@Gamma, now that's using your head. It must be fairly easy to tilt up for access to oil pan. How thick is that alloy? Can' t be too thin, otherwise it would crease the table. Care to post some measurements?
Sorry Tower just noticed your request. 4mm aircraft alluminium alloy. front plates are the same. Rear are a bit different to clear lumps and bumps. I was just wanting to keep it all horizontal to work on, but then discovered that I could move the plates around and torque my case bolts accessing both sides with the engine vertical.
