Sliding Valve Air Engine (Remix)

thingiverse

This is my remix of kmccon's sliding valve engine. Please forgive me as I may have several versions of the same upload with different comments as I am unable to confirm which upload went thru successfully. Added the follwoing: 1) New weighted flywheel. Slip in 5 3/8" bolt nuts (14.2X8.4 mm) 2) Tighten tolerance on crankshaft for a better fit on the 608 bearings. You will need a bit of filing/emery work on the eccentric and flywheel for snug fit. 3 Integrated hose barb with the sliding valve cover. 4) New adjustable slider. This allows for more precise adjustment of valve timing. With valve cover off and with eccentric rod fully extended, align the slider valve with port hole. You will hit the "sweet spot". You my wish to just upgrade to the adjustable slider which may improve the performance of your existing build. The print finishing could have been better but I was concentrating more on the running efficiency of the engine. With the help of an adjustable slider for proper timing, even a leaky engine will run quite well. I am able to operate the engine by blowing into it. I operated the engine "dry" as I am not getting improved performance with oil lubrication. I will need to try a silicon lube.
