Title: Newb question on backing
Post by: Catkinson on July 28, 2021, 06:54:03 pm
Built a couple red oak bows now and have enjoyed the process. Working on a hickory board bow  now. I'm almost done with final tillering and was wondering if I can back it now or is it too late? Basically I’m not liking the string follow and set that it has taken. Thanks for the help in advance.

You might consider building a reflex form and heat treating the belly on your form. It will add some weight and reduce/eliminate string follow. Hickory loves heat treatment.

Generally I would plan a backed bow from the get go. You can add a backing, drawing the bow into 3" to 4" of reflex at glue up. Hickory, maple, elm or bamboo can be used for the backing. OR, you could start a new bow using the knowledge you've gotten up til now and give this first bow to a someone else, a kid maybe. OR, what Will said.

As has been said Hickory loves heat treating. It has to be done before glueing on a backing. Unless I just wanted a backed bow I would and do just clamp both ends to a flat surface with a block of wood under the handle. This will give you a slight reflex about half of which will pull out.
With a good toast color heat treat you could end up with a straight bow after shooting it in.

I’ve had good luck with this method. Your mileage may vary.

P.s. the tiller will need to be checked and more than likely a little work after heat treating.

You can run into problems trying to heat treat an already tillered bow. It ain't all a bed of roses :)
No point backing it once it is already done. You would add a bunch of draw weight and have to start tillering again.
