Thread: Guitar neck CNC

You can do either, I have done both options, one machine the neck and headstock seperatley and glue them up, and the other way glue a scarf and then machine it as a complete unit

Thanks for the reply Steve.

Could tell me the pros & cons you worked through and is there clearly a preferred method?

It seems doing the headstock by itself would be simpler cutting and the tuner holes could be drilled at that point.

I'm guessing gluing the machined parts would be trickier than gluing a blank.

Thanks,

There are more combinations available when you machine them as two seperate pieces and then join, joining is not an issue, just pop some small location holes in the cnc program, that way you can join them easily.

the good side about scarfing first is that you can run a complete cnc program and carve it all up at once, so very little finish shaping by hand required

Hi.


I have a fretboard modelled, tapered radiused - compound no less - and all the fret positions for a number of scale lengths to hand.


Do I make in modelling terms the fret line the centre of a .023" dado ie slot? Will the model programme go so low? Are there settings to be changed? workarounds?


Thanks,
Rob.

...well...I have a couple of blanks already scarfed ...can you tell me how to set the scarfed blank up in Rhino or the like so that it's not an oblong with most of it air above the neck shaft?

I'v fiddled & fiddled but haven't cracked it yet . There must be a work 'round!

Thanks, Rob

Unfortunatley I dont use rhino, I do all my 3d work in aspire

Right - Aspire not Rhino - but what are the x y z values for a scarfed up blank - or how do you instruct the machine to cut the back from 0.75" not 2.75" (say) the level of the headstock only?
