Nice! --- End quote --- Thanks! Considering the amount of time before you get your current project completed, you probably need another project. A little instant gratification never hurt anyone.

It's looking really well Chuck, and as usual, well planned and thought out first. This is making me look at rebooting my Halo project very seriously. John |

Nice work, especially on the gears and the slave valve system, Chuck :wave:. I have tried that slave valve system with piece of brass tube, suitable size bearing ball, and spring. My humble compressor gives only max 3.2 bar(~46 psi), and can't even move the valve/ball. Reason being mostly too stiff spring. I made a new spring, using 0.010" guitar string, but still too stiff. I'm still looking a way to make a lighter spring. Copper or brass maybe? But (finally) to the point. What is the air pressure, that you use to run your engines? Also, what size are the spring(s)(to be more precise, thickness of the spring wire) on your engines? Just a wild guess, that there is some relation between air pressure and spring tension? And of course size of tubes(volumes), that the compressed air goes through :scratch:. |

not to try and tell you how to suck eggs , but have you tried the springs found in the cheap retractable ball point pens they are a nice size for our use Stuart |

Stuart, I took apart one(all) of my pens, and found out, that they all have ~0.015" springs. Bit thicker than the 0.010" guitar string, that I've already tested. But thanks for suggestion anyway :thumbup:. |
