I've been having a difficult time getting mitred mouldings to line up exactly. The way it's explained in the Joiner and Cabinet Maker is to draw the line, cut slightly on the waste side, and then plane it down. Planing odd and thin strips of mostly end-grain at a strange angle is not trivial, even with a freshly sharpened low-angle block plane, but this is what I have been trying to do. I invariably end up taking off a little too much, which leaves a piece critically short. Even a hair's width shows as a faint dark gap. I have gotten good at filling and hiding these cracks, but those are not the skills I really want to build right now. I realize that practice is the only answer, but if you have exercises which have helped you, or things to think about while cutting mitres, I would love to hear about it. I have a Stanley metal miter box, but I think it does more harm that good, since it has a bit of slop. I'm tempted to make one of wood, but that depends on the ability to cut a perfect mitre to begin with, which sortof defeats the purpose!
While my dovetailing has coming along quite nicely, and I am able to saw to the line at most angles, there is sometime about the narrow moulding which has me tilting the saw in an odd way. It usually looks great from the front and top, where the line is, but towards the back it goes awry somehow.
Any tips or considerations left as a comment here will be most welcome. Thanks!
