CNC me pt. 3 – creating realities

Having at least a plan for the cross table I started working on the parts. I struggled for a while trying to find a place with the means of doing precise cuts and drills into aluminum. In the end I did the cutting in a former workplace of mine and had to do the drilling at [c-base] of which I am a member for about a year now. There I had to cope with a cheap drilling stand. I built me an improvised guide to at least have some precision in one axis.┬áSome holes I had to turn into long holes to be able to adjust to tolerances. Those don’t look so good but I hope it will do.

I found some basic flaws in my design already. I made the mistake of not taking sideway pressure from the drill itself into account. The telescope slides have a sideway tolerance of about 1mm. I will continue anyway, maybe I find a way to correct this by adding guides or the machine will at least give me the means of drilling exact holes and help me build the next one ;)
