ROI MODUS AND BODY MEASUREMENTS FOR MAKING MEDIEVAL LONGBOW
OTDEAN:
This post:
" I am 5’8” tall and this recipe gave me a bow of 5’11” and arrows of 31-1/2”. "
Has nothing to do with me personally, that is copied and pasted from the book that discusses the ROI Modus, not me. Those are the authors measurements from the book "with bended bow". My own measurements for 74" and 34" arrow are correct for me.
Those are the measurements for the author using the same technique I got 74" bow and 34" arrow, I personally am 6ft 4!

As Dean suggested above I just don't hold with this some/most ash is junk thing.
It's about getting the correct thickness for a start and then trapping the back HEAVILY and of course heat treating the belly.
Ash is massively strong in tension.
Compression resistance is somewhere about average.
Once you even up it's properties you will start to get great performance.
However I will say that ash isn't the best candidate for heavy narrow bows, especially when people insist on rounding the belly! Yew likes a rounded belly but ash, elm etc just don't.
74 inch will work for a 34 inch draw.
Width can of course be adjusted? Length isn't the only determining factor. The aim is to get the strain correct at full draw wether that be by giving it enough length OR width.
OTDEAN:
Folks really need to leave the poor yew trees alone and go cut some other bow woods and experiment. You will only learn that way. Banging on about junk wood is just a sign that you only use one type of wood or you lack the experience and knowledge to make a good bow from any wood.
WillS:
As far as I can tell, nobody is "banging on" saying other woods are junk, just that some wood is not suitable for a certain style. This is the warbow section remember.
Some ash is crap. Some is superb. The crap stuff makes good kid bows or light bows, but not heavy warbows. You can save it to a degree by heat treating, but it shouldn't be necessary. The good stuff makes very good warbows with no heat treating or trapping or anything else. The fact that guys like Jaro can make 160# ash bows with a ROUND belly and no heat treating just proves that fact.

Just for the record I stated my opinion that UK Ash is "poor" note I also asked if anyone had an opinion on the sapling vs mature theory.
I did not say it was "Junk"
On a scale of 1-10
I'd have thought junk was 1, but poor was maybe 3 or 4 :laugh:
Feel free to take my advice or leave it, that is the spirit it is given in.
