Description
Stand it on a mug of hot water and give the flywheel a flick. It keeps turning for as long as the water stays warmer than the air.
No fuel, no batteries, no switch. A Stirling engine runs on a difference in temperature, and this one is built to need very little of it: the big flat chamber takes heat from the mug underneath and loses it through the top plate, and that difference is what drives the piston and the flywheel.
- How to start it: set it on a cup of freshly boiled water, wait a minute for the base to warm, then spin the wheel by hand. If it stops, the water has cooled.
- What it is made of: mirror stainless steel base, glass cylinder, bearing-steel shaft on precision bearings, zinc alloy flywheel, gold finish. Runs dry, no oil.
- In the box: the engine, assembled. Nothing else.
Who it is for
Someone whose desk already has a caliper on it. It is a physics lesson you can leave running during a coffee break, and it is quiet enough to do that in an office.
A model, not a toy for small children: the glass cylinder is thin.

Shipping and returns
Free tracked shipping on every order to the United States, Australia, New Zealand and Canada, with no minimum. A few items ship to a shorter list of countries, and their page says so.
Orders leave within 2 business days. The delivery time for your country is shown under the price of each item. In the United States the Mini Drill Press, the lathes, the XYZ and XYZR micrometer stages and many of the tools ship from US warehouses and arrive in about a week or less. Items shipped from overseas take one to two weeks, a few larger ones two to four. You get a tracking number by email as soon as the parcel is scanned.
30-day returns from the day it arrives, unused and in its packaging. If it arrived damaged or faulty, we pay the return label. If you simply changed your mind, you pay the return postage and get the full price of the item back. Email support@arvonelle.com before sending anything back.
Before you order
Do I pay tax or duty? In the United States, sales tax is added at checkout where your state charges it, and the total you see is what you pay. For Australia and New Zealand nothing is added at checkout. If a carrier ever asks you for a fee on one of our parcels, don't pay it: email us first and we sort it out.
What if a part breaks? For twelve months, tell us which part and we post a new one free. No return needed.
Can I cancel? Yes, within 24 hours of ordering, no questions asked.
