Submersible Build Log

Following instructions from Stachiw’s book, i got a tub of aluminium oxide and a tub of white tallow.   Never heard of them before, just got them off ebay.   Mixed a bit together to form a paste and polished with a cotton polshing mop.  I was careful not to get the port too hot as just a few seconds polishing creates quite a bit of heat.  I just went around once for a few seconds, then left it to cool.  Took a while to do but in the end, all ok.  Finished with cleaning with ordinary kitchen detergent.
