Here's one I did early last year.  Not the best sinew job, but functional and the bow is still shooting.   http://www.primitivearcher.com/smf/index.php/topic,18406

Thanks !

It looks similar to laying shingles on a roof.

And yet another question ...........how many layers of sinew need put on ?

Depends on the purpose for the sinew.  Normally I do 2 with the second layer maybe a little lighter than the first.  That lets you cover the places the bundles end.  I normally  don't run the second layer past the working portion of the limb.  In a highly stressed (ie. horn) bow you'd want more than 2 layers.

Thanks George .

I remembered I have 4 deer legs from 2 years ago in the shed high and dry . I was going to strip them and use leg bones for knife handles. They dried (lower leg)with hide still on . Would that sinew still be good ? Or does the ligiment need removed while fresh and dried like rawhide ?

You'll have to remove the rawhide to see.  I would expect them to rot if you left meat there, and any fat on them would go rancid.  However, if they dried to an amber color they may still work.

I got them stripped out and they are a honey color and stiff as a board ! Mice found them and gnawed one pretty bad ! I guess short pieces are usable too ? The hide seperated pretty easy .
