I've used sand very successfully to avoid pipe kinking when
bending - although not for inductor winding. With larger coils and
heavy wire I anchor the far end and wind the free end onto a
former, walking towards the anchor. This lets you use body weight
to keep tension on the wire. I don't suppose you'll get much
tension into quarter inch tube, but maybe better than nothing -
assuming the tube is soft enough to wind that way.
