Desktop CNC

Design parts in CAD and machine them for real on a desktop CNC router.

Design parts in CAD and watch a desktop machine carve them from wood, plastic, or metal.

Telescope Making

Make a reflecting telescope from scratch — grinding, polishing, and figuring the mirror yourself.

Grind and polish your own telescope mirror by hand, then see the sky through glass you figured.

Which is right for you?

Choose Desktop CNC if…

  • Make precise, repeatable parts a hand tool simply can't achieve.
  • Bridges design and the physical world, so you draw it, then hold it.
  • Endlessly useful: signs, parts, inlays, prototypes, and more.

Choose Telescope Making if…

  • A genuinely profound payoff: see the sky through optics you made by hand.
  • Meditative, low-cost craft with centuries of tradition and community behind it.
  • Teaches optics and precision you can't get from buying a scope.

Before you commit

Desktop CNC

  • A real learning curve across CAD, CAM, and machine setup.
  • The machine and tooling are a meaningful upfront cost.
  • Dust, noise, and chips need a dedicated, managed space.

Telescope Making

  • Figuring and testing a mirror is hard, slow, and unforgiving of impatience.
  • You need a dedicated grinding space and a way to test the surface.
  • It's a long arc — first light can be months of work away.
