Description
Light the little burner, wait about a minute, flick the flywheel. It runs, and the belt turns a small generator on the base.
This is a hot-air engine: heat at one end of the cylinder, cool air at the other, and the pressure swing between them drives the piston. It is the same idea as the low-temperature model on a mug, with a flame instead of hot water, and it keeps going as long as there is fuel in the burner.
- About 160 x 85 x 75 mm. Metal, gold finish, on a flat base plate.
- In the box: the engine and an empty alcohol burner. Fuel is not included and cannot be posted: use denatured alcohol or a similar burner fuel from a hardware store.
- Starting it: turn the flywheel by hand to check it moves freely, fill the burner to under two thirds, light it under the end of the cylinder, wait about a minute, then spin the wheel. With the generator connected it takes a little longer to warm up.
Be careful with it
The hot end of the cylinder and the metal next to it get hot enough to burn. Run it on a surface that does not mind heat and do not leave a lit burner unattended. It is a model for adults, not a toy.

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.
