    Didn't think you did Nick! Just wanted to make sure it was clear to anyone reading this. A well constructed CNC using aluminum extrusion is more than up to the task for most of our needs in the guitar building world.

    I want to say again that I am not a cnc expert, I am more rookie than the rookies!
    What info you see here is gathered from forums and discussions from people thru pm or face to face.
    Please for your own good-money and time saving double check everything you read or wait till my machine start to cut before you do anything like that!!!:D

    A T-body won't reveal the time savings but a Les Paul or PRS type carve-top will. The CNC will accurately repeat your shape part after part.

    You can listen to the machine and know it's cutting right or if there is a problem, so while you 'walk away' you are right near by. No different than if you hired the kid down the street to template router bodies out so you can carve some necks. You're listening to that cutter run.

    Your CNC job setup is crucial to get good output quality and that is where the craftsman skill remains.

    I use the end mill chamfering with sunk to prepare the holes,then screw the aluminium angle in place, the axis weight now 8.7 kilos.

    We expect some visitors in about one hour but I manage to paint the CNC bench today black and the sides where the Y axis extrusions are going to rest yellow.:)

    Yes, it's a $300 kit from China. The bed is 91/2 x 7 inches (24x18cm), it can route and laser etch. I´m planing on doing PCBs and maybe invent some contraption to cut frets. Or I could do model 1:4 scale guitars heheh. Maybe I'll open another thread so I don't highjack this one

    Since is is an open bed cnc you can try radius, make drills for the dots and cut slots at fretboards, usind slow feed and speed.
    You are not hijacking but it will be interesting to see the the full building of this cnc at a thread.
    Welcome to the cnc fever!

    Dangerous and infectious fever indeed.
    This was my first foray into CNC, at work.

    I start assembling the X axis ball screw.
    First problem, all the allen head screws I have bought is about 3mm (1/8 of an inch) longer, because when I measure the depth of the holes with my depth meter I forgot to subtract some of the length since the tapping tool cannot tap the whole length of a blind hole.
    The fix was easy!

    I start the leveling.
    Weld one bolt under each bench leg so I can level the machine, I have to grind the sharp edges.

    This thing is very old, although very accurate because I trade it with care , it wasn't possible to get a better photo that is why I have mark where the babble is , I am going to continue and get a better result.

    VFD ,Variable Frequency Controller and 2.2kw water cooled spindle arrived!
    I was between the air cooled and water cooled spindle but I finally pull the trigger on the water cooled because it has a lower noise factor.
    The level of noise when you cut with such a motor is the same as an air cool spindle but at no load condition they say that water cooled motors has a much lower db factor.
    If you have such a motor and you want to protect the water paths from rust, inside the spindle you have to add anti-freezing liquid, like that you use at your car in the water you are going to use for cooling the motor, as a dilution.
