The Cheddar engines are fine engines, I used to be Chairman of Cheddar steam club some years ago.
First, when running on air there is no lubricant as when running, as they were built for, on steam there is a displacement lubricator which when the steam goes through the lubricator it takes some of the oil with it thus lubricating the cylinders & cylinder pivot. That little engine you have there should run very well for many years!t
he cylinder piston seals should be availible maybe from Stuarts as they bought the rights to Cheddar engines when Cheddar closed down. The end covers ARE pressed in but they should come out with some GENTLE help! You do need to use a ‘Steam oil’ as other oils don’t mix with steam properly.
Bob Abell,
Its an engine you can strip down to the last nut & bolt, It’s not a ‘miserable little steam engine’ by any means, I have an engine using the same components in an ‘inline’ configeration the ‘Cheddar Puffin’ fitted in a TID tug, It had many hours on the engine before I bought the model from Cheddar Models as it was one of their ‘Demo’ fleet. that would be over 10 years ago & it still runs like a swiss watch! over the years I have only had to tighten a couple of nuts, Its covered in oil but that is what steam is all about, If you want a clean running power unit then stick to electric! as for ‘running it for an hour on an electric drill’ best way to ruin a good engine!
Hope this helps
Cheers
