  I bet it starts slowly going back about now that it has stopped deflexing. Maybe a weeek r two and it should go back into reflex. I would not reflex it now because the sinew is allready layed down and is not designed to compress.

Did you size the back the day before with hide glue mister?
PD may have been onto something!

I sized it, but only a couple hours before but it was dry since I had it in the room with the wood stove after sizing.

I think this might be the real issue. It is very dry in here and cold outside. I don't have a moisture meter but it must be real dry and then putting it in stove room. I wonder if I didn't let the glue absorb slow enough when sizing??

Yeah, I think you're probly right. I'll leave it alone and see what happens. Kind of an experimental bow anyway.


Brings me to another question. I am scared to tiller it when time comes cause it's too dry and it is ERC  ::) What to do what to do??

Sizing requires more than one application of glue as far as I'm concerned.
What I will typically do is apply sizing coats of glue until the back is shiny with glue.

Once dried the sinew adds a lot of integrity to the ERC. Take it slow and exercise regularly...gradual at first then more and more.

Does it gum or gel up on you? Do you sand between coats?

It does not gum or gel as you're applying it. It can easily be painted on with a foam brush.
No, I don't sand it between coats,, though I do allow plenty of time for each coat to dry before the
next is applied.

  Mike, it won't keep going. A bow at full draw is only stretched less than 1%. A very small amount of moisture on one side of the bow only will cause that wood to slightly expand. It will shrink right back up. If the bow was put into reflex before the siew was applied I would agree with you but I would not reflex the bow with wet sinew on it. It will shrink as much as it is going to shrink no matter what position you put it in.   I would maybe slightly reflex it but not much.

Haha, hey doobie man... maybe your putting the sinew on the belly instead of the back? Jk of course. But I wonder how an upside down erc with sinew would do?

If you did it backwards, try it like that. Use the sap wood as the compression wood, and be sure its flat and not crowned. Id love to see an ERC built inside out.
