Gerber guitars - a few new builds to share
It's hard to believe that we are already half way through 2018. I haven't posted anything this year, so I thought it was a good time to share a little bit of what I'm working on. I'm currently working on a batch of three guitars for The North American Guitar. Actually it was a batch of four, but the first guitar of the four was a direct commission and it's already completed and ready for finish. And it's a replica of a guitar that I posted here on my last thread and I don't want to bore with a repeat.
All three guitars will be RL15.5 models, with Swiss moon spruce soundboards and a cutaway. For back and sides, one will be Honduran mahogany with beeswing figure, one will be figured Koa, and the last will be curly American Walnut. IMG_5190 by ryan gerber, on Flickr [IMG]IMG_5191 by ryan gerber, on Flickr[/IMG] [IMG]IMG_5189 by ryan gerber, on Flickr[/IMG] I've been working on these guitars for a few weeks now. Here are a few pics of the process of getting the rims together. Gluing the odd shaped neck block to the sides. [IMG]IMG_5323 by ryan gerber, on Flickr[/IMG] The initial shaping of the backside of the rim. I use a motorized sanding dish to put the 15' dome on the back, but I think this saves me a little time to cut close to the final shape with the router. [IMG]IMG_5315 by ryan gerber, on Flickr[/IMG] Shaping the bottom foot of the neck block. (neck block inspired by one of my favorite guitar makers, Burton Legeyt. He was one of the first builders for me to follow, and his neck block was an idea that I latched onto pretty quickly. I like the extra support in all directions). [IMG]IMG_5325 by ryan gerber, on Flickr[/IMG] [IMG]IMG_5327 by ryan gerber, on Flickr[/IMG] Applying the seal coat of shellac. Sorry, no secret sauce here, just the hardware variety of brush on shellac. I like to wipe it away with a paper towel right after brushing it on to leave a nice thin even layer with no runs or shinny parts. [IMG]IMG_5330 by ryan gerber, on Flickr[/IMG] The completed rim. [IMG]IMG_5335 by ryan gerber, on Flickr[/IMG] Three rims ready for backs. The sides of my guitars are laminated with three layers of .050" material. I use Spanish cedar for the inner two layers, which allows for a very good stiffness to weight ratio. The epoxy bleeding through the sides shows how porous the different woods are. Apparently the mahogany leaks like a sieve. This certainly makes pore filling a bit easier when it comes to that point in the finish process. [IMG]IMG_5333 by ryan gerber, on Flickr[/IMG] I'm a bit further along in the process but I'll stop here for now. Also, breakfast is ready!

Everything looks great. Very clean work for sure! All 3 are going to be beautiful.

Do you use Spanish cedar for the blocks and the linings as well? The interior of the guitar is so pretty that it's a shame you have to cover it up!

The linings are three laminations of Spanish cedar, the neck block is a combination of mahogany and Spanish cedar, and the back braces are mahogany. I like to keep it clean and simple on the inside....most of the time anyways (:

The backs of all three guitars are now joined to the rims, and I've started the rosettes.
Here is the rosette for the mahogany guitar, pre installation in the top. The red ring is amboyna burl, thicker lines are mahogany and walnut, and the darker pieces with really fine lines are made from super thin sheets of paper.

Thanks everyone for the compliments on the rosettes so far. I definitely find joy in making a rosette. It's a fun challenge to make something interesting out of that small little curved space.
Here is the third rosette, which will belong to the Walnut guitar. Towards the end, finishing up the inside purfling lines. [IMG]IMG_5377 by ryan gerber, on Flickr[/IMG] And the finished product minus the most inner ring, which will be installed after the soundboard is brought to it's final thickness. I've done this design a handful of times over the last couple of years, and I'm always trying to make small refinements. In this one, I've stuck with only one species of wood for the mosaic pieces, which I think I like better than the times that I've used an assortment of species.

Ok, now you are just showing off. That last Rosette is phenomenal!!! How do you do that? Amazing.

Ha! I guess that means it's a success! Joking aside I'm glad you like the rosette. The curved tile pieces do add a little difficulty compared to straight lined tiles, but if you put them together in the right order it's not that bad. Working with darker woods also helps. The hardest part in this rosette are the two little pieces off by themselves in the bottom left. Getting the light colored purfling lines tight agains the maple ring takes some patience. If they aren't tight the glue joint can show really badly.

I figure since Bruce has a thread going with his new apprentice, I would share mine (: Not very many days pass by without my 6 year old daughter asking me if she can watch what I'm doing while I work. She loves to vacuum the shop, adjust my light so I can see better, use the spokeshave, and recently she's moved on the the file and rasp drawer.
I love building guitars, and I don't take for granted that I get to do it everyday. Equally, I love that I get to be at home with the kids and be an active part in what they learn and how they learn. Most days anyways (: [IMG]BD4A1549 by ryan gerber, on Flickr[/IMG] [IMG]BD4A1544 by ryan gerber, on Flickr[/IMG] As for the progress of the guitars, I'm working towards getting all three tops braced and ready for joining to the body. I hope to finish that process today, and then start working on the bodies this week. My simple setup for testing the deflection of soundboards and backs. [IMG]IMG_5393 by ryan gerber, on Flickr[/IMG] For anyone wondering about this chisel, it's an incannel patternmakers chisel and it's my absolute favorite for shaping braces. The curved geometry gives a few advantages. It naturally hollows out more of the side of the brace, which takes a few extra grams off the weight of the top, without radically changing the stiffness of the braces. It also is less prone to tearing out when you hit a section of grain runout. And I love the bent neck handle. It keeps your hand further away from the cutting surface and gives you a better angle of approach. Does anyone else out there use these chisels for brace carving? [IMG]IMG_5396 by ryan gerber, on Flickr[/IMG] My shop tends to stay pretty cool in the summer because it's in the basement and the heat lamp helps a lot with using hide glue.
