I hesitate to bring up a problem in a public forum, but I think it may be my fault, so need some input. My traveler does not seem to rotate around a fixed point - the shank of the hook is in one position when I insert it in the vise, but when I turn it upside down it is a good 1/4 inch lower - this makes the thread jump up and down when wrapping and it doesn't go on even. Does this make any sense to you rotary tyers?
