Post subject:  Making a CNC neck on my shopbot
Here is my second attempt at making a neck on the bot.
The first worked out fine, i just forgot to take pictures.
I do need to clean up my referencing as I flip the neck to do each side. I do it this way because I don't have enough Z travel to just clamp the thing face down.
My goal is to make a slightly oversized blank that I can custom shape quickly with the pneumatic drum sander. I think I am just about there as this cleans up real fast and has just enough meat for me to make adjustments as the customer wants.
Here is a quick video and a couple pics.

Nice work! That did come out great...

Why did you choose to mount it on "it's edge" for machining the neck, versus mounting it flat (fretboard side down)?

I think mounting it the other way, would be easier to machine, and also, cut down on a lot of the "air cutting"....

Regardless, GREAT WORK!

Good Job John.

What is your Z travel?
Nice to see an acoustic neck CNC video. I have seen dozens of video's on electric necks but very few acoustics.

I did it this way as I don't have a lot of Z motion and I don't have a long bit either. The air cutting is due to the software I use (the stuff that came with the machine), it doesn't allow anything but a block shape to start with or at least I haven't figured out how to tell it what the starting shape is other than that. It is a fairly simple tool pathing program and I don't care to take the learning curve on for something more complicated right now.
