For setting out joints see the paper 'Basic Setting Out 1' here and follow the articles through. When you have cut down the shoulders of a tenon properly, removed the waste of a halving and chopped out a mortise all these skills are repeated for most of the other types of joints. Remember to cut the shoulder lines with a sharp knife and 'vee' it partially to get a good joint. A tight joint is not needed, just fitted well. If it is too tight the glue will be forced out and any minor imperfection will throw the frame out and into 'winding'. There are numerous 'rules' for beginners and improvers to learn and at times it seems like there are too many. They are not my rules. The 'rules' however, are the techniques handed down as the most effective way of doing things. They reduce your error and allow you to work more efficiently and above all - safely. Later when you have learnt the techniques and you work effectively you may fin...
