Only managed 1/2 hour on this today but cut the MDF for the moat. Tomorrow I'll glue it together and seal it, thinking of sticking it to the steel with silicone sealant which will also act as a sealant to stop (hopefully) any leaks as I don't want a repeat of last time where despite my best efforts (obviously not good enough) I had leaks at some joins.

If I can get it together and sealed then I might go for a pour so it starts to set over the weekend. Whatever happens I'll not be rushing this....lesson has been learnt from last time :)
