so a few glue used on adam's sinew backing job?
maybe this topic will be top secret ,
these sinew are white, lots of sinew back bow is yellow or a few white , the white sinew is the case the glue not into the sinew, so that sinew strings is not so strong conjoint , but these bows works very good, what draw weiht of these sinew?

I don't agree with you.White sinew doesn't necessarily comes into being just because a lack of glue.
when I glue sinew with hideglue or glue from fresh water fish bladders,the sinew is black and the sinew is white if it does not absorb enough glue.
At the same time,some bowyers use glue from certain sea fish bladders,the sinew will not be so black.
I don't think it matters whether the glue is made from sea fish bladders or not.

Here is the top secret: I normally file and sand the sinew on bows to make it flat and even. Then sinew becomes a little fuzzy and white, as you can expect. Without filing, sinew is nearly transparent and yellowish as usual.

I guessed that after viewing the picture. Would you then apply a final glue coating after sanding the limbs smooth?
Yes, before covering with leather or bark.

how does sanding the sinew affect the tiller ?And what do you do to fix the tiller?
Ralph, it does not affect the tiller, because I do it before the tillering process. By filing sinew, I only remove very little material, probably no more than a fraction of milimeter. This final thickness, after filing, is planned from the start anyway.
The flattening sinew can be done by rubbing with a round dowel. Cem may tell you more about it, I have not had much success with this method.

As I can see,your bow is very thin.The bows that I made look very fat,though they are only 12mm thick----horn 5mm ,bamboo 4mm and sinew 3mm.
How can it be like that?

on this hornbow the first layer sinew looks transparent and yellowish,adam, when you use fings press the sinew back , what feeling of your fingers? soft?punky?stretchy?
I can't remember which of the bows is on this picture, it could be lighter weight.
When the sinew and glue are dry, the layer is hard. Not soft or stretchy.
