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.

Small guitar
Here is my latest guitar. Not many guitars this year (only 2), mostly mandolins or tenor guitars. This one is a small bodied guitar, short scale length (23.5inches) made mostly from native woods as per the customer's request. Top is King Billy Pine, back and sides Otway Blackwood, neck Blackwood, ro...

Re: Guitar Cases
Resurrection of an old thread. Presto Cases has closed down, so they are no longer an option. The last Cedar Creek case cost me around $1800 and nowadays would be well over $2000, so not really an option anymore unless desperate and the customer is prepared to pay. I did find a quite nice carbon fir...

Re: Mandolin in Engelmann Spruce and RIver Oak (redux)
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 ...

Re: **** Stewmac special on European Spruce *****
Mine arrived on Friday. I have to agree with Martin, the grading is optimistic, but the tops are certainly usable. For the money and free postage I paid a fair price so am not complaining.

I have used Pack and Send before several times, but they don't have a local office (nearest is Canberra) and the local couriers they use are hopeless.

I agree with you Allen, and have done what you suggested before, but in this case the mandolin was worth nearly double the threshold and I was not willing to take the risk. This is a particularly difficult shipment because not only is there the crap I have to deal with, but the customer has to deal ...

Re: Falcate Braced Guitar No CF
My thoughts are that not using carbon fiber means the braces need to be bigger and hence heavier so the top will be heavier. The top itself also may need to be thicker and hence heavier so overall you won't get the maximum benefit from falcate bracing. As for the argument about carbon fiber on the t...

Re: Carbon fiber Nut n saddle
I am with Steve on this. The reason to use carbon fiber is because of it's very high stiffness to weight ratio. The is no advantage of a high stiffness to weight ratio material for a nut or a saddle, and bearing in mind the disadvantages, there is no good reason to use it.

Re: Carbon fiber Nut n saddle
I use a carbon fiber rod (1/4 x 1/2inch) as neck reinforcement on all my mandolins instead of a truss rod. Works great. I would never use carbon fiber composite for a nut. It would be the quickest way to wreck all your nut files, so if you want to keep Stew Mac in business go right ahead. Should wor...
