=== 30 Essential items for building and assembling a guitar body ===
 +
The following list of items is what '''''_I_''''' found to be essential for building a guitar body in a timely fashion. You might be able to do it with a completely different stack or simply less items.
 +
 +
# Wood
 +
# A CNC router

# A long mill bit with 6 or less mm diameter (rounding radius of <= 3) that works all the way through 45 mm thick wood
 +
# A sanding block
 +
# Sanding paper 40-5000 grit
 +
# A router table (can be easily constructed from a template router)
 +
# An orbital sander (well, not strictly necessary but it safes lots and lots of time)
 +
# An oscillating belt and spindle sander. (also a huge time safer)
 +
# A band saw (you can easily find your way around this one, but it's a huge comfort)

WTF

This project page is about building a DIY electric guitar in PacMan style. Pickup-, control- and neck design are copied from a Telecaster guitar. We are going to use the CNC mill to create the body. This page is about the e-guitar i built. :)

30 Essential items for building and assembling a guitar body

The following list of items is what _I_ found to be essential for building a guitar body in a timely fashion. You might be able to do it with a completely different stack or simply less items.

  1. Wood
  2. A CNC router
  3. A long mill bit with 6 or less mm diameter (rounding radius of <= 3) that works all the way through 45 mm thick wood
  4. A sanding block
  5. Sanding paper 40-5000 grit
  6. A router table (can be easily constructed from a template router)
  7. An orbital sander (well, not strictly necessary but it safes lots and lots of time)
  8. An oscillating belt and spindle sander. (also a huge time safer)
  9. A band saw (you can easily find your way around this one, but it's a huge comfort)
  10. Wood drill set
  11. Metal drill set
  12. Screw driver set
  13. A set of hex keys
  14. A wire cutter
  15. A solder iron
  16. Solder tin
  17. Guitar electronics
  18. Gavitt Wire
  19. A multimeter
  20. Shielding tape
  21. An air brush
  22. A wood primer that also acts as a filler
  23. Compatible paint
  24. Compatible lacquer
  25. Car polish
  26. Rubber (nitril) gloves
  27. Masking tape
  28. Forstner bits
  29. Milling bits with a thrust ring for the router table
  30. Respirator mask

That is a video of the pacmancaster before adjusting neck, bridge and pickups. Let's see if i can get it right on my own. Stay tuned.

Lessions learned

The following "lessions learned" reflect my current level of knowledge which might be not very high :)

  • It seems like if the neck is good, the bridge in alignment and the body follows some simple rules - you get a good guitar.
  • the body design has to adhere to following rules for a good sound:
  1. If you do a solid body design avoid large cavities, especially under the pick guard.
  2. Avoid destabilizing the body in the neck axis.
  3. You can tune the guitars resonance frequency by removing material (but how much depends on where you remove material. Removing material inline with the neck has the greatest effect)
  4. The neck pocket needs to be perfectly in alignment and fit. Sound waves need to pass freely between neck and body.
  • Unless you are very skilled you should at least CNC the neck pocket.
  • If you mill a very deep profile you run into risk of getting the milling head stuck. Instead make a circular pocket (following the profile) about 1.5x the mill size (and adjust your step over accordingly). That way you'll create a profile that will be milled by two circular operations (they should partially overlap) per step down. Also vacuum thoroughly all the time and try to find settings that avoid long chips.
  • Certified mahogany is a real nice material for milling but hard to get the paint job right. Pretty homogeneous (nice for milling) on the one hand and on the other with large pores (not nice for the paint job). Ripper told me about a filler material you can use to smooth it out and apparently Gibson does it that way because they mention it in a YouTube video pk sent me.
  • The following videos pk sent me are very interesting, not only because the reveal methodology but also because it pictures the industry.
  1. https://www.youtube.com/watch?v=nu6wCqqPkew
  2. https://www.youtube.com/watch?v=uVU86GGV07A
  3. https://www.youtube.com/watch?v=VbU1R4KDymw
  • The 2 first passes of sanding the wood right before painting are the most important ones. Yeah i know it's pretty common knowledge but I want to remind myself and maybe others to do it properly.
  • Do the first pass in direction of the grain. Do the second pass orthogonal to the grain, and water the wood first.
  • There are dedicated sanding liquids. I want to get some and compare it to using just water.
  • There is a ton of dedicated tools for even the smallest things. Get some.
  • Metalab doesn't have the space and tools for a real high quality finish.
  • Pockets are hard to sand and paint. Rather us engravings for visual effects.
  • Steep concavities on the profile of the body are a real challenge to sand and paint.
  • Building a high quality neck is some next level stuff but building a high quality body is not that hard
  • Banding e-guitars is only done for aesthetic reasons.
  • Use sand paper to "cut" masking tape at edges of the workpiece
  • High-end guitars use shielding tape in all the electronics hodling pockets.

Ideas

  • Build a unibody guitar. neck and body out of one piece
  • Enhance the guitar with electronics. e.g.:
  1. Decorate with addressable LEDs
  2. Add an equalizer and maybe other analog effects. Or maybe build and use external effects processors to tune the guitar to a specific sound and than integrate those effects with fixed settings hidden in the guitar
  3. Use LEDs on the fretboard for learning (see: http://www.fretzealot.com. But do it better
  4. Built-in recording to sdcard?
  • Build an aluminum (or maybe steel?) guitar with a slight spring effect in neck axis. make that "spring" adjustable in hardness as well as resonance frequency.
  • Tune the pickups by attaching an electromagnet to each of the poles and manipulate magnetic strength individually
