all smiles here now, I decided that I didn't like having a spare z axis on my gs900 3dro so with brain in gear ,I decided that I would take the dti to task and used the z axis as my dti
heavy magnet out of a speaker ,tapped a 8mm hole through the centre, attached a supplied bracket to the magnet with 8mm ss bolt, two 6mm screws hold the scale to the bracket. holes a bit of a problem to attach probe to end ,
a broken needle file shaft , rounded on the linisher did the job and attached by a 5mm screw from underneath to a 7mm shaft with a 3mm hole in it to take the probe . a weak spring to keep it against the work and pluged it in to the dro z axis .got a old shaft and put in the 4 jaw turned to jaw one read dro turned to jaw three read dro divided the difference and adjusted jaws ,
same on jaws 2 and 4 adjusted work to settings hey presto in the middle easy as very happy chappy , only problem is the amount of effort to remove magnet from the bed
