I used aluminium for my displacer David, think it's pretty standard to have a hollow aluminium displacer with a very thin wall - same as hot cap to minimise heat transfer.
Good work.

If you can Dave, get the whole inside surface sand blasted. Any little pockets of weakness like that will soon show up.
Then a bit of JB Weld or even soft solder will take care of it, just make sure you neutralise the flux afterwards.
