Re: Classical Guitar Tuners Creaking and Binding Up

When drilling use a brad point bit...more chance of the bit staying centered when you start the hole.

Re: Building Conditions

I was born and raised in Christchurch....the place is cold and damp because it's built on a swamp. I solved my

Re: Classical Guitar Tuners Creaking and Binding Up

Possibly rollers binding up in the holes. Try running a reamer through the roller holes...or a piece of dowel with sand paper wrapped around.

Re: Anyone able to have a quick check here???

If 180Hz is your target for T(1,1)2 then I'd start by making up your bridge and weighing it. This will give you a better idea of how much drop in T(1,1)2 to expect once the bridge is on. If it was me I probably wouldn't thin the periphery of the lower bout at this stage. I'd get the bridge on and th...

Re: Long time no build

Might as well add to this thread. My workshop has been packed up for close to 3 years now while I build a new house. The house is nearly finished and I should be moving in mid October. The garage and workshop have been home during the build and once I'm back in the house there'll be a few months spe...

Re: Soundboard Sonic Signature

I've worked on Chladni patterns for the guitars which show that the responses for the 01 Classic guitar (great one) are not symmetrical at mid frequencies 400Hz - 500Hz, here the lower bout treble side is less active than the bass. I will today investigate if the same is true for the weak guitar, m...

Re: What dimension for bridge

Stick in a packer on top of 12th fret with thickness equal to final action heights for strings. Measure height of straight edge above top of bridge at saddle position and then see how much you have for bridge to top saddle height.

I agonize over this...so much so I always do a fullscale drawing of the guitar and carefully check all string runs etc. As an aside I can tell you that I faced a very similar problem recently. I made a falcate braced 7-string multiscale fan-fret thing. The placement of the braces and the bridge was ...

Re: Shed Building

Controlling the humidity is one of your biggest challenges. Good ventilation is the key. Containers are also all metal so they're a thermal bridging nightmare. Anywhere you have thermal bridging going on there is a risk of condensation...and mould. I'm in the middle of a Passivhaus house build where...

What Mark has said. Double check measurements and then if the bridge is still in same location get ready to take it off.

Re: Hybrid X lattice bracing

My immediate thoughts. How thin is that top? The braces look fairly meaty and my main worry would be ending up with an over braced lower bout. I bought Symogi's books and there are some interesting ideas in same but I've found Trevor Gore's books much better as he explains the theory behind the desi...

David did you code up that spreadsheet yourself or get it from another source? It looks suspiciously a lot like the sheet I coded up a couple of years back. If the latter is the case then the coding should be ok......I'd check your input data.

Chladni patterns are useful for visualizing how much of your soundboard is active and also for identifying/confirming resonant peaks.
