.Notes: You only need to fill the glass by about half. If there s a bit of mechanical noise, just lubricate it with a little graphite to quiet it down. You can scrape the graphite off a pencil with a knife. Do not lubricate it with oil for the oil will mix with dust in the air to form greasy dirt, which will give the Stirling engine too greater friction to run freely.
