Re: Household aid for the needy
Joe, if you're serious about building one of these in near future. It took 2 lengths of pipe & had about half a length left over. The width is 6" between fittings which provide enough space for a hand to grip without having the fittings interfere. As can be seen I twisted one of the feet so as to min possibility of having it interfere with a foot or wheel on a chair.
Good luck and bless you for caring for someone that isn't able to do so by themselves.
If this helps you and others, this post has served my intent.
