MAKING GROOVING BORING BARS

Making a group of carbide tipped grooving boring bars. CAD design is covered as is a method for repeatable location of the bars in making them and using them. Lots of grinding setups and non typical lapping techniques. The boring bar shanks are ground out of hardened dowel pins. #practitioner_of_the_mechanical_arts Paypal donation https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=W64WRAAGMA79J&source=url Support through Patreon https://www.patreon.com/ROBRENZ
