@kilh, sorry I wasn't much help, sounds like you have already done what you could to make things easier on yourself. One other possible suggestion. On one of my gardening message boards, a lady that was confined to a wheelchair had a lowered area of the counter where she used a portable counter top burner to do her canning on. The good heavy duty ones like the Waring Professional Extra Burner will probably run about $170. Reports are that it works well with the smaller canners, but if you have a larger sized pressure canner it takes too long time to come up to pressure. I really have not looked into them much, maybe there are heavier duty models than that.

At a week out from my TSR, I'm still feeling very little pain, I'm wearing my immobilizer, but leave my wrist unhooked for much of the time. Just keeping the elbow lock on keeps me from flinging my arm around. I chopped onions and peppers for chili last night by keeping my wrist locked and moving my torso back and forth, kind of clumsy and messy but got the job done. And still easier than trying to use my left hand. Next appointment is next week Friday when I get the stitches or staples removed.
