| Lathe chuck backstop for dummies |
| (1/2) > >> |
| Gerhard Olivier:
Thanks to Bogs I now know whan a backstop does and how it works AND I WANT ONE I dont have any morse taper blanks and my topslide travel is to short to make one without a lot of luck involved. The other way mentioned looked like I would be able to manage So I need a expanding collet that fits the wrong end of the headstock spindle. 25mm MS + lathe + +Slitting saw = This has a 12.5mm bore right through and a low angle taper at one end Then the Tapered locking bolt needs a Outer thread 12mm *1mm pitch and a inner 8m thread And ready for parting ( taking it out to the garagde and cutting it with the hacksaw) Parting noise wakes kids The setup on a piece of 8m studding just needs a 12mm *1mm closing nut and some accesories - like delrin spacer to keep it from rattling and maybe a flat end for the material to rest on. Enough for tonight Hopefull more tomorrow Gerhard |

HI all Thanks Bogs , Stew and Im not sure what it is called its a spindex takes 5c collets and Im working it with a 5c to er35 adapter.I got it cheap at the mod eng show. Just need a little knurling and some small bits then I can start with the saddle stop- maybe do a multy stop rotating index. Gerhard |
