      Bazyle –

      Using two horizontal milling-cutter is not implausible because the smaller diameter ones can be mounted on a vertical-mill arbor.

      The method also has the advantage of neutral torque whereas using a single cutter can risk rotating the work-piece.

      That risk is greater if the work is held vertically via a threaded (e.g. Myford) chuck on a rotary-table. (As I once found when trying to mill a polygonal end using the jig-borer.)

       

      Julie –

      Rarity of arbor-spaces: a very good point but they are not too difficult to make to sufficient accuracy for all but the most exacting work.

      Apart from conventional turning from stock, an alternative approach is to use gauge-plate or similar. For some applications they could be rotary-sawn from stock mild-steel plate or sheet, then tidied on the lathe. The bore and o.d. are not too critical. Another possibility is a scrap machine-part, e.g. a bearing-race or turned collar, of the right size – I use such parts in work-holding on the mill.

        My only gripe with collet blocks the dont span the jaws of most (4 inch) mill vices so the horizontal/base of the block is only settled on one fairly narrow vice slide. I have made er16 and er11 versions that are longer for my Shoreline with small vice and they seem to sit on the vice base a bit more positively. Perhaps its only me but I find them a bit stingy on the material.

          Possibly kept short for when they are being used vertically on the smaller hobby lathes or in lathe chucks?

          If I do use blocks then I’m more likely to use the 5C blocks which as well as being longer don’t have a nut sticking out so you can loosen the vice and slide them out and away from the cutter quickly and easily. Th esmaller end of the block also lets you get in closer without hitting a large closing nut.
