The length of a slide valve can be determined by the port openings. For no lead the outside of the slide should just cover both ports at TDC. If there is lead allowed the slide is a bit longer than the port edges and is set so the port just "cracks" open at TDC. On my larger models (3-1/2 inch gauge) with cylinder drain cocks I set the valves and check for correct length by connecting a tube to the drain cock on the end of interest and put the end of the tube in a jar of water. Bubbles then tell me just where the valve effectively opens. If you can't get both ends of the cylinder working the same then it is time to start looking at the total length of the valve slide or the valve gear for something wrong. _______________________________________________ SSLiveSteam mailing list Send messages: [email protected] Cancel subscription: http://postfix.45mm.com/mailman/listinfo/sslivesteam Rules: http://www.45mm.com/sslivesteam_guide.html
