Brain cell woke up and 
. Found my small bit of angle iron 4" X 2.5" X 1/4" and mounted in vice to give the required steel "work-bench". cut a V in 2 blocks of wood and clamped column in blocks to angle. Bingo able to set DTI on end to take measurements. I could feel and measure 0.005" end float of inner column with end/clamp plate screwed down against the existing shims. Inner column moved fully up against upper thrust bearing and dial set to zero then gently pushed inner back down against lower thrust, removed end plate and added 0.005" shim to end plate and screwed plate in tight and DTI went to zero....success.
Thanks again Ian for getting me thinking along the right lines.
Non magnetic wood can be a nuisance at times
The angle iron can now be considered as part of the Nippy special? Its first use was making a new floor. With a second piece clamped in the vice with a suitable spacer between them to form a hollow on top a sheet of metal laid on and a 1/2 inch round bar over the hollow hammered along to gradually form the sunken rib seen in a Nippy floor. My panel beater friend's idea.
