Hello Ralph... I have built your original compressor from the photos you provide. I really like its form, rigidity and functionality. A great design. I plan to modify mine tonight into a full stroke design as some have suggested. All you need do is (...) (25 years ago, 29-Sep-99, to lugnet.robotics, lugnet.build)

Why is this two stage? I could not follow this design clearly but are you feeding the output of one stage to the input of the next? Two compressor pistons in parallel is something else (double acting?? I am not sure what)... Cool design no mater (...)

Hopefully there are enough details shown to reconstruct it but if you have any questions let me know. The actual (...) (25 years ago, 29-Sep-99, to lugnet.robotics, lugnet.build, lugnet.robotics.rcx)

The page on compressor comparisons is really informative. I'm honoured that you felt my design was worthy of testing. The reason I made it a two stroker was to "balance" the load on the driving system. Michael Powell's compressor tends to "lump" (...)

(...) 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. (...) (25 years ago, 29-Sep-99, to lugnet.robotics, lugnet.build, lugnet.robotics.rcx)
