When I'm centring bores on the vertical mill the sensitivity of my lever DTI is a pain to start off with (1/10th thou etc). It would be easier to use the half thou sensitivity of the plunger DTI as a start. In days gone by I've seen attachments that fit a plunger DTI to enable it to work in different ways (eg side movement as per a lever DTI or downwards movement etc). However when I want to buy one I can't find it. Does anyone one know of a supplier?
Thanks
