its to strong for me . I can pull on 20 inch  :-\.  I have spoken with polish strongmen Mariusz Pudzianowski , we think about world Guinnes record , he said that he can pull bow over 250 lb. But make such selfbow ?? I think only great quality yew can take this. In Europe yew with over 30 rings per inch without knots is very rare. So This challenge can be hard to make. I think about hickory..

Might have something to do with that sharp cornered flat back, where it should be rounded to a circle at the tip...

Henry,
I don't care whether your bow runs supper smooth into the nock, 150Lbs with 1/2" of follow is pretty damn impressive in my book.  Well done!

Well,  I'm not so sure Marlon???  Perhaps not at present but with a little training why not?  He is one of the all time great strongmen.  Wether he could bit a barn door at 10 paces is another issue.  Mark Stretton was actually able to hit a straw boss at a reasonable distance with his 200Lber as he's a strong archer not a strongman.  At our last EWBS shoot Al and I were hitting a targets with a fully drawn 170Lb Italian yew warbow and I don't find it hard to believe he's 80Lbs stronger than me.

Yes, well done Henry. Getting a big bow out, like yours, with minimal string follow is brilliant.

My point was not about stylistic correctness, but that a sharp edge can concentrate stress in tension to the degree that a lift on the edge is more likely.
Not that this is not necessarily the case, but a distinct possibility.
Perhaps if Bowmanyeoman took a long india rubber eraser that was rectangular in section and bent it then looked at the edge distortion the penny might drop and he would be a little less quick off the mark in making assumptions about my meaning.
FWIW

i think Yeomanbowman knows what he is talking about as he is a "Master Bowyer" in the craft guild of traditional bowyers and fletchers!
BTW, that is an excellent bow, well done is all I can say, bows of that weight are very difficult to make so you should be applauded.

Rod,

I fully agree with you regarding rounding the corners and understand what you are saying. I'm also familiar with the source of your analogy about the rubber (page 59 of TBB3) .  However, the above posting was you're first responce to Henry's bow and I feel that your comments (whilst correct) were not balanced as all you did was point out the negative and not it's many positives.  As a Moderator being balanced is incumbent upon you, surely?  I said it before and I'll say it again 150Lbs and 1/2" of string follow is impressive and the proof of the pudding is in the eating.  Something must be right, yes? 
For what is worth I think it is you who has made an incorrect assumption that I do not understand the concentration of stress with a back of this shape.  For further clarification I do not make my bows this way either.  I have made a self yew longbow that held the FITA unlimited world record and this did not have a square edged back.  Another of my laminated longbows holds the current FITA world record in this class and this is not square cornered.  As Yewboy kindly points out I an also proudly a Guild bowyer.

Rod, if you make and post a 150+lbs yew selfbow with 1/2" of follow I'll promise to try and find good points :)
