Hi Folks ;
I just discovered some youtube videos for my favourite machine - the Elna "blue top". Including two 28 minute videos for changing the camstack gear. I've got a sweet Air Electronic that needs this repair < always scared me > but I might give it a try now ! :-)
Here's just one link - several more available :

The youtube repair guy mentions the common cause of damaging the camstack gear on these machines - which I learned the hard way - - reversing the direction when using a double-cam - - that's how I wrecked my Air Electronic ...Now I just need to find a source for the gears .. When I last looked - several years ago - the USA - to - Canada shipping made it too expensive to buy from Ray White - but I might have to look him up again - to see if it's still prohibitive.
