can anyone help with restoring the brass data plates from my Granville Senior lathe???,the screwcutting data plate is an etched brass plate,the depth of the etching is very shallow,rendering the data almost illegible,l am very hesitant about applying paint and then sanding as l could very well lose some or all of the data,l have wondered about using ink instead of paint,ink being a lot thinner than paint,l have been quoted a very eye watering price to produce a copy,but l cannot afford that,so,can anyone offer any advice???,l can, of course make up a card copy and laminate it,but would like to have the brass plate back on my machine,thanks,jack.
