Re: More mandolin thoughts - the end result

Thanks for the image Peter. It does look like a lot of bracing for a small top but I know nothing about mandolins - though I am planning to try one soon so your work is going to be useful. Dave

Re: More mandolin thoughts - the end result

Peter that is good stuff. Have you come across any commercial mandolins with these characteristics? It is certainly a very handsome looking instrument. Making and selling 7 mandolins plus the eighth since you last wrote means you really have been busy! When you say braced like a guitar it sounds lik...

Re: straight dovetail

As one can see from Alan's reply there lots of ways to do this joint. I would however point out what G&G say in the book, that any sort of dovetail is quite hard to adjust for the angle, up and down and side by side required to get the neck geometry right. A straight mortice and tenon makes these ad...

Re: Classical Guitar Tuners Creaking and Binding Up

Since I was fitting some tuners today I thought I might continue this a little. When I was making furniture I used to make my own dowel jigs (a la Krenov) and making them in a suitable hardwood such as oak seemed good enough. Exact spacing was not important since one simply reversed the jig to drill...

Re: Falcate Classical #2 Build (in NZ)

My falcate classicals were much too stiff. I have rather dodged it and gone to a traditional fan braced system but clearly it can be done successfully. We will enjoy following your experience. Dave

Re: Tornavoz

This is a bit woolly but I remember a thread on the Delcamp forum some time back about tornovozes and my impression was that they really didn't do much that was useful to the sound. I remember Alan Caruth who is a very reliable source discussing what exactly a tornovoz does. It could be worth your w...

I have a nephew who needs a SS repair in Melborne - not an expensive guitar - but is having trouble finding one within reach due to the lockdown.

Anybody know of someone near Fitzroy North?

Re: Moving Equipment

I remember when I bought my Jet sander (which I think is the equivalent machine) it came with two blocks of wood as spacers which I carefully stored. But of course I can't now for the life of me remember where they were used! I would just add that if the people you are employing are ordinary furnitu...

I am still using the simple bolt on joint - really just avoiding the accuracy issues of the full monty

Re: Classical Guitar Tuners Creaking and Binding Up

As Martin says it is often that the holes are a bit tight on the rollers, but also if the spacing between rollers isn't quite right (and there will be a tolerance on the manufacture of the tuners) then that will give you grief. A careful examination of the rollers as you insert them into the holes m...

Re: Guitar bridge as a brace

Adding another question to this. I had got used to making short bridges for my classicals - around 150 rather than the more traditional 190 mm or so. However I have moved to fan bracing based on Torres' SE114 and the short bridge did not intersect the last but one fan braces. I really wasn't sure if...

Sanding Sealer

In a continual effort to try to improve my nitro spraying technique (it's really not going that well) I went through Robbie O'Briens video course recently. He suggests a fairly serious sander sealer coat before using the finishing clear coat. Indeed he seems to ladle it on with a spoon! He aims to h...

Re: Still not getting the sound I want...help!!

There is a slight ambiguity in section 6.2.

Without wishing to state the obvious... There are the three tests required - long, cross, and twist. But for each one you do the usual ten taps, filling the ten buffers in VA which then averages the result.

You've probably already sussed this.

Re: Still not getting the sound I want...help!!

In terms of tapping, it is worth checking you have done the setup correctly as per the book. Such things as the FFt size and the number of buffers in the spectrum capture tab. It takes a bit of practice to get the ten taps timed right. You can see each buffer appearing as a block of colour in the ca...
