I've got a Joint Genie dowelling jig which seems a well-made tool. Having used it with a few projects now, I'm convinced that the dowels I'm using (the 8mm fluted beech ones from the likes of Screwfix, Toolstation etc) are causing me a lot of problems come assembly time. I've measured the dowels with a vernier and they are generally about 8.2mm-8.3mm - for roughly drilled holes in chipboard I'm sure they wrok fine, but for joints with 4 or 5 dowels in hardwood or birch ply they take an extraordinary amount of force to close up. I can just about get a multi-dowel joint home with my strongest Bessey K-Body clamps and a significant amount of pounding, but there's no way the joints should be that tight. Can anyone else who uses dowels suggest how they get around this problem - is there a source of dowels I should be using which are more accurately sized, is it common practice to re-drill the holes with a slightly larger drill before assembly, or am I just doing something else wrong!
