Before continuing with the spindle I needed to take care of my DTI.
Up until now it was all a bit Heath-Robinson and this was reflected in "variable" :heehee: results when it came to taper turning.
So first thing was to make a bracket for DTI, which would allow fixing of the clock directly to QCTP:



While at it, I have also checked my lathe (Prazimat from the old DDR)

My usual clock (with 0.01mm resolution) detected hardly any movement, so I used my new clock from Draper (0.001mm resolution):



Prazimat uses DIN55027 spindle head, size No3 and one can get chucks with this fitting on the back,
but they are rather expensive , so mine are all with usual backplate arrangement.

The reading on my Draper DTI was +/- 0.0015mm (total movement of 0.003mm) and just to check it I have tried my best DTI (with 0.0001" resolution):



The reading was below one division, roughly about +/- 0.00005" - 0.00008", with the total movement of about 0.00015

Now, the only thing I still need before setting the topslide with the DTI, is the straight probe for the front (instead of the usual ball-nose)
to overcome my usual difficulty of setting the clock exactly at the centre (usually ending with the taper not exactly replicating the original :naughty:)
