I think the strength of the kreg joint in ply is because the screw angles across the plys not like straight in the edge screws. "hi lo" screws? those the ones that have a double looking type of thread?

|dsmylie||I have used the Kreg jig on several small projects and have been very pleased. Used in conjunction with epoxy sealed/glued wood and then filling the hole with a thickened epoxy I have what appears to be a bullet proof joint. 2 years latter there are no signs of problems. David|

Right on denise030
before you get to into whatever you're building, look into Hi low screws if you are going to be working with plys and softwoods

|ronspiker||As with any question the answer is 'It Depends'. It depends on what your use is. I do alot of woodworking, cabinets and furniture, so if you are making something like that then yes pocket screws work very well. I would also use a polyurethane glue like Gorilla glue also unless you plan on taking it apart. Another option if you are joining corners is to use dowels and glue, or countersink screws. I would only use screws if you are using SOLID wood. If you use screws in plywood it will delaminate, maybe not at first but over time it will split between the plys.|

|deniseO30||I confess! bought one of the K jigs today! first try gave me a perfectly drilled pocket and i joined to pieces of Marine ply in a corner joint. I was impressed!|

There are lots of woodworking joints because there are lots of applications. I like the Kreg setup for cabinet work. Once you're used to their jigs you can go pretty fast.
Biscuit joints, especially if you use two offset biscuits are surprisingly strong. But it all depends on what you're trying to do, what kind of wood you're using and what kind of environment it will live in.
Fine Woodworking did a stress test of woodworking joints a while back. You can find it on their web sites as a PDF. The results are pretty interesting if you enjoy wood butchering. taunton.com/finewoodworking/ToolGuide/ToolGuidePDF.aspx?id=31926
I say use whatever tool / joint will get the job done.

|soulesailor||In certain applications pocket screws are superior to biscuits. I agree it is more about the pocket itself and the application of use rather than the actual screw. If the SS pocket screws were way expensive I would just use a similar sized SS pan head screw.|
