I am a member of this forum for a long time already. I mostly read forum and never make any post. But now, I have something to share with this comunity!

I finally start to build a CNC router/mill for making RC model parts out from a balsa wood and soft birch plywood. Maybe, if a machine will show better precision as expected, some molds from a dense molding foam can allso be carved, for fast prototyping of composite fuselages.

I dont expect much, as I opted for the cheap build using standard aluminum profiles. They will be mostly bolted and riveted together.

Some technical data:

Power supply and Controller: purchased from hobbycnc.
Net working area: 600 x 400 x 100mm.
Outer dimensions: ~ 860 x 710 x 530 mm
X axis guide (lenghtvise): ball bearings over an aluminum profiles
Y axis guide (crosswise): ball bearings over a steel rods
Z axis guide (vertical): brass sliding bushes over a steel rods
Stepper motors: Minbea 17 size, from a head drive of Epson Stylus 1500 (if they prove to be too weak, I will purchase stonger)

Up to this moment, I cut all necessarry profiles to proper length.

Now it is time to start bolting them together.

And a couple of photos:

Some of the profiles. Cross section 30 x 30 x 2mm.


Some of the gantry parts.


You can visit my Blog, to see more photos of this "project".

So much for now. I intend to start bolting stuff together shortly. I will report here about the progress.

If encounter some problems, I hope to find support here from you guys!

Regards!
