Re: Considerations please for violin making manual.

Dominic, most, if not all, of The Strad posters have enough information to make moulds and templates. Roy Courtnall sells a plan for what is probably a generic Stradivari, ( I think it is based on what is used for Newark students), but if you want to build an instrument based on an actual Stradivari...

Re: Considerations please for violin making manual.

I second Martin's recommendation. I have the Johnson Courtnall book, and it's widely regarded as the best available. Have a look at Michael Darnton's website. He is a U.S. maker who is working on a book at the moment, and if I remember correctly, a fair bit of his material is on his website. He has ...

Re: Tassie tone wood suppliers.

If I remember correctly, their advertisement in the last issue of Australian Wood Review (the back cover), featured a lovely blackwood uke by Jeremy Fullerton, one that I thi...

Re: My source for Walnut Oil

Martin, I find your preference for walnut oil very interesting.I have often wondered why olive oil is so commonly, and successfully, used in French polishing, rather than walnut oil. Olive oil is, I believe, not a siccative (i.e. drying) oil, whereas walnut oil is, as long as there are no additives ...

Re: Small volume epoxy technique

I have always used scales capable of weighing to 0.1 gramme. It gives a very accurate measure for small quantities. For example, I use a small disposable plastic cup, weigh it, say 4 grammes, add 10 grammes resin and 2 grammes hardener and if it all now weighs 16 grammes, I'm spot on.

This is a very useful programme for generating curtate cycloids. It's called CCycloid, and is designed for stringed instrument makers.

Re: Blackwood Style 1 Weissenborn copy

Alastair, the one you listed as #120 is, I believe the 4F grade, but confirm it with them. I don't know how it compares to the Behlen pumice from Lee Valley that Martin is suggesting, which I'm sure is very good. Behlen products are certainly reliable, but the stuff I got from Shell-Lap worked well....

Re: How to determine runout in spruce top billets

Thanks Markus for doing this. Since, as you have demonstrated, silking and runout can cohabit the same piece of wood, we clearly cannot take the presence of silking to indicate the absence of runout. I wonder if Rudy Fuchs is aware of what the English version of his website is saying? This is a very...

Re: How to determine runout in spruce top billets

I was just having a look at Rudolf Fuchs website ( http://www.germanspruce.com ) where he says that " a nice cross silk pattern reveals that the wood has been accurately split (no run out) and quarter sawn. Is pronounced silking generally regarded as a reliable indicator of little or no runout?

Re: Archtop Ebony Tailpiece

The dimensions of the tailpiece are given on the Benedetto plan. The thickness is 5/16" (very close to 8mm), and the fulcrum extends 3/16" , so the overall thickness is 1/2'' measured at the fulcrum. As Rod says, the fulcrum is a separate piece inlayed into a shallow trench.

I may be misunderstanding the problem, but it is not the back (i.e the face that will form the interior of the violin)that you should be worrying about at this stage, unless it is warped. If it is warped, you only need to plane off enough so that it sits on a flat surface without rocking. Flatten th...
