My aluminum custom machined marble game is about half done! I handed off most of the parts machining to an older machinist at work, annoyed at how long it takes me and the large number of cosmetic- and worse- mistakes I made. Countersinking this too far, breaking off that tap, mixing up near-symmetric parts, stuff like that.
Here is a picture of the SolidWorks, and I’ll take one if I remember tomorrow of the real-life. But it is missing too make pieces to really know if and how well it will work. Sigh.
Basically it is $250 of commercial parts plus $2000 of machine shop work (he is doing it for me at about half price) plus $150 of raw materials, and a little extra to anodize and finish nicely. The cranks tilt the top platform, where a marble rolls along traps in a maze (not shown). After the picture below, I lasered out the marble catch tray, that sits in the top section. The actual maze is above the catch tray.
Hopefully another couple weeks and I’ll have the parts together. Then, take everything apart, sand (DA) it all, and off to the platers. The next choice is color- clear or black anodize?
