Ears

I thought I'd start a thread on how we luthiers perceive tone, texture and musical performance using our ears. I have found that ears have a limited short term memory! The ears tire easily as well when listening in the usual acoustic circumstances which require "fresh ears". That's why many famous a...

Heel grain orientation

I have made a few necks from walnut wood lately. The wood tends to split along the grain easily, and so I'm reviewing my understanding of heel grain orientation. Comments please. Cheers! Ross

Re: Truss rod bulk buy

When you talk about different threads on a truss rod, are we talking pitch, ie the pitch of each nut's thread on the two ends of the rod?

Finish thickness

I read this idea on another forum. The luthier had used a balloon and a piece of plastic inside the soundhole when spraying, in his case a piece cut from the bottom of a milk container (not sure if the same kind exists in Aus, be creative). After spraying, he peeled the lacquer off the polyethelene ...

Re: Qualities of Spruce

Wouldn't end grain structural assessment using a low magnification pocket microscope be a good way to identify the different species? Or do all the spuces exhibit a similar end grain structure?

Of course working out the Young's modulus would be the next step for builders.

Crystalac

I'm wondering if anybody has used Crystalac Brite Tone for their acoustic instruments? How does it perform? Does it damp the sound? Can it be applied in small ares over old Crystalac for finish repairs?

High frequencies

I have made a guitar using an Italian Alpine spruce soundboard. Previously, I have used my stack of Sitka for my steel string guitars. I may be guilty of changing too many variables simultaneously!

Re: Violins

Graham McDonald: I have long been a fan of the late Henry Strobel's book on violin making. Simple and step by step. For what it is worth he suggests the top resonance should be around F#, which I have found works well. The other important factor is the weight of the plates. H S Wake's violin buildin...

I have been mucking around with an old Chinese or Japanese made violin having removed the "plates", which are by all information I can glean from the internet, too heavy. The resonances are also pretty high. The information on Dr Google is contradictory-there seem to be many theories! Has anyone use...

Re: New Luthier Tips du Jour video-What is torrefied wood?

Very interesting and informative...Water has weight, so soundboards which remain dry and don't react to humidity variations as much would be lighter? Also, it is feasible that a torrefied guitar has less movement in it for the same reason and can therefore be built to finer tolerances. I have read t...

Re: Wood Waste

The amount of wood waste that a luthier produces is not that much when compared to a factory making Chinese cheapo guitars. I have wood heating at home and a lot of the wood goes into that. I also make firelighters out of the sawdust and chips collected in my dust extraction system. An egg carton fu...
