Find contentI think that could be the problem, but am not sure of a solution for it. I have tried using a 1.5 inch fender washer with a 3/8 ID for my seal,which fixes my problem of the slow plunger rod; but it only gets a 40% seal and does not fire a dart. I have no access to large hardware store here in Hong Kong and my hardware stores do not carry fender washers, is there any other way of centring the plunger rod?
Hey F man 47, glad you liked the design! Sorry about the late reply, I have slowed down with nerfing and only occasionally check the forums. As said before, I am almost sure a centered plunger rod is your problem. The best way I was able to center mine was by re-drilling the hole in the 3/4" end cap so that it is perfectly centered. I also made sure the CPVC "U" shape was perfectly level. If the centered plunger is your problem, that explains why the seal isn't 100% too. Hope that helped!
