haha yeah an incredible steady hand well i did make the first CNC out of MDF wood everything drilled out of hand, then i replaced components made witht he verry same crappy machine. then after a year i thought it was time to drop some money into alumnium. still as cheap as posssible since i was still a student. i designed my machine with the ballscrews and linear bearings i already had, and only used existing almumnium profieles. since my wooden cnc could not mill out complete parts of 15 mm thick alumnium. i made a pocket into wood where i could drop in the alumnium flat stock or L profiele i ordered online , just to drill the holes and the countersunk stuff. since the cnc was crappy at best, i needed to work around it. still i could drill a pilot hole with far more accuracy as i could do by hand.
so thats how i ended up with this cnc mill. started out with 8 wooden planks , 3 all threaded rods and 3 cheap steppers and a controller board of only 40 euro. used gass hoses as coplings , steel flatstock as linear bearing with skate barings etc its funny if i look back.
