Overdraw

(1/2) > >>

DC:
I'm thinking of putting an overdraw on one of my bows. I went looking for pictures and found none. I get the idea that it's a trough that the arrow runs in but the dimensions and how the thing aims at the string are puzzling me. Should it be aimed at the braced string or the full draw string or be wide enough for both. Picture   links if you have any, please :)

willie:
if it is aimed at the braced string, does it not align with the string at full draw?

DC:
Not quite. The angle between the arrow and the bow(looking from the top) gets closer to 90° as you draw the bow. I think I said that right. If you watch the tip of the arrow as you draw the bow, the tip moves to the right. Mostly at the beginning of the draw. That angle :D

DC:
I was thinking of the thing as half a tube but I guess if it was flat it wouldn't matter. I've got that picture of Karpowicz's PVC tube stuck in my head.

PatM:
You must have not looked very hard.  ;) Typically they were a piece of aluminum  u channel or similar screwed into the side of the arrow area.    They are just put on straight in the side and the  width of the structure and a rest of some sort provided clearance.  They don't need to match the angle of the drawn arrow.
