Thanks, It could possibly be done but I've not tried it. It would have made the air compressor tester more complicated than necessary. As you can see I'm really a minimalist. One of the design goals was to keep it simple yet fully functional. There's elegance in simplicity. -- C S Soh cssoh@singnet.com.sg http://web.singnet.com.sg/~cssoh ...where air is power

The reason I made it a two stroker was to "balance" the load on the driving system. Michael Powell's compressor tends to "lump" (...)
