I have modified the crown urn. Got rid of the boil dry protection and thermostat. Made one hole large enough for the wort return and left the other hole for the temp probe. It was a little bit oversize for the probe but it still seals and works well. Actually I think it is an old birko urn.
Hi all,
Have read the thread and am inspired to build my own clone. Was just wondering if it is best to get the main vessel with a sandwich base or not.
Cheers
