Thin section parting tools

[don-tucker]

I have one of the 1/16" parting tools below, though you would not want that much blade hanging out. I don't use it for anything over 5/8" dia but its ideal for small work. The blade is tapered top to bottom and held at an angle which gives a few degrees of positive rake so you only need to grind the front angle

Don't you need to grind side clearance Jason,from the tip back a degree or so.

I've only just got back here after the Downtime, I've got some catching up to do.
Over on MadModder I briefly described the completion of my QCTP for the Sieg C3. Part of the deal were Parting Toolholders, I use 0.040" and 1/16" x 1/2" wide parting blades from LMS. They are fitted in dedicated toolholders "upside down" and parting off is done in reverse. Parting off is now a simple, no drama process, where it used to be very much heart in mouth stuff.
