Larger die holder
Why not make one use a 2mt shank with a parralel running from that to a die holder cut from mild steel fitted with two locking grub screws, suitably hollowed for longer threads but easily adapted to accomodate your short threads. This in a 1 inch version is an exercise at TAFE Colleges here downunder. The exercise is aimed at producing an accurate no 2 morse taper to parralel shaft. The rest very straitforward. People with C and C capacity a walk in the park. Ask Johnny C and C for his advice, there could be quite a market for them. The unit for sale at 19 plus dollars could be easily adapted to a number 2 morse taper shaft fitted with a sleeve to accomodate the device with a slip fit to use in the Tail Stock of your lathe. When I modified the mandrel for my Pen Wizard I lengthened the 1/4 inch thread considerably either end accurately and easily using the one I had for many years. I cut the thread by hand movement on the die holder that is knurled on the outside, it cut easily,accurately and in full control moving the shaft in the no 2 morse taper every little while as the parrallel shaft allows some travel before take up. In this country bear in mind and I have no doubt in yours people are not able in commercial engineering shops to do this cheaply with labout costs as they stand today, try to arrange a quid quo pro equal swap with a pen. A man a total stranger to me beforehand made me a live centre using hard steel to my design by C and C and said all he wanted was one of my beautiful wood pens (his words I quote), since I make them from Slimline Kits for me it was confirmation to me of a favourite saying I have. THE POWER OF A PEN.
Have fun Peter.
