I thought I'd share what I'd been working on lately. I made a cast aluminium manifold for my buddy's race car. It's a watercooled VW motor and this manifold will fit a single Weber DCOE side draft carb to it. This is my first attempt at metal casting, I did everything from making the pattern and core to melting and pouring the aluminum. Here's pic of the second one that I cast fresh out of the sand, at the point this picture was taken, the gating had been cut off and the core knocked out, nothing more.
