CNC to M&M

Well, I have access to a CNC and I have been learning/playing. Saw this from Dan and just had to try ..

Cut the pieces:

Found that the gear, same thickness as spacer behind it, did not spin when clamped. A couple of paper shims above/below the spacer did the trick.


As for the hole/groove in the pocket in the piece on the bottom of second pic above .. the CNC did some wacko things that I cannot yet explain. I filled them and all is good.

Sealed the MDF with shellac but it still did not take the paint evenly. You all know how MDF edges such up the finish. Should have primed the edges. Oh well, not too bad for just goofing around and learning.

you missed one key thing robert, i didn't use any shims, i sanded the thickness of the gear down a bit to get it to spin freely.

I like that - Great IDEA.

I am going to add that to my IDEAS folder to be made some day.

Dan, I suspected there were not shims and thought about doing the sanding. Wanted to keep the sealed surfaces on the gear faces to prevent the 'soak up' of the finish. Paper shims worked just fine and really not noticeable at all. When I make another out of real wood, I'll sand the gear for sure. Thanks.

Looks good Robert!

i was thinking shims at first, then thought that reducing the thickness of the gear a touch (not much mind you) was better. i sanded from the bottom, so not to lose the gear detail on the top.

I like the idea of painting it. Cool.
