Amazing result, congratulations! I had to choose between the last opportunity to fly indoors at Shawbury this season and Old Warden, having had to miss the April indoor session I felt the need to prioritise that. However I’m keeping my fingers crossed for next year, I have a number of small diesels and Cox motors from the 010 upwards that I’m itching to use. I need to knock an Ebenezer together in the meantime and get cracking.

Another to try is "growing " the piston by heating it until a dead match leaves a mark then allow to cool. A variant on this is to heat the piston in the cylinder and cooling in oil while twisting back and to. Not guaranteed result but worth a try. If no good result take out con rod and insert a tapered mandrel made from a bolt or similar.Tap gently trying for fit until happy. All at own risk of course. I think Klippy may correct me on some points..

Great tips on restoring old engines - thanks Danny .

Today was the annual Ebenezer comp at the Mayfly Old Warden and once again we were blessed with good weather B)

There were a good array of models from the original Bert Striegler Ebenezers through to the weird and wonderful world of flying ponies... yes I said flying ponies and it flew very well too thanks to Phil Worth's skill of flying unusual designs. There was great four engined B52? Boeing? which flew well too. My mate Mick's Snoopy piloted Striegler design was going well and Mr 'Wonderfulcat' from youtube delighted us with an off the airfield flight with his Vampire-enezer . Unfortunately I seem to have forgotten to take any pics :(

I did get a shot of Andy's very nicely painted and particularly nicely flying Ebenezer, he's even got a half decent glide out of thing !!! Ebenezer normally guide slightly off the vertical :blink: - top trimming.. only wish I knew how he does it




The 'rules' of the Ebenezer are that from the array of models just 6 are chosen by a team of non aeromodellers to compete in a fly off....

...anyway to cut a long and not very well illustrated story short I made it into the fly off by the use of eye catching cartoon characters, others used pink paint and tassels !! ..Pink seemed very popular with the judges ;)

My flight covered the entire length of Old Warden airfield, landing just short of the river and in the rough nettle patch ...which made recovery interesting in shorts :oops:

Victory is governed by the traditional use of the clap-ometer and I found myself in a tie with a Cox 010 powered low winger which produced a lovely spiral climb to some impressive height ....

...anyway this is a very long winded way of saying I did not expect to posting this

Regarding restoring compression on old engines I've just found loads of methods on You Tube Here is one
Another is electroplating nickel onto the piston and one using a "Magic Fluid" Worth a watch at least The clamp used appears to be a gear/bearing puller.

Congratulations. I hadn't a clue what an ebenezer was before I read this thread! I'm sure you make it look much easier than it is in practice...
'What the hell' is always the right answer...

Here is something that I wrote about ten years ago about Ebenezer's down under, it's still true nowadays wherever you live ;)
