cajon   CAD designs for a DIY box drum

overview

this design is based on a scale drawing by Joe Cruz [PDF 📥], with some modifications made:

  • 🕳️ make an asymmetric, irregular sound hole
  • 🎛️ add a knob for tightening/loosening the snare
  • 🥁 use two 40-strand snare wires, for extra crisp!
  • 🪑 customize the height to fit my personal ergonomics
  • 🪵 adjust dimensions to meet the constraints of my available wood stock

design constraints

  • 🧰 must be buildable without the aid of power tools (a power drill is ok..)
  • 📏 any continuous solids must not exceed the available plywood board dimensions (300 x 600 x 6 mm), the implications:
    • the box top, bottom and sides would have to be laminated from two layers (the upside: no rabate joints to make)
    • as the box width is constrained, its depth will have to be adapted to keep some rectangular proportions (it's tempting to make the front/back and the sides the same maximal width, but perfect squares may be less desireable as they will produce more standing waves)
