    When you look at the fitting in various different limbs, you can see that the "U" of the slot doesn't contact the bolt. I guess it kind of has to be that way, since you can adjust the angle, and the detent clicks into a fixed place. So the bearing in that direction has to be on the dovetail (and slot end). The main load bearing, on the other hand, is on the bolt and the contact point between the limb butt and riser pocket.

    Hi dvd8n, I totally got wrong what you wanted to know. I was explaining how the limbs put stress on the tiller bolts and dovetail when the bow is drawn, or even just strung.
    The answer to your question, now that I see what you mean, is that the dovetail , in order to work , will jam tight. If the tiller bolt stopped the movement first, the dovetail would still have slack in it and the limbs could move side to side.
    It is no good, however ,having the dovetail fitting tightly if the butt end is loose at the tiller bolt. The slot in the limb at that end is parallel so it should be a snug fit in all positions, with no side to side movement. The depth of the slot should be sufficient that the slot doesn't bottom out on the bolt.

    Not what I call a doves tail. The picture shows slot that the location lug passes through on the way to the brass limb alignment adjustment piece where the limb lug is located. There is no way that is shaped like a 'doves tail' The sides of the slot are parallel whereas the doves tail has sides that are fanned out. After the limb is correctly located this slot's function is over. So, no dove tails. The limb is held by the 'U' shape cut in to the end of the limb and the limb bolt and the lug locating in the brass alignment adjustment piece in the riser.

    They pictures shows them not to be parallel. They *are* fanned out.
