Ok guys, The first engine is running, the second one is almost done. They're identical. This second will be used to drive a ferris wheel. Key question is : will this work...? This 2 cylinder runs at 1000+ rpm, the ferris wheel will make one revolution every 1 or maybe 2 minutes (maybe even...

Most important while tapping small holes is hand holding the workpiece. I never use T-bars on the tap-holder. I always use cutting fluid. After reading this topic I will try and use WD40. Just maybe it will cut even smoother. Never to old to learn...;)

Indeed, I would change supplier to. If I'd buy say a 9.2 mm drill-bit I'd expect it to measure exactly that...! And if I buy a 6mm brass rod. I expect it to be a h8 tolerance, no more no less. !! Bronze is another story, the production process does not allow close tolerance, so bronze will...

Mine to...! :wall:

Hi, This is how my screen looks like while drawing. The conversiontool works very well and very fast.

Thanks Brian, And indeed we're all proud...! Most people can not even start to imagine, but a few of my boys are even willing to come to school, to speed up things, working on these engines... during this Christmas holiday..! I'm really glad I can motivate these youngsters. (14 to 18 years...

And yet I've seen a movie of such na engine, I'm 100% shure...! There was an ingenious hit and miss system to be seen.

Hi, Somewhere I saw a Stirling or vacuum engine 'hit and miss' movie on the net. I don't find it anymore. Someone seen it also and can give me the url..? Thanks in advance.. Chris

Hi, Did not read all the posts, sorry. But what I would consider is making the cylinder out of cast iron or stainless steel. I would never use aluminium. A vacuum engine is rather 'dirty' engine. To keep it running it need to be cleaned from time to time. In combination with the use of an...

Hi guys, Where do I get small honing tools and is willing to ship to Europe(Belgium). I was thinking of 3/4", and even smaller. I need these to finish stirling engine cilinders. Or maybe there's someone out there using homemade honing tools, and is willing to share his idea..? Thanks in...

Correct...!! Two golden rules 'to stay clean' : 1- Do NOT visit obscure site 2- do NOT open doubtful mails That's all there is to. Chris
