Dowel pins can take some skills and proper tools depending on how they are used. I don't have great machining skills like a tool and die maker might, so...I kinda use them my way. I hate hidden dowel pins. For several reasons. Not so bad when they are tapered. When I install them myself, I usually make through holes when possible. Much easier to deal with if you have to take them apart again. I haven't used any tapered pins yet, but I do like that idea.
