Dave, nice touch with the ceramic foam displacer piston!

Why the sods in China filled the rolling pin is beyond me, the missus gets the hollow ones to fill them with cracked ice and water, keeps the dough cold so it doesn't overwork when she makes pies!

I would have thought IKEA would have something usable - God knows they make everything and the dog from stainless steel, or pressed chipboard!

I looked for another hollow rolling pin as suggested by MyfordBoy, but couldn't find any on eBay or Banggood. I never thought about Ikea.

The new displacer is pumice not ceramic, but not like the pumice that the missus uses on her feet!

Another lightweight and effective displacer piston is using the two endcaps with stainless steel coarse scrubbing wool between them.

Oh, and given that pumice is a volcanic rock, ergo, it IS ceramic.
