I used 12 regular 8x8x16 blocks....the cribs were 8ft x8ft roughly, and 24 logs on one and 332 on the other...and brushed thick in each....they both melted through sank right to the bottom this past weekend.

I tied these all together with poly baler twine and square lashings (like building a raft).

Best regards,

MT
