Absolutely. Not a person on this forum would mind being proven wrong here. I'm sure lots of people would see ~$700 as a small investment for a 3D medium-duty CNC capable of doing guitar bodies and necks. I wouldn't mind being proven wrong at all.

Unfortunatley I dont have the investment $$ at the moment, Because I bought a Roland stika vinyl decal cutter, Maybe come the first of the year........... I am a member of several jobshop type forums, My first projects of that type are converting my mini mill and lathe to cnc (about 450.00 for both)... one thing I didnt consider is most people here dont have acess to a mill , lathe, and welders, where I would be making parts they would have to buy them, I would be able to buy a 96" ball screw and cut my peices out of it instead of buying 3 seperate smaller ones with milled ends, make my own motor mounts, connectors, blocks, etc.... Mine also would not be 4 ft. like his duplicarver, maybe 40X18X5 inchs of travel. I have found 276 oz stepper motors for 35 bucks each,3 axis controllers for 149, Maybe find it on ebay a little cheaper. The rail system dosent have to be as nice as his, the ball screws will prevent play in the system if done correctly.
Just need it sturdy and free moving. I Will draw up the plans, get parts prices Send them to whoever wants them...... Most people want to sell there plans, I'm NOT like that. It will take a little while (a couple of weeks) but hey were here to help each other out!
