Thank you Everyone.
All great ideas. and I am going to check on line.I have see some (just guts) of the spring load kind Rodney is talking about. But Patrick has a good question ..how do adjust it?, And how many position will they stop in. I know you push on machine for it to come up and down (right)?
Thank you every on for your help. If these spring load had more than one position they stop in (like so she can use her free arm. That is what I will try to find. Anyone got extra one let me know.
