Hi

Took the piston out of a TE that had clocked up about 12 hors running yesterday to find the string piston ring all but gone, turned to muck each end of the cylider.
Not wanting to repeat this I machined a piston ring 11thou over bore from Delrin angle split the ring and put it in the packing groove. Put the lot back together and steamed the engine. After 20 mins running the piston runs in the bore better than any ring set up iv ever used! smooth and seals very well.
Dont think it would work for super heated steam but on saturated it seems just fine. Il post an update after 15-20 hours.
