To: Genghis,
To my knowledge, on small engines used on general aviation aircraft, they do not reline the cylinder. They bore it out to remove the damaged surface and then replate with a propriatary metalic coating system and then hone it out to the original bore size. That way, they can utilize the original pistons or, new pistons of original size. The ammount of times this can be done is limited by the manufacturer.
By the way, Being from the colonies, I don't understand your comment about the hundred year old broom. If you you were alluding to the fact that I date back to ancient aviation history you should have correctly said 70 year old broom (in December). But as the commercial on the telly says I keep on ticking. The last two aircraft I worked on in a consulting capacity were the A340 and the A3XX. In two weeks I will most likely be working on constant speed drives used to supply electrical power to jets just like the ones' you fly.
Cheers.
