The aluminum is surprisingly clean with almost no sand inclusions, which saved me a ton of cleanup time on the lathe. These castings are machinable right out of the box for the Panther Pup build.

I’ve been machining these castings for my Panther Pup and the consistency of the aluminum really surprised me—minimal scale and clean parting lines. Each blank took far less setup time than I expected, which is a huge relief for a hobby build.

The aluminum blanks are beautifully clean with no visible porosity, ready for the lathe. I've already roughed out the cylinder and crankcase, and the material machines with a nice finish.
