So can these mandrels use any tubes or just protubes??....I do not think that here are any protube dealers around where I live!!!..Most of the tubes I use are HMH
The stepped needles, as shown above, can indeed be used with any plastic tubes with correspondingly appropriately fitting internal diameters of the tubes you select, and the tube is simply snugged onto the stepped needle (which is held firmly within the jaws of any standard hook-vice), and the 'rear end' of the tube will be stopped at the matching stepped level, the rest of the tube being supported by the rest of the needle.
When you reach outer diameters of plastic tubing of 2.5mm or more (eg 3mm or 3.2mm [=1/8th inch imperial), then, unless the tubing wall is very thin, or the tubing is very soft (eg PVC), then such larger tubes may be more adequately held in a specialist tube vice, as HMH
There are other less 'elegant' needle solutions for holding tubes - eg the blindeye end of an old large single hook, various sewing, darning & crochet needles which may have the correct diameters & tapers (maybe worth checking your grandmother's, mother's, or aunt's sewing boxes for such!
