Love the gears  8)

The reason the acrylic I gave you didn't work was because it was polycarbonate - Sorry  :oops:

I'd better get some numbers to you soon as well

Neat gears  8)

Those 80mm masks look ok, were they with the original figures I gave?



Robert, they were with the second set of figures. The original set had the slits so close together that the supporting struts also got burnt away during the cut. You might want to look at the designs for the other two as they may need adjusting too.

Once you are happy with the design I will cut them for real.

Just for a laugh I made some planetary gears (tenuous astronomy link) too.
What sort of diffraction pattern would that create!

Is it an SCT one with the big hole in the middle?
