  1. Take this for what it is worth: "HUMAN CONTROLLED SYSTEMS of SPL generation are an INTEGRATED system that stretches all the way from the skill/intentions of the player to the movement of the speaker cone in the room. A (hopefully) harmonious system that is inter-dependant (to varying degrees and often in a bewilderingly complicated series of relationships) ON EVERY SINGLE COMPONENT IN THE SYSTEM. Again. INTEGRATED SYSTEM, DEPENDANT TO VARYING DEGREES ON EVERY COMPONENT IN THE SYSTEM. EVERY SINGLE COMPONENT IN THE WHOLE SYSTEM MATTERS TO SOME DEGREE, IN SOME RESPECT. The pick matters. Dude. The FUCKING PICK MATTERS." It is no debate, just carefully and critically listen.
  2. Complete seat of the pants neck reinforcement engineering. The graphite is layered with strips of mahogany and sandwiched between strips of Formica. Each step of the lamination process I placed the bars in a clamp at the 22.5% point and listened to the sound when I set them in motion. These beams were quite lively and worked wonderfully in an 11 string electric alto guitar/ lute. I had misrouted the slots so it was a good time for something different. CA gel was used for laminating and installation.
  3. I'm trying to be helpful here because misusing and/or misunderstanding a term can lead one astray. Hardness is confused with stiffness quite often and understandably so. Steel is a great example. Moment Of Inertia and Modulus Of Elasticity of a material can be a helpful guide when designing or building a beam. A neck is a beam. Think about resonance and how the construction of a neck influences and causes changes in resonance. Look at how Warwick installs short bars at a strategic area on their necks. https://www.youtube.com/watch?v=ZZwjJSQB0z4 My problem with epoxy is it needs to be measured and mix properly for OPTIMAL results. I've also experienced glue softening and shear failure on 20 year old work. I use it only when CA is impractical. Use slow cure CA gel when gluing in graphite or Titanium neck reinforcements. YMMV.
  4. I'm curious why hardness is of a concern here when stiffness is more pertinent. As I posted in your Wood ID thread, MOE and MOI are what should be of concern. I would suggest Titanium reinforcement. https://asm.matweb.com/search/SpecificMaterial.asp?bassnum=MTP641
  5. Using different species for neck laminations will quickly reveal how they contribute to the tone of a guitar. A neck made of laminated mahogany will sound very different that one made of mahogany and maple, or purple heart or ebony or rosewood................ The benefit of laminating is an increase in stiffness and strength. Be aware that resonant frequencies will change with the number of laminations which can be to your advantage, or not. Check this link on neck woods: http://www.alembic.com/info/wood_neck.html
  6. Perhaps you mean stiffness since hardness is the measure of a material's resistance to surface deformation. MOE and MOI are more pertinent when dealing with a beam which is what a guitar neck is. MOE or Modulus Of Elasticity, is the ratio of stress to strain or the stiffness of the material of a structural member. More simply, the resistance to deformation. MOE generally refers to the overall stiffness. MOI or Moment Of Inertia is the bending stiffness of a structural member's cross sectional shape. MOI is specific to the cross section of a member. Remember that stiffness and strength are not the same. Build what you want with what you have.
  7. Just cut a few inches off of a test piece of wood and listen to what happen to the frequency from your initial test.
  8. Hold at a spot 22.4% of the total length of what you want to evaluate.
  9. Here's a basic version of a SCE (solid classical electric) in pine.
  10. I'm gonna necro post here for a bit of background that may useful. ( See the Ice-Stroyer thread. ) From the start this was about the original 21 fret Charvel Star guitars. I wanted a guitar in the spirit those guitars. I like the ESP Kami motif and the image I used was of a Kami model with a very square on front view. Weight, balance and hand position were very much in my thoughts. Two changes that made sense for me was to shift the neck to have a standard bolt-on 16th fret join and a thinner body thickness of 1.1875". This guitar is for Thrash Metal so the glory is in the MIDS. A maple neck, slim mahogany body and an OG Dimarzio X2-N guaranteed a good time. Original quick concept sketch to get my cuts figured out with the wood on hand. The pickup, and the bridge from my OG Schecter Dream Machine in situ.
  11. Getting a good square on photo and follow thusly:
  12. For some context: https://www.youtube.com/watch?v=Qf7nI03wRWc
  13. Before I head to the print shop for my usual method of making a template, does anyone have or know of a line drawing of the Ice-Stroyer as pictured?
  14. Yes, thank you. May your side prevail in State of Origin.
