Hello Asier! How are you! This is 120# at 32创 in ash.




Not as good, but not much follow, no frets either.

And this one is sort of 85# at 33创





I like that one best out of three.

Akila : its something like 34X27 mm at middle tapering to 18 mm tips (original taper) and then there is secondray taper something like 18 cm from each tip down to 11 mm nocks.  The ash has SG around 0.85. Hope it helps.

Hrotgar : when I lay this out I start making bow perfectly symetrical and with alot of more wood then needed. That assures that I have to actually struggle to get the weight down, rather than ending underweight. As I tiler I observe properties of limbs and chose the one with weaker wood as upper. Then I position bowyers mark and arrowpass 1创 up from geometricall middle of the lenght of the bow and adjust for slightly positive tiler at the end.

I have made 120# bow from the same wood, though with tiler not so nice.

Hey Jaro!!! >:D >:D >:D >:D 8)... ;) :D....

Thanks so much for repiyling mate!!!...REALLY glad to ear from you.

These two last bows you posted are EXCELLENT!!..NO DOUBT!!... ;) :)...

Why do you like that last one best than the other two?..the tiller of this last bow looks like shoots better for flyght shooting because of  it磗 slightly eliptical tiller shape I guess!!...Isn磘 it Jaro?... 8) 8)..

Anyways I like all these ones!!... :)..

Cheers fellow and keep us updated.

Akila the dimensions provided are at the handle - which means roughly middle of the bow.All those bows are oval, slightly more rounded on belly than back and somehow more flattish than if made out of yew.

Yes Asier, its because its omehow eliptical and it has best tips. Also very light in mass, though made from dense wood. It hasl best cast per pound from all three.

This is rather small yew bow of 60# at 31创 also somehow eliptic. Made from coarse wood. Does it looks thick! This is only 72创 NTN.



Enjoy!

Přiv韙at zp醫ky Jaro!  ;D

I remember these bows, very nice work mate!
I wanted to know, did you heat treat these bows? did not notice any markings on the belly so I assume you didn't, ja?

About the yew bow, very nice work!!!
Is this Czech yew? Looks to be mostly sapwood or is color just light?

Ok, this is not much related, but what inside diameter do you prefer on warbow horn nocks?

Again, as Asier said, its very nice to have you back mate! I hope to see you around more.  :)

Thks a lot...i just wanted to be sure....becose i have read a fiew topics aboute this bending thru the handle D bow, and there is a lot of people who are saying that the thickness of o bow like this should be equal to the width of the bow....this means that iff a bow is 34mm wide, he should also be 34mm thickk :-\...so this is why i asked you again if its in the handle or the mid limb....aniway thks a lot this realy helps me....i have an ash stave, and i did a test on it....i  put a small piece of wood in the watter...and she is all most coverd in watter.....just 2or 3mm of wood its not under watter....you think its a good wood????...the only problem is that the stave has a little propelor twist....its not verry sever...but its not straight either....you think this should be a problem, if i want to make a 120# bow???thks a lot again... and what can i say...your bows lok gr8....i  can only hope that i can make a bow like this from ash....aniway i will give it a try..

Alex, the ash bows are all heat treated, but only the 85# got really deep scorch. The yew is rather coarse, I took the sapwood down to two rings, suppose its the picture. Its also somehow flattish. (Oval)  Its what I do with any materiall which is less than perfect - I just flatten the same profile.

Akila - if you make a bow with the same width as thickness, you will have very unstable profile, unless its completelly round and that is far less the ideal solution. MR bows are between 1.1 and 1.2  (width/depth) ratio in the middle, but thanks to low width taper they are more flatter midlimb. Given the leeway BLBS gives, you can go as much as 1.6 ratio and that is quite forgiving to make.

Cut small block of your ash. Put in the water slowly. Take out. Measure the submerged part and the dry part. From that you can calculate SG. For example a a piece of SG 0.9  will have 9/10 of the block submerged.

A little question about how to tiller a heavy Ash warbow Jaro...of around 100# at 32.

What do you recomend me to do , as slightly elipticall or full compass tillered bow??...

I know that elipticall tiller is bettes for flight or target shooting due to the  lesser hands-shock the bow has, and in the other hand the fully compass tillered bow sould be better to launch heavy arrows, but..... what the heck...

What is nicer to shoot in your experience Jaro???

Thanks in advance!!

Well, with ash, slightly eliptical is better for cast and handshock elimination. I think. Its spongier in feel than yew or other harder woods.

Akila  3cm out of water if your sample is 5 cm means only SG of about 0.4. Can you just calculate percentage ? Its 5 grader stuff.
The width and lenght of the sample does not matter. What matters is how much of it sinks into water and how much stays dry.

I would make the tips between 11 and 12 mm in diameter where the horn meets the wood, when making 120# and having dense ash.
