Single Yoke Measurements

[Roscoe]

I’m currently building a single neck yoke for my 3y.o. Holstein steer. He is pretty tall (around 16 hh) but has a small neck, only 7″, but needs a long bow.
Tillers have in their plans the drop for the hitch point for the single yoke at 0.4 x bow width, for the (double)yoke once at 0.4, once at 0.6 x the bow width. Does the relation from bow width to drop change, if the relation between bow width and length changes?:confused:
For example: my steer would have a drop from (7″x0.4) 2.8″ drop. A limo with the same height with a bow width at 11″ would have a drop from (11″x0.4) 4.4″. It would be a significant different caused just by the thickness of the neck.

The same thing for the length of the beam: Tillers use by their blueprints 2.75x the bow width. But I’m afraid that the traces will rub on his belly, when the yoke is only 19.25″ wide. I thought I’ll make the yoke the same length then the singletree, 30″.

Any thoughts?
