Australian/New Zealand Luthiers Forum

I was born and raised in Christchurch....the place is cold and damp because it's built on a swamp. I solved my
humidity problems by moving to Adelaide

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.

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...

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...

Nice work mate. I fixed up that photo that was on it's side....makes it easier to see that nice stash of wood behind the guitar

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...

A week to get stuff from the US to Australia.....while good old Aussie Post takes a couple of weeks to get stuff across the country. I am also into my second year of this. Pays for itself quickly, but the free shipping is slow, very slow now. I do the flat rate expedited option for ~$30 on every ord...

I think Nick Oliver has built a few. He's not active at present but a PM may get a response. There are quite a few threads on the subject of Selmer Maccaferri guitars....here's one to get you started viewtopic.php?f=1&t=7344&p=80738&hilit= ... rri#p80738

Exact action setting will depend on a few factors including personal choice but here's a rough guide. Trevor has some figures in his books...my copies re stashed away at present so cant access them. https://www.stewmac.com/video-and-ideas/online-resources/neck-building-and-repair-and-setup/metric-st...

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 prefer less eloquent language...luthery is the art of covering up your stuff ups!!

I have found that an important part of this game is the ability to recover from an error or unanticipated outcome.

Nice work Richard....classy looking guitars.

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 ...

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.

Okay good to hear.

Hello
I have now adjusted my excel sheet to match the formula for thickness and I am getting the same result as the screenshot so I cannot hunk I am good to go

Sorry David...have been very busy with a new house build so havent had chance to send you that spreadsheet. Will get onto it tomorrow.

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...

We generally prefer an introduction and hearing a little bit about yourself in a first post. Perhaps if you could post up a brief intro we might be more amenable to hearing the name of the company that supplied your belts.....assuming of course that you don't work for them :) I know this is an old t...

Give me a couple of days...busy painting a new house right now. Martin that’s a good one! Ca.n You complete the circle now and send it on??? !! I only had a screenshot so must be something wrong With the way the formulae were done.... We are in lockdown here and a perfect time for me to try the TG m...

Hello
I definitely took it as a screenshot from the forum and then got someone from my job to do up a spreadsheet taking the formulae from the book. The sheet was titled 013 Classical

LOL..yeah definitely one of my spreadsheets. The title refers to one of my engleman top sets

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.

Hi David, As far as I can ascertain the forum software isn't set up for Excel attachments...jeremy and I are looking at this. Re spreadsheet results...first thing to check is units and in particular number of zeros in same. Re tap tests. VA has a facility to average tap results over a selected numbe...

Chladni patterns are useful for visualizing how much of your soundboard is active and also for identifying/confirming resonant peaks. Get VA up and running and get familiar with tap testing before getting geared up for Chladni work. Thanks for that I was just trying to get used to the whole TG metho...

My result was 2.9 degrees but my Taylor was 1.3 so hopefully I got that bit right.

Rather than using that Taylor as your guide I'd be using the information in Trevor's books as your guide......you may surprise yourself and end up making a guitar that sounds better than your Taylor
