Hi Nathan
                  I recently had a go at making a 100lb ash warbow but undershot the weight and ended up with 85lb at 31 inches. The results were very encouraging though and the set was only about ½ inch. The ash I used had growth rings of about ¼ - 3/8 but the density was about .7 . The cross section was almost rectangular with well rounded corners. Belly was heat-treated and bow was 74 inches nock to nock. I intend to have second go at a warbow, but at he moment I am making an ash 50lb target bow. Hope yours goes OK, keep us posted.

Was not happy using temporary knocks so I went ahead with the horn knocks. Took my time with this, got the fit just right then glued them on. That was yesterday, today I cut some string groves and went for a better brace hight. Not looking bad on the tiller tree at 20 in or so. I am happy with the mid bend, just want to thin down the outer limb to bring the tips round to more of a compass. No crystals so far but I reckon if I pull her any more she is going to pick up too much set. So its some more heat treating for this stave.

good work Nathan! impressive! makes me want to start a ash warbow right away... wich I maybe might :) Warbows are great to make aren't they?

you'll do good to remove some wood at the midlimb and outer limbs, but try not to remove anything after the tiller is perfect. You can always make lighter bows, but it's pretty hard to get them heavy.

you inspired me for another self-warbow dude!

Hello Nathan,

wondering how this one ended up!?

I had some very surprising results with ELBs  made from thin ringed heat treated European ash and I would want to give it a try for some 90-100# at around 31-32" pull. Would be nice to hear what your final result was!

Thanks.

PS: Are you still in Germany?

In my experience you really need to trap the back heavily, upto a 1/3 narrower than the belly. Ash only chrysals because it's way stronger in tension than it is in compression and most people don't bother to trap (*also if you are rounding the belly at all....). I've probably made more bows out of ash than any other wood because it grows nice and straight here and I can see the difference between non-trapped and trapped plainly when I compare very similar bows. I did a test with a little ash d-bow once,I made it short got the tiller good then pulled the heck out of it! Result = lots of set! About 3-4 inch. I then took that bow and cut it along the netural plane on my bandsaw. The belly half had more set when cut maybe 5 inch and the back had maybe an inch tops. So draw your own conclusions :) This bow wasn't trapped.
Ash can make excellent bows when treated correctly- contratory to popular belief! One of my best flight bows was made of ash.
