That one seems to be fixed. Well done! 8) I hadn't looked up which data (cells) you run through the formula. A very common mistake to use a wrong cell though, a simple typo I guess. The idea to use ^0.5 instead of sqrt came because I remember having gotten strange results with Excel's SQRT function...

Thanks for the help, taking the time to run the numbers. It turned out I was using Gpa instead of Pascals for Glc. ((0.95977*C13*(C14^2)*SQRT(C5))/SQRT(E8+((C14/C15)^4*E9)+((C14/C15)^2*((0.02857*E8)+(1.12* F10 )))))*1000 When I did the partial products for the denominator I noticed a product too sma...

Thanks, I tried (xyx)^.5 and I tried separate calculations for all of the products in the denominator.
I think a calculator will be my next go.

Thank you, for the check. Not too late at all. I will go back and re-code equation Equ. 4.5-7. it really help knowing that density, El, Ec and Glc are exactly the same to isolate the problem. I did go over the equation again and it looks correct as far as I can see. Here is the equation I have that ...

I think we were hoping that it would save space, if it was any good.

I thought the same thing! That is why I now have both an Earlex and a compressor\sprayer setup. I still use my Earlex around the house.

I have been working my way up toward the more interesting aspects of this guitar. Building jigs and forms is not my favorite thing and if there are templates, bending forms and molds available I will happy give the fine people who make them my business. Like the harp ukulele I made I am in the situa...

You mean there is a better way to fix a bridge??

Back and Sides East Indian Rosewood Sitka Spruce Curly Maple Bindings Walnut Rosette Ring Brazilian Rosewood Fret board, Head stock veneer, and Bridge. Finish Zpoxy pore file on the back, sides, rosette ring and head stock veneer, Shellac wash on entire guitar (except bridge). Em6000 sprayed finish....

I have a HV5000, one can buy different needles for it. It does not have a spray pattern or size adjustment. I found it did an OK job, but ultimately I got a QS-125WB and a compressor and have been much happier.

I am with Allen, my zero fret is right at the break and I slant the bottom of the nut.

Thanks guys, I have and I do make long radiused sanding blocks. Luckily my wife has a large format printer, so it is easy for to make arcs in a CAD program and print them as a guide. I like the dishes to serve as my work board during the project. I also leave the braced top and back pressed into the...

Looking good! I have used a couple of different versions of that jigs for routing the mortise. One with templates sized for a guide bushings the other template requiring a pattern following bit. I have had issues with both so there is a bit of give and take. I like the guide bushing because I can ma...

I made some progress of my bending forms. I decided to also make a cutaway form. I have a cutaway clamp on my fox style bender. I need to get some pipes to finish them off. I also need to wait for my 10 foot radish dish of that I can profiles the sides. http://www.harvestmoonguitars.com/Gore_SS/gore...

I think it will be awhile before I do the interesting work as I am working on jigs and forms. The 3 meter radius dish is throwing me for a loop, but I will find someone to make. I will probably have them make a 10 foot dish so that it is understandable. I have a 32 foot dish, so if no one complains ...

The Design book say that 2.8 just about assures a non active back. This wood is less dense than IER by quite a bit so I suspect the above plate could be a bit thicker as the mass would still be lower than a typical rosewood plate to achieve the same vibrational stiffness.

Thanks Martin, I am not sure why there is the small difference, maybe the way I entered the formulas into excel. Here are the thickness calculations I got for the back. I really had to thin the plate to get all of the saw marks; I ended up right at 3 mm for the tap test. The thickness basically came...

I thought this might best forum to start and maintain a build thread for a Gore medium body steel string to his plan form the Build book. I will try to follow the proceedure as best I can from the book, although I can not promise I will do things in the same order, but I will at least follow the dep...

Thank you,

I think the stuff I ordered will be close. I am just starting a project building the falcate braced SS you have in your build book. A bunch of new jigs and templates to make and new experiences. I am looking forward to it.

... The fibre is 3k tow, 198 gram/1000m, which is what it says in the book. ... In the states I am finding a product: Weight: 5.7osy, Weave: Plain Tow Size: 3K, Thickness: .010" which I think is very close to the above listed fiber. I am a bit confused about the gram/1000m (Tex) called out in the b...

I finally was able to jump in on a new guitar, and start following the methods laid out in the design and build books. I took the 7 measurements before gluing up some nice sound WRC, and processed the numbers through an excel spreadsheet. When all was said and done I did end up with numbers that wer...
