yes, mine sank. I still soaked the wood for ~3-5 days in very hot shower water in a large tote (can't remember how impatient I was) to get some of the tannins out and allow it to sink better. Way too large to boil. Two sank right away and one required a little teasing. Malaysian is pretty dense wood (looks like teak). It took me forever to hand saw through one piece. I was ready to run for the chainsaw.
