I am showing the ease of setting up john walsh's cnc trace software and rollup II ,to
trace out a violin back using any computer
In the end i will have a *.dxf file ready for software to create a toolpath to cut the
violin back out of maple
If you have questions conact me or john.walsh@logicgroup.com logic group
His software is easy to install ,in minutes you're up and tracing

using the cnc trace software and a portable drawing table (rollup II) we will copy a guitar
pic guard ,creating a dxf file and eventually creating a tool path and putting it on the cnc
machine and cutting it out
Any questions conatct me or john.walsh@logicgroup.com at the logic group in Texsas

Stan,

I'm sorry but I don't see how this is any faster than using a photograph or other graphic. It's now possible with most cad software, to photograph an item or drawing bring it into the cad file place in the background and trace in cad the photo or graphic given you know some kind of reference scale. ( this can be done automatically by some cad software others need to manually be done )

From an instrument building standpoint the 2d outline is only the beginning and doesn't give enough data to create a 3D object in and of itself.

Such as these.

Sorry, not trying to rain on your parade but what your showing, for me as an instrument maker is something we were doing in the late 80's early 90's ( when I was drawing architectural plans ). The middle jpg is a 3D laser scan of a neck. The other instruments where all drawn using 2d dxf files as foundations..... probably drawn using a photograph brought into the cad drawing. ( don't remember )

Blessings,

Kevin

I agree with you ,maybe the musical inst was not the best thing to copy as its 3D not 2D.I am not a person who could use a cad prg but i always drew up furniture plans and now i can digitize them and not scan and then do 1 hour of editting.(nodes drive me )
I sure could use the experience you have for a violing top as i am not into cloud points. Last week i re-designed my dust collector on the cnc ,drew it and digitized it and cut it on the cnc .
I am retired and this is a hobby for me, and i could be doing anything so i'm never an expert but I am not good with a cad prg.
I have a calcom drawing board III (old) and now it has an excellent use again,in fact this 2d digitizing is great on the laser, i take old magazines and draw what i want off the diagams and run it through the laser
