Weighing in at 26.7kg, one full set of cast engine cases. I weighed them as I wanted to know how much metal gets removed when I machine them. There’s a generous allowance for machining and they’re quite heavy, so hopefully I’ll get to under 25kg.

I had a couple of sets cast and heat treated, so I’ll machine a spare set. The spare can be used for a mockup engine with a barrel for dimensioning the frame. But that’s a way off as there’s plenty of machining to be done. Bob and I will work together on the Bridgeport.

Here we go!
