Re: Handmade Kitchen Table
I wouldn't use pieces wider than 6". The wider the elements of the glue up the greater the risk of cupping of individual boards. I have been given that advice while shopping for a jointer. Everybody said get an 8"+ one, but a guy who has been making furniture for a living for the last 30 years dissuaded me from that. He said he never goes above the width of 5" in his glue up projects. So I got me a 6" jointer, a really good deal, and I'm happy with it.
As for biscuits, when used for table top glue ups their holding strength is pretty much irrelevant as the glue line of the boards alone will give you more than enough strength. The value of biscuits in this is only for alignment. I use dowels the the purpose but I would have no problem with biscuits, except that a really good biscuit joiner is much more expensive than a comparably precise doweling jig.
I am pretty new to the whole woodworking hobby but I did some glue ups 18 years ago. Ugly and not so precise but they still hold (maple). At the time it didn't even cross my mind to use any kind of alignment such as dowels or biscuits. Heck, I didn't even know a thing such a a biscuit joiner even existed.
Oh, right now I work mostly with cherry and walnut.
