Comments sought on new build: A CNC Router for RC Gliders and Planes

Hi njhussey,

Sorry to jump in with a sales pitch (!), but as an upgrade could I interest you in some bits to replace your pipe and skate bearings:

I noticed that the sizes were close, so may be an option. Still open to offers . . .

As for the design, reasonably traditional layout so good start. But the gantry sides look too thin. Consider welding angle iron onto the 5mm plate, or some other upgrade. Same goes for the flat plates holding part of the Z axis rails on (if I understand the dwg).

Otherwise, for balsa and liteply it should get you going . . .

Hi Barry

I think I'll stick to my pipe and bearings as I've already got the bearings thanks. Also I'm doing this on the tightest budget ever...well trying to anyway! For my next machine (oh noooo I sound like everyone else on here now, not even built my first and already planning the second!!) I'll use fully supported precision ground rails or linear rails as I'll probably want to cut ally. I'm going to stiffen up the gantry, just not figured out quite yet how. Was thinking of a back, top and bottom welded to the sides from 6mm steel. Guess with all the weightI'll need to support the rails!
