About this deal
The next question to ask yourself is: What kind of wood you are using to build your project? Softwood, hardwood, or plywood? When you know that, you can choose the correct screw thread type — either coarse or fine thread. The next question is: What kind of wood are you using to build your project? Softwood, hardwood, or plywood? This determines your thread type.
What does a self-tapping screw look like? Well, a self-tapping screw will have a little cut out at the tip of the screw – it almost looks like a microscopic router bit. This self-taping bit functions almost like a little router, as it cuts away the material, allowing the screw to get a good bite. It may come as a surprise to learn that the head of a screw plays an important role in your project’s outcome. There are many different styles of screw heads, and all of them serve a slightly different task. Third, consider buying a small quantity of each and then testing them on your specific project. Just because something is an alternative does not mean that it is the best alternative. By sampling several types of screws, you will decide which screw has the best performance for the best price. Conclusion
This ingenious fastening system simplifies all types of wood joints.
Stainless screws are designed for use in extreme environments that are exposed to moisture and corrosive elements.
Coarse-Thread screws are recommended for use with softwoods like cedar, pine, fir, etc. - as well as for sheet goods such as plywood and MDF - that are soft and not very dense.
Cabinet box technique
The important bits of the Kreg like drill guides, clamp etc are metal and the GRP bit of it hasn't ever been an issue. In fact if you make a slight error in setting and have the drill a touch too long its very forgiving as its not metal. Another one of the best doweling jigs I’ve come across is the Yours Bath 41 piece woodworking kit. It’s just about as simple as drilling jigs come, but it gets the job done without costing you much money at all. Creating a solid join between two pieces of timber with dowels and glue is an effective joinery method. But drilling accurate perpendicular holes is difficult without a guide like the Dübelprofi. It takes out all the guesswork when it comes to sizing as well.
