Re: New to the group, new owner of a 1200 Mill

[Chainlink]

I've never made a guitar neck with my cnc'd 1200. If I were going to do 
something like that,I would not depend on moving back and forth on the x 
axis; there's just too much backlash. I'd have to go back to x0 and run in 
one direction to get the best result possible.

So, I would trust repeatability if I adjusted my gcode to account for the 
backlash (by avoiding cutting in the x-, and if the work piece was either 
not too long to have whip or deflection from the router bit, or was 
supported from underneath by a roller, or was run slowly enough to not be a 
problem.

My experience is in making long 1.5 inch -5 threaded dowels no longer than 
about 4 feet in length and making small lidded jars with contoured lids.

Re: New to the group, new owner of a 1200 Mill

Hi Joe,

I fear you may be right about the tolerances of the ornamental mill.  Just 
incase though I will, at some point, upload a few pdf files of guitar necks.
I have attached an image of my first attempt at a lap bass guitar, 8 
strings.  This was made on the Larken Router and is a piece longer then the 
milling bed, so it was fed through and back many times carving both top and 
bottom.  Came out less then an 8th of an inch longer then designed.  You 
will notice the body is pretty much a mirror or symmetrical left to right. 
 It would be possible to build guitar bodies if you wanted to take the time 
to create the various templates/guides.  Once that was done the Legacy 1200 
would bang them out much quicker then the Larken. 

If I can get the Legacy 1200 mill to plane down material I will be happy. 
 34" custom guitar necks can wait.  Though with what little I've used it 
thus far I believe if an affordable and accurate DRO system was added it 
could make guitar necks and really help me out with layout of long piece to 
improve my accuracy when feeding them through the CNC router.

PS the Lap Bass was carved from a solid block of fir because that is what I 
had laying around.  A semi hollow body, more boxy version is in the design 
phase.

hi tim!...my first thought after reading your post is to say that you might 
not be happy with the tolerance level a legacy, converted to CNC, could 
provide you, especially since you are accustomed to working with some very 
nice, precision equipment... you could add linear bearings to the three 
axis', and stepper motors, and all the other bells and whistles needed to 
do the work you want, but in the end you wind up with a machine that might 
not live up to it's billing and your standards... plus the legacy's 
capacity is a bit small for a guitar body, I would think...a guitar neck 
would fit though...the idea of carving/milling details into the body and/or 
neck of a guitar is excellent, and could have great potential for some 
sales...all good and interesting stuff...joe biunno

Hello TimWelcome to the group.I am sure that your gamble (as you said) on your 
Legacy, will become a wise investment for you in your future.
Please feel free to check out our archives, I know that you will find them very 
helpful for a very large over view of what has happened in this group over the 
last couple of years.
I can not remember anyone making a Guitar on the Legacy, but I know that it 
should be possible to do.  This might be a good topic for not only you to do, 
but for the Group to learn howit can be done, for others with-in the group to 
learn.  
As far as Legacy the company. IF you ever need parts, Cindy is the Lady to talk 
to for the LOM parts, Legacy as a company has moved on to the CNC world and 
will/can-not help us for general info.  (but I was assured that all wearable 
parts on the LOM can still be bought from Cindy at Legacy.)  We also have a few 
people in our group, who can make parts and other idoms that you might want for 
your machine in the future.( But we will cross that bridge in the future.) 
Again ... Welcome aboard.  I personally, am looking forward to learn how to 
make a guitar.
Have a good day.C.A.G.

Just a quick hello to introduce my self.

I live in western Washington here is the U.S. of A. and I design and build 
stuff.
I have owned a Larken CNC Router or Camtool 24R as they are known for about 
five years.  I've added an alcohol misting system so I can fairly reliably 
cut aluminum parts.  I also own a little Sherline CNC lathe/mill for 
fabricating small parts.  Although I mainly build or modify tools and carve 
things out of wood.

I was actual looking for a second hand planer when I ran across an 
Ornamental Mill for sale on the mighty Craig's List.  Thinking I might be 
able to semi-convert it to CNC and use it in production work I gambled on 
the purchase.  Hopeful I was not to foolish?

Anybody ever make a guitar neck on one of these babies?
