Post by: trail walker on January 29, 2018, 05:51:56 pm
so this is my first sinew backing project, in is on a 37 inch bow i tried to turn into a reflex/deflex shape. anyhow, my sinew is shrinking, making the reflex in the limbs uneven what do i do? would i just s tiller it back even after the sinew cures?

The picture is a really low resolution and you can't see it to well. There is an option to insert a picture from the web by using the Image icon below the Big Bold B. However you have to copy the "image address" not the image its self. So if it's your own image you have to store it in a photo storage service like Imgur, Photobucket, or google photos. I use google photos, but you have to create a separate album and make it public and share it from that album if you want it to work.

Yes, you will have to retiller the bow once the sinew cures out.

If you you may have added more to one side than the other, adding some the the lighter side will help, but you may end up trying to too hard to balance the sinew when simply tillering as norml is the answer.

Just let it go.  Leave it alone for a couple more months. You may have uneven curing/drying messing with you, or you may have to re-tiller (and that is not unusual at all!).   If you jump in too early on the tillering, you will just keep chasing hinges and flat spots until you don't have a bow left.
