Started my Multi-scale triple O today.
Basic's:
Western Red Cedar top plate
Cherry back and sides
Tulipwood laminations to the sides
Mahogany neck (bolt-on)
Rosewood fretboard
Other details to follow.
Thickness' the Cherry sides and the Tulipwood full width laminations with the intention of getting the sides laminated and fitted to the end blocks before starting the front and back plates.
One cherry side bent and linings currently cooling down in the bender. I'll look to assemble this side and laminations before bending the second side and it's laminations (second side has a cutaway).

These builds are coming thick and fast now, aren't they? Keep the pace up; it'll give me a chance to take a breather from mine perhaps! I look forward to reading about your adventure as ever!

Looking forward to seeing the build progressing Francis. Hope the 'guitars for sale' re-appear after the house move  . |

I'm interested in the scale lengths you decided on (and the logic behind them).
I've recently been through the process of trying to determine the optimum lengths myself, for a commissioned build.

Making up a clamping caul for the laminated sides from 5 layers of thin (circa 1/16") plywood. I've used 3 layers between the caul and the body former to approximate the side/lamination thickness and pulled the caul to shape with a mix of heavy spring and screw clamps with a standard PVA white glue between the layers.

Francis Thanks for the link to the design thread. I must have missed that. It's a bit late, but I found this site useful for visualising the different fan fret possibilities: www.ekips.org/tools/guitar/fretfind2d/and the guy building my guitar used the tables it generates to prepare his fret slotting. I wimped out at the scale length spread and chose 20mm: I saw several comments online that suggested that anything under 25mm is comfortable for most people, and anything over is 'noticeable'. The long scale is 660mm (both of my existing guitars are 650mm, and comfortable with .13-.56 strings). The eighth fret is the 'normal' one. All of this is very conservative, but then I've never actually played a fan fret guitar, so there is a bit of adventure here. Good luck with your build and I'll follow with interest. Kym |

Francis,

Francis, I'm not seeing any pictures. Should I be? Not yet this bit is quite boring - layers of wood covered in clamps.... |

Haven't quite got a picture of what you're doing but doesn't white pva have a reputation for creeping if it's under stress? |

Francis, I'm not seeing any pictures. Should I be? I must keep Dave happy as I gleen so much from his contributions to this forum...  Glue-up time!   I think you should be able to make out the plywood inner caul. The knobbly bits on the outside of the former are there to wrap a bungee cord round. That's virtually all my smaller spring clamps.

Have you noticed, by the way, that nobody on the planet has worked out how to remove the strange numbered labels from these spring clamps? I've never seen a bare one.
