The biscuits are compressed and swell when wet by the wood glue. I see no reason why more than one species would not work. Biscuit joiners were invented by Lemmelo who is Swiss, I think. Beech is popular in Europe, so the biscuits that first appeared were beech. I guess somebody found birch more available or cheaper. There are few things that can only be made from one species. Just me rambling. If the birch biscuits are no good, please get back to us.

It may be a while. The glue ups worked fine. Have to wait and see if they fail in use. Can't imagine that big companies (mine were sold by DeWalt) would sell them without checking out test results......based on all the law suits these days.

No disrespect, N/a but my preference is to just not eat the grits. I’ve tried them many ways and I just don’t like them.

Coming back down to earth, I have only ever been able to purchase biscuits made from Beech and have never had a problem, even with this bookcase that I made long ago as an experiment using biscuits.

+1 on the biscuit jointer, used it last week to make multiangle floor wedges. PVA'd all over the place and then left in a former overnight.
