@have2p good looks on this
thread. Good job on the aliens too, they look great.
One thing one could use instead of paper clips is masking tape. I rip off a piece of 1/4" & again rip that in half to make it 1/8" in size & tape up 3 parts of the cores. The drill end, the middle, & the end right before going into the swivels. I'm holding tension on the wires when putting tape on & sliding it up towards the swivel end once my wrap reaches the middle.
As for the wrap, I always under stretch & hold consistent tension on it. I won't do the whole length at once, rather I'll do the wrap in bursts to reposition my hand while still holding the same amount of tension on the wrap.
That micro chuck looks like something I'd
buy immediately. Where'd you purchase yours? Can you take a pic of the chuck itself?
