Awesome. So I typed the numbers into a spreadsheet, did a linear regression, and got a pretty graph:  The slope of the lines is the average wattage. If we assume an average on cycle wattage of 165 for each machine (they all were practically identical), then we can conclude the following rough figures:
| Avg. Watts | Heater Watts | Refrigeration Watts | Duty Cycle | Relative Capacity | | Ginny 1 (R124) | 65 | 23 | 43 | 30% | .58 | | Ginny 2 (SO2) | 63 | 15.6 | 47.4 | 32% | .55 | | Ginny 3 (SO2) | 29 | - | 29 | 18% | 1 |
.. so in my own opinion, we probably have enough data to move on to the next phase reset the counters, and convert Ginny #2 or #3 to R124. I've been using the CK as sort of a reference point, so I'd vote for Ginny #2 to be next, personally. |

Wow Ginny 1 & 2 are so close. Love the pretty graph!! Looks like Ginny #2 gets R124 next.

I thought we should have some pics of Ginny #2 frost line with so2 in its veins.  DSC00867 on Flickr  DSC00868 , on Flickr  DSC00869 on Flickr |

Does kinda look that way but the door was almost never opened. That effects the frost patterns also. And the pig evap units were sometimes to low with the factory charge and didn't return oil right. |

It looks like the right side of the pig has a higher line than the left side. At any rate, I've never seen a pig evaporator frost up all the way or even perfectly even for that matter. I'm going to pop some corn on the ol 36 GE stove...this is getting good!

Well now I have done it. I decided to get us a hi pressure reading before I shut it off Ginny #2 and convert it. The screw in the float is stuck up good. I soaked it with Supco88 and mineral oil for about an hour and then I tried to hard to get it out. Stripped the splines out of the screw.   #$&^@% |

I thought I remembered one of us dealing with this before. |

Oh no! The one in my DR3 came that way. The manual on page 62 recommends drilling it out with a 15/64 bit max, and suggests that you might wish to use a gas mask as a precautionary measure...
If all else fails, would it be possible to put one of those self-tapping valves on the line to the float, get the SO2 out, then attack the purging screw with more aggressive means?

If I have to line tap it I will latter cut the line there and add a filter drier as long as that won't mess up the test. |

I can send you another screw.
