Poor baby was constipated! 250 psi worth, that's what was on it when it let go. |

Poor baby was constipated! If SO2 machines get constipated it sounds like CA machines get the runs. |

Well, sounds like you got it unblocked. Sounds like an ingenious way to do it too. The 80 year tune up usually makes the S02 machines run like new again. This is usually all they need. Needle and seats don't wear like the CA machines, they just get clogged.

Now go to the store and get some SO2 and put it back in there.

Now go to the store and get some SO2 and put it back in there. I think i am going to come down there and recover some from something you or your friend owns. Smallest size I can buy around here so far is 120 lbs |

I have a stalled DR2 that you can rob. It ran before it stalled, so it's not a burn out.

Sure am kicking myself for not saving some from your DR3. Would just do a 134a conversion like I was planning but want to play with so2 and filter driers instead. |

Well this is were I should be trying to put a filter drier. And it could be done with some rerouting of the tubing if the flammable insulation wasn't there. If the tube under the float is cut like mine is I was able to lift the evap. mounting plate a fair amount. If the by pass tube was cut it would have been able to go a lot higher. The suction line is long enough to flex pretty good.   Instead I just have to see what happens if put it after the float were I can change it easy if it plugs up.  My sophisticated way of locating the valve during brazing.  While I was going to use a solid core drier I decided to use this 3 cubic inch bead type I had on hand. After checking the specs I see it is made for great filtration and to hold the beads so they don't move and dust off. And yes it has activated alumina in it also. www.emersonclimate.com/Documents/FlowControls/pdf/systemprotectors/brochures/EK_Filter-Drier_White_Paper.pdf  Here it is installed and the vacuum pump is running.

This may be a dumb question and I'm sorry if it is. But with flare fittings is it still considered a hermetically sealed system?

Since I am experimenting I wasn't worried about anything but changing it easy if it plugs. Latter on I may be removing the evap. mounting plate, re insulating and moving the filter were it can't be seen. |

Opps, After pulling a vacuum all night the unit was ready for a recharge. When I recovered the so2 I retired a recovery tank that had been used for R-12 in the past. Well this morning I didn't pay attention and hooked up the thank that had the R-12 still in it, Before I realized I had all ready started to put some in. So I guess we get some CG running on R-12 info from my mistake.
Frost line is a little low yet. After running all day in my 60F garage it runs for about 2 mins 15 seconds and is then off for about 30-31 min. Watts are high at 210 when it starts dropping to 200 when it shuts off. But what surprises me is it is no were near as loud as my DR2 was with R-12 in it. So far it is working great with R-12 in it. May need a suction line restrictor to work in hot weather though otherwise I think the watts would be near full load.+

And this is what annoys me about CK type units.
You even put the wrong refrigerant in it and ended up with amazing run times.
It sometimes feels like trying to compete in a race when you're the only one without a supercharger.

Looks perfect!
There must be some difference on R12 between the older DR compressor and the later Scotch Yoke - high side dome vs. low side dome maybe?
Compressor current is high; that's what my CA-2 draws including 19W of transformer losses and the 12W heater.
A pair of vise grips to squash the low side line a little perhaps?

At this point I think I will leave the low side line alone. Wondering what 134A will do in this with out a suction line restrictor. I think the low side dome is the main difference myself. As quite as it is now R-12 with a restrictor should work good it looks like. |

The real question is whether your wife likes it. If she doesn't like a ball top, she's a fridge hater.
