I appreciate the thorough explanation. Your description helps me form a picture in my mind of how this could work in my situation.
My arms and back are not what they used to be, LOL -- I used to do canning for 12 hour shifts on the weekends, trying to put up stocks of fruits, preserves, veggies and meats of all kinds. I could not afford an extra freezer, so when I got a good buy on something -- it all had to be processed right away.
I'd do the fruits first, because those took the shortest times, especially in a pressure canner. Then, I would roast the chickens or beef roasts while the fruits were processing. Later, I would do the vegetables and then the meats.
I was able to rescue my canner, although it would surely need its gauge calibrated and a new gasket. Otherwise, it is all intact -- I even have the bottom rack that came with it.
Thanks again for inspiring me to try to get back to this again.
I do not load it inside, I put the canner with about 3" of water and the rack on the burner outside and start the burner without the lid. I usualy hot pack my foods and I have a medium size pan of water boiling in the house. I carry the jars outside in a backing pan and I sit them in the canner then I add enough boiling water to fill to the rim. Then I put the lid on the canner it usualy does take some time to get it up to pressure but I have a 23 qrt canner so it proly takes me longer than it will you. Once it gets up to pressure I have never had it slack off it stays up there. I always start my time when it reaches its pressure that is why I try to start out with boiling water so I am not over processing / cooking the product. Once my time is reached I turn off the burner and I let it sit in the canner for around the same time as the processing time. This is usualy enough for the pressure to relieve. Then I check the pressure by lifting the weight and if its all good I take off the lid and remove the product. I put a big towel down on my picknic table and afte I tighten the lid I turn the jars over on the towel and leave them upside down for about 30 -40 minutes then I turn them right side up and let them cool completely before I move them indoors. I have only every had one jar not seal by using this method and afterward I found a small nick on the top of that jar so it was not the method it was the equipment. I don't know if I am doing everything right, I just know it works for me.
