Top Half of Bow Form Question

[EzellH93]

I understand that the bottom half needs to be pretty much perfectly smooth and 90* to the side. What about the top? I cut out the riser pattern and it's 90* but not perfectly smooth. I'm wondering how important the upper half is since none of the lams actually touch this part but rather the hose does.

As long as it will close the gaps in the lams when the air hose is  inflated it good.

Perfect is always better but better the bottom is perfect. As long as your gap is right it don't have to be smooth.
