After a full week of playing with it, my conclusions are that it is a little on the delicate side, fine for tubes, too much of a faff for heel turn and thus socks. The latter is because the needles dip before rising and if the yarn is not under the hook, they drop off. So every individual held and/or wrapped stitch has to be picked up and re- placed before it enters this area, which starts about 8 needles away from the knitting point. This does not happen on stationary cylinder machines. Advised not for the under-14's either, so that is a big disappointment as well for showing in the museum.
"Tubes" - by which I mean scarves, snakes, glove puppets, handwarmers, armwarmers, leggings, Celtic knot cushions, Comfort Dolls, gnomes, owls, bags, mittens ..... there is an endless list of things that CAN be made.
3D printing is probably the way froward, but some alterations need to be made, not least of all the fixing clamps.
