Re: 'Milling' with a drill press

I have seen a small combination lathe/milling machine/drill press on a Facebook ad, made in China for under $400. If I was flash.... ($400 is luthier wood or food to me). There may be an Aussie importer of similar machines, possibly worth checking out for build quality...? I have a safety planer, an...

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! The guitar is an L-OO design with forward shifted bracing and two finger braces, instead of one as per...

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...

Violins

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: Classical Build (s) - Hopefully falcate!

That's my favorite way to bind a fingerboard, just a fine line of maple or whatever. Simple and clean! Hope the rest of the build is proceeding well! Cheers, Ross

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...

Alternative use for stainless steel clothes pegs

The stainless steel clothes pegs here in the photo are useful for liners if they are modified with a kink in the right spot so that they exert an even pressure for clamping. I just used them upside down ie using the spring pressure to apply an outward force in order to narrow a truss rod channel wit...

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...

Re: 00 Acoustic build thread.

I have built a few OM guitars and a couple of Loo's with 25ft top and 12ft back. They sound nice with strong mids and a tight bass. However, I have had comments from a couple of luthiers who say that the more arched soundboards loose a little sustain? I haven't tried other arching so I wouldn't know...
