By `ek John! That were a mind blast! :clap: Much appreciated, thank you. :thumbup: I always re sleeve pistons to a nice fit in the cylinders, as a matter of course....... I`ve been looking at piston lengths this morning...... Don`t have much leeway...... ::) Guess I could make longer pistons, & chamfer the piston "side" to clear the port area........ PTFE sounds good to me. I never gave plastic a thought! :scratch: Is that what we called Delrin, when I was working?.......... I`ve got a bagfull of it under my bench! :) Thanks Guys for your input. David D. |

Hi David, Delrin is a different material, lower melting point and nowhere as slippy. It also absorbs water and swells, but not much. Mechanically I don't think it would stand up to the abuse, esp at the gudgeon pin area. PTFE is really slippy, I have a 50mm section about half a meter long. You have to hold on to it tightly or it will slide right out you hand :ddb: |

Source for PTFE and other small stuff. they are all much of a muchness on price and postage. This is one fairly local to me. http://www.nogginend.com/index_files/Page2153.htm John Do have a look at the train set at the bottom of the home page. |
