Post subject: | demo guitar build |
I needed something to occupy myself between customers (which there isn't very many of), and something to show potential customers for commissions, so I decided to make a demo guitar. I chose a OM style cutaway because I felt the smaller body and deeper waist allows for a better looking cutaway, and I wanted to try something other than a Dreadnaught anyways. unlike in the West sourcing birch plywood with high ply count is impossible. Sure I could order the stuff but since I needed a lot of them for making jigs, the cost tends to be very high. Instrument wood is no problem of course, because I don't need as much of them. I start with the neck blank since I needed to set the preliminary neck angle: I had a very dull bandsaw blade so the cut skewed by a fair bit, so I had to do a lot of planing to correct it. I've used hide glue for all construction, because I wanted to see how it would hold up. However I would still use titebond for things requiring more open time. I then leveled one side and the top of the neck blank. I had to make sure both of these faces are squared to each other, but in doing so I actually angled both faces a bit, although they are square to each other. Not wanting to order additional materials, I made my own kerfed lining. The heel/end block and the neck blank was prepared. Moving onto the plates, I had a set of rosewood back and side sitting around for a year or so, I also had a set of sitka top but the grain runout was horrible, something like over 30 degrees. Not only that, the grain was sort of wavy and the quarter was very off (also around 30 degrees), so after planing them to thickness, I realized it wouldn't make a good top and scrapped it, instead decided to use some of the nicer German Spruce top I just bought... I forgot to shoot photos of these step but I had been thicknessing the side, back, and top, and fingerboard. I made a backstrip by cutting out a 1/4" strip of a maple back material then laminating them with some maple and rosewood veneer. Like I said, I don't want to order additional material if possible... This is what the guitar will have: Body: OM cutaway style Top: AA Grade German Spruce top Back/Side: Indian Rosewood Fingerboard/Bridge: Gaboon Ebony Binding and trims: maple Rosette: still thinking, possibly a contrasting wood rosette. Neck: Khaya Mahogany |

thanks for the photos; nice to see the process in detail for those who have yet to build an acoustic. the black marker makes me cringe a bit, but i assume you don't use it anywhere near "final" wood |

I use them so that I don't make a mistake because I can't see the marking. |

Fingerboard planed and leveled Cutting off the bad portion and setting the nut position Slotting fingerboards, took a long time and arm was very sore. Finished slotting the fingerboard |

Finished thicknessing the back. It still have some tear outs from the plane, but it will be sanded out later. |

Nice guitar on the way! The bigger advantage of using a go-bar, is the easy access to clean the glue before it dries. You should take advantage of it. |

Guitar is ready for finishing (I plan on oiling the neck with Tru Oil, and french polish the body) |

Can you tell me what radius' you used, back and front,,,,did you use white glue for the whole box or hide glue on the top and back? Nice job,,,how much time did you have into it? Regards Joe |

Regards Joe I used hide glue for everything except for closing the box, neck and heel blocks, and fingerboards. In that case I used titebond I. Front and back radius is 25' but I am thinking of using a flatter radius for the top because I keep ending up with gap under the fingerboard that I don't quite know what to do about. The trouble is fitting a wedge under the fingerboard, I can't produce an exact fit without a lot more time just fitting one joint. I haven't counted the exact hour but I started in December and finished end of April. |
