Re: Introductions - a polite request

Hi Geoff, Did you build the resonator from scratch? What plan did you use? A resonator is on my "wish list" Thanks, Scott C. Hi Folks, newbie here. The name's Geoff and I'm from Canberra. I will be retiring in a few weeks and would like to build a few more guitars as retirement projects. With John C...

Re: 1st try to visualise vibration modes

Thanks, I'll try the tapping tomorrow. Scott C. Thanks, would a back with only 3 ladder braces live? Impossible to say without knowing Young's modulus for the back, its thickness; height and width of the bracing and their Young's moduli, how they're shaped etc..

1st try to visualise vibration modes

Well I gave it my first try with my A. Picado classical guitar. 1. I had a hard time pinning down the exact frequency. 2. T1 came in at 97-98Hz 3. T2 came in at 197-199Hz 4. T3 came in at 230Hz when measured back side up, I could really hear it resonate when it hit 230Hz, top up it was not clear. Is...

Re: Resonator

Hey Nick, I have a couple in line before the resonator as well. I priced all the premade metal parts at about $220 USD. I won't be building from a kit either Scott, there's enough info on the drawings to be able to knock one of these up. I will be buying in pre-made a soundwell though, be bloody har...

Thanks a bunch, I do want to build from scratch rather than a kit. It looks like I should be able to do it! Scott C. could I really build one from scratch with those plans? From memory (I've had them tucked away for a while now waiting to make a start on the reso) the answer is yes. They're 1:1 and ...

Speaker

Hi Trevor, I just got my speaker and amp and will be using Visual Analizer as my tone generator. In the design book page AI-4 Fig AI 2-1 it states the speaker is loaded in a piece of PVC and capped on the far end, my questions are: 1. How is the speaker mounted in the PVC? 2. Is the cap on the end o...

Re: Free tone generator software

I was thinking I needed 0.1 resolution from a tone generator, but now I wonder if that is necessary for accurate modal tuning? Ah, OK. Visual Analyser (wave tab) will do down to 0.01Hz increments, but you have to type the numbers in. Just tried it and it seemed to be working, though it's pretty har...

Free tone generator software

Hi, does anyone know of a free tone generator software for PC that will generate the tone to the 0.1 Hz frequency? I found several that do not go into the 0.01 Hz division.

Re: Mahogany Back

Thanks, It feels pretty rigid, I'll double check everything. Scott C. Sounds real thick to me, too. If the numbers are right, you'd probably be able to feel that the wood was comparatively floppy. As usual, check everything. If it still seems sus, try a different method and see if you come up with t...

Mahogany Back

Hello, I am making 2 steel string J45 Dreadnoughts using mahogany backs. Using the tapping method and formulae, I came up with 3.5 on one back and 3.75 on another, does this sound close to any you guys have done? I know all pieces are different, but this seemed a little thick, but it could be that t...
