Topic tags/keywords: biscuit joiner question joining

I am in the middle of building a library stand and coming down to the end of it where i have to glue up the 24×18 table top. now the plan dont call to do it with biscuits, but i am not entirely sure if using biscuits will in the long run keep the glue joints from separating. do you really need a biscuit joiner for this type of glue up?

I’m not one to poo-poo biscuits, I think they really have their uses. However, one of them is NOT edge to edge long grain. Other than alignment, which is useful, they add little to those joints IMHO.

Biscuits add more glue surface and make your joint stronger. It is a small surface and as a library stand I think you can get away without biscuits.

I use biscuits mainly for alignment. They will add a little to the strength but on an edge to edge joint you don’t need them for strength.

In your case biscuits are simply an alignment aid. The glue joint, if properly done, is stronger than the wood.

I can’t say I hate biscuit joints but I will say that I own a biscuit jointer that hasn’t been used in probably 15 years.

I prefer dowels, splines, and mortise/tenon for alignment and strength. I never found the biscuits to be that helpful with alignment.

I thought I needed them when I was a rookie and didn’t know any better. I sold my biscuit cutter…on the rare occasions I think biscuit will help, I cut the slot with a router.

I’ve used biscuit joiners quite often with good results. Not sure why there’s such a negative vibe about this tool. I agree that it’s useful for alignment purposes, but it also adds quite a bit of strength to the joint. Although it’s rather eyeglazing, there’s an interesting article on the web that conducted some experiments and goes into great detail claiming “that the “as tested” biscuit joints had as much as 80 percent of the strength of a mortise and tenon joint.” That’s pretty impressive for such a simple procedure and sure warrants consideration.
