Thanks Arbo for the idea, I will have to research this setup. It would simplify the build not having to custom fab extensions off the bearings for the Y pinion motor mount. I'll muck around in Sketchup and see what I can find out about top mounting.
As far as "spindely" looking I see what you mean. I will have a bottom shelf underneath the bed to increase rigidity. Also building with extruded aluminum you can always easily add more support later if there is any flex. I understand the MDF machines and the need for stiffness there, but
extruded aluminum is quite stiff and strong material, I think people see it and think it looks too weak because of the size. I'm always amazed how heavy and stiff it is, but cuts like butter with a carbide saw blade...
I've seen so many monster machines on this site that are "over-built", ugly,huge and bulky. I'm personally trying to find the balance between strength and style, as I am a minimalist by heart. Why sacrific extra materials, time, and space when it you can find a better way?
Thanks again guys for the comments!  |
