hot air fan

[shaun greenParticipant @shaungreen40014]

I was given some drawing that i was told are from an edition of Model Engineer magazine.

 

The drawings were photocopied and the fold in the page has decided to cut some of the measurements off! not particularly helpful

 

I was hoping to make one next week in college and was wondering if anyone could help me out with this either by providing me with the drawing or the measuremtns i need!

 

Would be extremely helpful!

 

Many thanks

Hi There

I can probably supply.

I think I know the article you mean.

It was back in the late 60s I think.

If you have the author name, let me know.

I have built two hot air engines, one from old tin cans from the internet, and one from a machined kit.   Neither worked.

 

I know that friction has to be kept to an absolute minimum, and that good balance is important.   I will keep trying.

 

I have seen a Ky-Ko fan operating at the Clumber Park steam fair.   I KNOW it can be done!   Blame my ham-fistedness.

 

Regards

Geoff

I have built several hot air engines before I got one to work, Since then I have successfully made one for my grandson, which he won’t appreciate for a few years yet. It was made mosly of junk parts like hard drive discs, bearings, and magnets to hold the meths burner; an old electrical switch box as a base and a piston machined from an old cast iron sash weight. The trick is the three no no’s, no friction, no leaks and no loss of patience.
