Thread: Jan Ridders Pressure Controlled 2 stroke Engine
03/01/2019 23:13:09

I finished this engine in June 2009 and I can now report that with a great deal of help from other engineering friends, in January of 2019, I now have a working engine!! After displaying it at various model engineering exhibitions where it looked quite pretty but didn't actually work, two of my friends and I spent a total of 20 man/days before achieving what almost appeared to be the impossible!

Happy New year

David

Thread: Stirling Engines
12/08/2012 19:16:39

Over the past several years I have built and exhibited many Stirling engines, some of which use a diaphragm instead of a power piston. I usually use a latex glove to make the diaphragm but I find that they tend to biodegrade in a very short period, very often as quickly as 5 months. Can anyone suggest a more likely source of less biodegradable material that I might try. Condoms and ballons have been suggested but not yet tried.

Thread: Jan Ridders Pressure Controlled 2 stroke Engine

Hi John, All was going well until a friend tried to adjust the gib strips on my Warco lathe - and bust one! The replacement from Warco was greatly oversize and their suggestion to scrape it down to size was a bit fatuous as it was about 0.125" too thick. Anyway, with a little help from my friends, I have reduced it to size and now have a working lathe. I shall be away all of next week, but on my return I will make a concerted effort. How is your's doing?
 
Kind regards, David

I have just completed Jan Ridders Pressure controlled 2 stroke engine from the plans supplied in ME. I noted that in the updated You Tube file that Jan had replaced the piezo ignition and I am going to use a Tim6. It should be ready to run in the next week or two. But will it???????????????
