Good afternoon! I'm interested in trying to do some id grooving with the MNP. Could you send me an example of what this unit would look like? It would be on 1.5 1215 steel, .625 id bore, .812 groove dia., .25 from face to front of groove. Also do you use the normal offset page to change diameter? I currently use this to position a tap when I want to apply oil. This unit seems to give you more control. Thanks in advance for your help!
