G'day Willie, and welcome to the forum.

Most response seem to be dowels v biscut v spline, not offering any brand.

Like Harry, I cannot recommend as in Australia...

denniswoody Biscuits allow a sloppy fit which is nice is certain applications like edge gluing. They do not provide as much strength as dowels or tenons so cannot be used in high stress applications like chairs. I have never had a problem with swelling but apparently it is something to be careful about. A biscuit is not the equivalent of a spline or floating tenon and should not be used in place of either.

roofner My vote is also pocket holes but it is really what your most comfortable. Gluing up panels I use Dowels or be lazy and buy panels already glued up.

Herb Stoops The first one I had was the PC in the 90's. It was excellent,we used them on the job extensively. now I have a Ryobi, and it does good too, I don't have occasion to use it much.

Cherryville Chuck Although biscuits are designed to expand in the slot, the slots also have a bit of play in them. So it's a s much the glue causing the swelling as any other factor, which means that a spline can also cause swelling. Experts advise to wait a few days after gluing to allow the water to finish evaporating out of the wood before sanding and finishing. This lets the swelling go down so that it isn't a problem. I've read of people who sanded right away to level and then wound up with a dished surface days later.

RainMan 2.0 Harry, I never even thought about using biscuits on a mitred edge . I have a Dewalt biscuit cutter and will certainly try it one day .
I’ve heard some materials expand to much with biscuits and glue ?

On something like a table top or where you need to edge join 2 or more boards with insurance that they won't pull apart and have the joint crack then I would also use splines. But on something like a picture frame miter where you don't want the spline to show then biscuits are hard to beat. Even if you didn't care if the spline showed, a biscuit joiner is much quicker. The biscuit joiner is also good for joining something like an apron to the underside of a table top if you are working with composite materials where there is no expansion and contraction. They can be good for joining melamine panels together in that way too. Melamine doesn't hold screws well so I like to use biscuits and dowels to reinforce joints.

So, in my opinion at least, biscuits do have their place in woodworking.

DesertRatTom I have and occasionally use the Porter Cable. Nice machine, pretty fast to use.

harrysin Being in Australia I can't suggest a brand for members in America but I can state that since I bought a cheap GMC (no longer in business) biscuit jointer I have never used dowels, which require careful measuring and in my opinion many of the dowelling jigs on the market leave a lot to be desired. Biscuits on the other hand require no measuring and give perfect alignment, a surprising amount of strength and the adhesive does the rest.
