I am making a cutting board along the lines of the ones in the SMC tutorial. One of those has the maker cutting a narrow strip out of the middle of the glued up cutting board and flipping it end for end and gluing it back. Is this end grain gluing strong enough for a working cutting board? I don't remember the author/maker saying anything about any kind of splines, biscuits, dowels, etc. Will just a good glue line cut be good enough to glue together?
Thanks for your help.
