I recently aquired my Myford M-Type. It has only one vernier scale and that is on the cross slide. In the current issue of Engineering in Miniature, there is an article on fitting a linear scale to a milling machine. The author talks about and shows a picture of a digital readout (like on a digital vernier) which he added to his Myford tailstock but gives not details on this.
I am thinking of mutilating one of the cheap (sub 10 pound) digital verniers that are common now and fitting it to the tailstock but I could do with some guidance. I can imagine how to mount it to the tailstock body but am not sure how to attach the moving part to the barrel.
I'm thinking of making a collar to fit over the barrel. The collar could be held in place with a small grub screw but my concern is that the barrel rotates back and forth slightly - the collar would also then rotate and cause stress on the digital scale. I am probably not explaining my concern very well .
It seems likely that this would have been covered in a magazine at some time - does anyone know where I might find some relevant info.
If this worked well then I might consider adding similar scale to the cross slide and perhaps top slide too...
Many thanks Martin
