    The owner wants to throw "cubic dollars" at a project. This started with me having to grind a tool for cutting the ring pack grooves. .0375" wide with a 3* draft on the trail and side reliefs at 1*.

    Then the fun starts... Designing/modeling. This is the roughing portion of the part as it runs through the simulator. The cusps are just from the tool's stepover. That cleans up on the finishing paths.

    Op1 lathe parts off the machine. OD is to size along with the ring grooves.

    Running the program through the machine sim. This is the roughing portion. (why there's cusps in the corner fillets. Those cleanup during finishing

    Finishing. All that's left now are the drill ops for pin oiling and evacuation off of the oil control rings. The slugs are going to be left "long" on the crown side so that they can be sized accordingly on the deck height after the block is resurfaced. (were not part of any block work)

    Sunday projects. . .fun stuff.

    YOU had to go there, lol. My douchebag friends have already started. . . They all promised to buy me a lemon tree so I can pee on it every morning in my front yard. I imagine a pile of used-up beer cans will show up as well. (Burt Munro)

    Fuckers... loll.

    -These slugs also happen to fit a certain model of Indian and the orders have already started.
