set prone ash
« on: September 03, 2011, 02:16:54 pm »

Yup, wide, flat, heat treated belly.
While you are heat treating, you can put in a bit of reflex (which will prob pull out during tillering)

Steam the center 16-18" of bow and set the handle back at least 1". That area wont pull out and it will add some "zip" to your bow even if the limbs follow the string after shoot in time.

It will add at least 5-8#'s of draw weight as well. Plan for that if you decide to set the handle back. Setting the handle back 3/4" moves the limb tips back a few inches.

Ditto what everyone has said to this point, I would add that a good sealer (maintained) and ensuring the wood is at a low moisture content to begin with will help keep set in check...I occasionally put my 'white' bow woods in the hot box to keep the moisture level down...I'm in the Missouri 'three rivers' area where humidity is high and this preventive measure really seems to help.

If you set it back in the handle area it will increase stress on the rest of the limbs which won't help you get less set. It may mean that the tips sit a little further forward (all things being equal!) but the extra set which will result from the increased stress will mean that the wood has lost more 'spring' than a straight limbed bow.
I've made lots of bows from ash and in the beginning I came to the same conclusion that ash is prone to a lot of set. Heat treating and low moisture content is the key with ash. It's perfectly possible to make low set ash bows if you get a piece with low ring count per inch.

I should have explained myself better. My comment wasnt regarding less set, just ways to keep the draw weight up and the performance in a bow that follows the string due to set.

The best ash bows I've seen are 2" wide and 1/4" thick with big recurves!
The wood was from large dia. trees so that the back had allmost no crown.
Thinking of doing one myself since our trees will soon be gone! (ash borers )

Ash is much stronger in tension than compression, i've found the exact opposite! Smallish diameter staves with a good crown and flat belly even out the properties somewhat  ;)

I've only made one bow with ash.  I have to say I really like the wood but I don't know it well enough to comment.  All I know is my bow took a good amout of set and I lost quite a few pounds in draw weight  (8lbs) when sanding and shooting in.  I was a little surprized to loose so much but I had never used the wood before and now I know to plan for it next time.   Glad you started this thread.  I plan to make more bows from Ash in the future...

Ash can chrysal fairly easily so you don't want to put too much reflex into the limbs
