Misc. Analyzing Oscillations of a Metal Semi-cylinder

Summary
I'm unsure where I might find such an object for the precision I'm looking for. Ideally, it'd come with known dimensions (density, mass, length-dimensions, etc).
I want to replicate the rocking semi-cylinder problem from analytic mechanics, but don't actually have in my possession a nice, solid cylinder to rock. I imagine my professor likely made his, or found it somewhere in Estonia. If anyone can point me to place where I might be able to find one for purchase, that would be nice.

I would suggest contacting a machine shop that does shaft work. They should have precision shaft material that can be cut to length and split. The key will be what tolerances you can work with.

Search for "half round bar". For example, https://www.mcmaster.com/half-rounds
You might have success finding something off-the-shelf depending on dimensions and precision required.
