Re: CNC Fretboard

I have a CNC, but have never used it to cut fret slots. The reason why is that it is very slow and as you already said the small bits you need to use tend to break. It makes much more sense to cut a template on the CNC and use the template on the table saw to cut the slots. I can cut slots on a fret...

Re: Domain name issues

Yes, I came to the same conclusion. I got an application form from the Chinese domain registry but replied telling him I can't buy them all, and since I don't have any Chinese customers and am not targeting China forget it. If I was trying to sell in China that would be another matter.

Re: Mirotone demise and WB lacquer

I use Target Coatings EM2000 which is a water based oil varnish emulsion. I brush it on, but you can spray it. Have been using it in it's various guises for at least 20 years. It is an American product, I have not found anything equivalent locally, so is difficult and expensive to import. However, i...

Only high level domains are done by an international body. Lower level domain names are done by organizations in the individual countries' domain.

Re: Carbon Fibre Threads

I will butt in here since I have been using carbon fiber in my flat top mandolins for a while now. In the mandolin world there has been even more misunderstandings about carbon fiber. This is all covered in the Gore/Gilet book but bears repeating here. The advantage of Carbon fiber composite is resi...

Re: Mandolin bracing. Help needed

On archtop mandolins they are all X braced. On F soundhole mandolins, the arms of the X are closer together, and the X crosses further foreward.

Re: Mandolin bracing. Help needed

Well Mark it is your mandolin, you can do whatever you like with it. It is true that mandolins are quite different from guitars. The string pulling force is greater than a steel string guitar and the forces on the top are different. With a floating bridge, there is no rotation force on the bridge, j...

Re: Mandolin bracing. Help needed

Yep, 3 transverse braces, but the brace under the bridge does not go right across the top, it effectively takes the place of the bridge in a classical guitar. It is not notched, although you can notch it if you want to make it neater and waste some time. With CF on the top notching is not necessary....

Re: Mandolin bracing. Help needed

I have repaired a collapsed top before on a vintage flat top mandolin by removing the back. A brace had come loose from a previous repair because the repairer had not tucked the end into the linings. I used steam to remove the sag and re-braced, tucking the bracing into the linings. As far as I know...

Re: Vale Frank Ford - luthier and teacher

I visited Frank Ford when we travelled to the USA in 1999, and had a good look around the shop. I left one of my mandolins with him and they sold it shortly afterwards. Frank was very generous with his knowledge and many of us benefited, including me. He will be missed.

This one is a small bodied guitar, short scale length (23.5inches) made mostly from native woods as per the customer's request.

Resurrection of an old thread. Presto Cases has closed down, so they are no longer an option.

I use bridges made by Vern Brekke. Mandolin, mandola and Octave mandolin, carved top or flat top. They are adjustable but don't use thumb wheels and are adjustable via two allen screws that move two wedges in or out. Very neat design, and Vern can make them to your specifications in terms of bridge ...
