Cruder hide glue actually seems to shrink  more.

Wrap it with cloth and place the bow in an cold dry area.

Basement is the coolest area.  :-\

evaporation is affected by air flow and heat.  No "wind" to speak of. 

I hydrated the sinew in water then dipped it int he glue.  Should I not have used the water soak (2-3 min tops).

Well I've chased around several small gaps and clamped them out with tb3.

Now the biggest one?  Should I clamp and squeeze or fill with something?

Also I have a few tag ends that stick up.  What to do about those?  If I did another course with just wet sinew would it stick? Or is the damage done?

Use 220 grit and sand it lightly. Then wipe down with a barely damp cloth. If any more bits lift up, sand again and repeat with the damp cloth.  If it is nicely smooth when dried again, thin a little bit of hide glue down until it is really runny syrup consistency and use a finger to fingerpaint a very thin coat.  Done with the hide glue and sinew...start thinking about your sealing coat.

Second coating down. 

This time there doesn't seem to be any cracking going on......or only tiny amounts.

When I snake skin this is it necessary to fill all the little gaps and valleys?  I planned on sanding or scraping a bit to help level it.

you dont have to have it that smooth to put on the snake skin,,, every thing I have read suggest that sinew will make checks in the wood as it shrinks,, I think it is pretty normal,,, I do experience a bit of checking, I usually leave a coat of glue on the belly side and that seems to reduce it,,

The new layer of sinew has been on for about a week.  It feels and looks dry.  How long should I give it to be sure?

a couple of weeks,, and when you put the snake skin it will introduce moisture, ,so you need to wait again till dry,,
