Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Build thread for first Gore SS from the plans in the boo
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.

Re: Build thread for first Gore SS from the plans in the boo
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 ...

Re: Earlex spray unit
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.Peter Young wrote:Thanks everyone for the comments.
I think we were hoping that it would save space, if it was any good.

Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Earlex spray unit
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.

Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Classical No 13
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...

Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Build thread for first Gore SS from the plans in the boo
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 ...

Re: Build thread for first Gore SS from the plans in the boo
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.

Re: Build thread for first Gore SS from the plans in the boo
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...

Re: Carbon Fibre
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.

I finally was able to jump in on a new guitar, and start following the methods laid out in the design and build books.
