got a bug report for you using the newest 1.4.2 version. When using these in conjunction with a peat fired engine it seems to like putting the peat bars in the waste product (ash) slots! Other than that everything looks good
Forestry/BC bug, not specific to my pipe. Any pipe will do this.
It's a little toy block. Connect pipes to it, when it receives items it puts them into a random attached buildcraft pipe. Not very useful with BC only, but if you have other mods with pipes, it can be used to translate between pipe systems without a chest+wooden pipe+engine setup.
