  1. Subbed!
  2. Decided what to ditch.
    Next step, connect the holes.

    The build is looking great, but can you explain to me what "de afwerking" is? The thread title is confusing me :D
  4. "de afwerking" sort of means "the finishing touch" in Dutch, almost everything I make is done under that name.

    Connected the holes, or in other words sawed out the inside of the body, also defined the back cover and sawed this as well.
    Sanded smooth the sides that will be visible trough the sound holes.

    Top roughly sawed into shape.

    The knobs are finished.

    Zebra wood, 3 ply birch and a walnut top.

    I always hate making these things at the end of the build, that's why I try do them as soon as possible.

  9. (This small build diary was done before in Dutch as part of the diary about my previous build)

    The rough work
    A piece of wood
    (A leftover piece from the body in this case)

    A set of hole saws
    (| needed two sizes)

    I clamp this piece of wood on top of the table of my milling machine (at work) and saw out the holes (not all the way through).

    Sawing of the knobs of the bottom with a bandsaw gives this
    and this

    Now I can saw of the knobs to the proper and identical length.
    And we've got some rough cut knobs.

    Finishing the knobs on the lathe
    Drilling a hole with a diameter of 4.2 millimeters and a depth of 15 millimeters:

    Tapping a M5 thread and just flattening the bottom end:

    Clamping up my special tool:

    Screwing the knob on my special tool and after that machining the outside:

    Putting on a radius at the edge and after that sanding the knob up to a grain of 600:

    The side of the knobs that's in sight is done:

    Drilling a hole with the proper diameter for the pot shaft:

    Machining out a chamber for the nut of the pot:

    Drilling a hole with a diameter of 2.4 millimeters in the side:

    Tapping a M3 tread in this hole:

    Put some M3 screws in these holes and were done:

    What still needs to be done is putting on six layers of Danish oil.

    And a last minute correction that needed to be done when I was assembling the bass
    It was a nice idea to make a M3 thread in these knobs, but alder is not strong enough for this thread and it came out when tightening the screws.

    The solution:
    Drilling out a bigger hole and gluing in a brass insert with the correct inner diameter, drilling trough the M3 hole and tapping the tread in the brass insert.
    And were done!!

    Goed bezig!
  13. Sanded flat the top.

    And how the grain will pop when it gets oiled later on.

  14. Glued the back to the side on the first body half.

  15. Good job!
    Very interesting project!
    What is the thickness of the back, and of the top?
    Will you put some fan bracing or not?
  16. The back and front are approximately 6 millimeters thick.

    No fancy bracing is planned, I'm going to glue a block of wood between the front and back where the bridge will come, some small blocks to the back to mount the pickups on and a bracing bar along the length of the body where the two halves meet.
  17. Potverdimme, hoeveel kosten die instrumenten van jou gemiddeld? Ziet er goed uit!
  18. They are not meant to be sold, I only build for my personal fun and use.
  19. Glued the back halves together.
