I see you did not use a rounded cheek spacers on the cores,  perhaps that is the reason your fingers are sore   . I did not use any gloves nor masking tape on the fingers . Re doing it standing up, you would not even consider it if you had my bad back. I used one of those B&D workbenches which was just the right sitting height, it even had a foot rest. Good idea that hoop support with your big hula hoop, my smaller hoop was OK without that refinement. You might remember seeing a picture of that split PVC tubing I hammered into the hole after each layer but before applying the mylar. The PVC outside was waxed, the epoxy I poured down there securely locked the layer in place while it was pressed against the hole. This allowed only one layer per day but I think was very worth while. My toroid transformers are very quiet, the only hum comes from the choke if the two halves are not clamped very very tight.
