DTI holder for lathe toolpost

(1/3) > >>

Hi Lads 
             Just made a small gadget that will make life easier, its a dedicated holder for a DTI that fits on the lathe toolpost. Nothing fancy but seems to work fine.
  Its just a bit of square bar that fits into the quick change holder, I drilled and tapped it M6 at three points along the side and also on the end.
  To space out the DTI so it clears the holder I had some stand off type bolts, its the sort of thing that is used to mount a circuit board or panel so its stood up off the base, all they are is a tall nut with a stud sticking out one end. I had 4 of these they just happened to be perfect size to space out the DTI and the last one acted as a nut to nip the lug on the DTI, to make it easier to get a hold of when tightening I screwed a M6 plastic knob into the nut.
  I think all should be explained by the photos.

 Mounted in this position its good for bar or the edge of a small disc type item , if you have a larger disc you run out of travel with the cross slide but you can then mount the DTI in the rear nut, in practice you will probably have to remove the front nut so it will give clearance for the DTI.


 
 If its mounted on the end position its able to indicate the face of a disc.





 I actually drilled three holes just as it was set up but I don't think there is any need for the middle one.





 Its very quick to use , nice and solid with no faffing about with mag stands and all you need to make one is a bit of bar and 4 of the stand off nuts, then drill and tap 4 holes. If you wanted a smarter looking one or just wanted to make it into a bigger job , you could turn the spacer nuts and knurl the end etc.

  Cheers Mick.

Very neat mick, you could  also have a Finger clock  in the same holder on the other end for dialing in on an internal bore ect.

I have sworn so many times to bin the magnetic holder I have, just to force myself to make some mounts for the  lathe. This will be my next project after my lathe is back together, Mick, Thanks! :beer:

Very nice design; had made something similar some time back but of a different design to yours, you've got me thinking of improving on mine now, whereas I turn the dti round in the holder & place the holder on the front fitting for face reading your method seems a better set up.. thanks for the idea.
