Here are the two bows I'm more or less trying to duplicate:
In both cases I can't tell from the photos whether these bows have a sloped table forward of the area where the string rests, which is where I'm assuming the slope would start. Question is, do these bows slope down or would the quarrel rest stick up above the flat surface of the table slightly giving a ramped rest of sorts as Geezer has mentioned some bows having had? How would you make these tillers? Flat from the nut forward, or some downward slope?
