close up to show the channel between the black/white/black purfling strips where the Teflon spacer used to be. We bent two solid strips for each side of the top and then inlet them into their channels. We used a watered down glue to secure the wood in its place after the fact. This kept anything from swelling during installation.

Thanks for following along.

Tantalizing! I don't quite follow about the watered down glue - it seems like water would make it swell more. But I trust you - I'll bet you've done this before, once or twice.

nacluth 08-31-2018 08:52 PM

To be certain, itís the water in glue that makes the wood swell, but sometimes we will put glue in the channel first and then seat the wood on top of it. We felt like with this long of a piece that there was a chance in that scenario that the wood (either the b/w/b strips or the mahogany) might swell up too much before it was fully seated. So this time, we fit the mahogany first in the channel and essentially wicked a more watered down glue in the joint while everything was in place. That way if swelling occurred, it was more or less securing the wood even more.

Perfling and binding done - off to the finisher! (Or the spa treatment, as Tom says.)

Stan, I got to see this and Ryan held it a tapped it for me (don't worry, I did not touch it) and the box sounds amazing. There is no way that this thing is not going to sing like the angels. I think the bridge color is going to be perfect once the top has some finish and darkens up a little!

Be at peace during your wait because you will not be disappointed!!!!

SJ VanSandt 09-04-2018 08:17 AM

Ha! I'll be at peace when the angels sing for me! ;) No, actually, I'm enjoying this process so much that I'm not experiencing much anxiety. The difficulty is not jumping in the car and driving over there every time they post an especially interesting picture. If they lived a hundred miles closer to me I'd probably be bugging them to death.

Some updates before the FS heads off for some R&R. Weíve got to get this neck fitted to the body which is its own process. First up is making sure we have the right neck angle.

https://s19.postimg.cc/y11pgaz2b/9_D...EDE90_B6_F.jpg


Once thatís set, weíll cut the heel angle. We reinforce our heels with a dowel of mahogany. Hereís the drill making room for it.

https://s19.postimg.cc/3wd8uy1oz/BB1...0_FE0_AEDC.jpg


That makes it possible for us to put inserts into the heel to catch the bolts.

Then we relieve the heel so it will mate well with the body.

Thanks for watching.

SJ VanSandt 09-04-2018 04:50 PM

I'm glad I checked here before I answered your email - I didn't have a clue what was going on! I didn't know about the mahogany dowel - that picture really had me puzzled. I assume the end of that is covered by the heel cap?
And I still don't quite get what's going on in that last photo. How exactly is the heel being relieved? Wouldn't it be enough to just reassure it?

nacluth 09-04-2018 05:58 PM

Yeah this isnít a step we picture too often as itís not one of the more glamorous. Youíre right that the mahogany dowel will be covered by the heel cap.

In the final shot, the neck is facing head down toward the ground. Iím using a dremel to rout away less than 1/16Ē of relief from the center of the neck heel. Because the body is curved at the joint and the heel is flat, they donít mate particularly well. Like |( . But if we if we take out some material, it joins up better. Like (( .

Hope this helps.

Excellent use of punctuation marks for demonstration purposes. As a moderator I would like to give you some prize for that, but alas we have none!

nacluth 09-05-2018 03:59 PM

More work tumbling out of our shop. This time some nice inlay prep. Even though we tried to talk Stan into something easy, he said he wanted beauty, so weíre giving it to him. ;) Hereís a shot of Steve working some magic on some curly mahogany.

https://s19.postimg.cc/kfxniut43/DDB...95_D9121_A.jpg


And then laying it out on the peghead...

https://s19.postimg.cc/x7btpcv6b/74_...C58_F39_C0.jpg


Of course, you need something to match on the fretboard. How about curly mahogany diamonds and squares?

https://s19.postimg.cc/7ojhccr1v/D33..._B45_C4871.jpg


And some other inconsequential work like fitting the bridge to the body.

Thanks!
