Model Engineering

Machine working scale models — live steam engines and locomotives — on a lathe and mill.

Machine miniature working engines and live steam locomotives on a lathe, part by part.

Synth Building

Build synthesizers and Eurorack modules from kits — soldering electronics into playable instruments.

Solder your own synthesizers and modules, then patch them into sounds nobody else has.

Which is right for you?

Choose Model Engineering if…

You make working machines — there's little more impressive on a workbench.

Before you commit

Model Engineering

A lathe is a real upfront cost and needs dedicated workshop space.
Projects are long — months to years — and demand patience and precision.
A genuinely steep start; machining technique takes time to build.

Synth Building

Soldering has a learning curve, and a dead build means patient debugging.
Eurorack especially is a deep, expensive rabbit hole — costs creep up fast.
A fixed bench with an iron and ventilation is part of the deal.
