John, If you have a well fitting register, as long as you don't make the holes larger than the bolt heads, then you can most probably rescue what you have done. The bolts are only there to hold the chuck onto the tight fitting register, they take no part in the alignment of the chuck. You could go even larger with the use of some thick washers. John BTW, the way I did these was rather a long winded one. Normally, when you get a new chuck, it comes with a sheet telling you all the dimensions. By using the PCD of the bolt holes, I could have just as easily have put a centre pop in the centre and used spring dividers to scribe a circle and then divide it up into 3. That would have been plenty close enough to get onto the drill for the holes. As I said before, the holes are there only for holding the bits together. |

Great job on that John. Will be a very useful reference for people. However, 0.0015" is approx. 0.04mm :poke: Stew, I would take it back! :lol: :lol: Nick |

Sorry about that Nick, it must have been one of the days I used my toes instead of fingers for counting, now amended. John |

I think I've been Nogging the Nog in this Saga :lol: :lol: :lol: :lol: Anyway picked John up this morning for a boys day out down the scrap yard, and he returned the completed backed plate to me and what a great job he's done of it thanks John :thumbup: This is the adaptor with the chuck, I can now take any of my chucks:- three or four, self centre four jaw, or even my face straight off the lathe with the job still in place and put it onto the indexer and know it will be running true. A happy :D Stew |
| NickG:
Brilliant - well done John and Stew. Now, where did you put those chucks? :doh: |
