Would someone be so kind as to post some "ideal" target resonances for the Uke family? Cheers! Ross

Removing old shellac?

In a recent post one of the members said that they had applied some tinted shellac to a soundboard, then decided that it looked bad and removed the shellac. I have been working on a guitar and have done exactly the same thing, deciding to remove the shellac. However, I have found that it clogs sandp...

Re: Maple or Sycamore for purfling

An interesting subject. I have used plane tree timber for bindings with walnut successfully. It has a similar figure to Aus Silky Oak, (in the US Silky Oak known as 'Lacewood"). But I have found that it doesn't scrape well, when compared to Plane , Blackwood or Maple, which I have also used. Persona...

I admit that I don't wear the gloves much, and don't pull any punches or throw any fights! :mrgreen: The gloves however, do sit near the bending iron and are deployed when I need them to get close to the heat. Mainly on sides actually. They are also good for the bindings, depending on the wood. I al...

Steve-maybe there are traces of some kind of mold release left which is preventing the bonding to the CF if that's what it is...

Test a small patch to see if epoxy sticks to it. Remember that the function of the bridge plate is primarily to prevent the bridge pins ...

Sounds like you got the bug, brother! Or will soon have it! So buy good tools, one step at a time as you build. One can always sell good tools and pick good ones up second hand, if they have not been worn out by tradies! Go for home handymen who have moved on for 2nd hand is my opinion. I have never...

Personally, I'd prefer a rephrasing of the admin post so that lurkers can comment how m...

Hey Trent...also beware of built in obsolescence with computers and software. The zoom suggestion is all you need really, as long as you can record from it to the computer.

Re: Home/workshop recording studio setup help

A dry sound is best for a guitar when simply recording its qualities. The term "dry" here r...

I forgot to mention above that arching a soundboard effects sustain, top resonance and projection. Confused? So am I. That is why, as well as knowing a bit of "left brain" luthierie, experience is also important, and so is tradition. Look at violins...they evolved over generations on a largely exper...
