H Bow

I was tidying the garage/workshop when I came across a skinny strip ofYew cut off the corner of a big quarter stave of Austrian Yew. I thought I might make a quick miniature...but why not two fixed side by side like a letter H ?
Long story short, I did it, the big decision was to heat bend the limbs so that they met at the tips with about 1" gap at the centre. The advantage being that it allows a single string.
I contrived a cunning extended grip arrangement so that I could draw the 17" draw ( the bow is 34.5" ntn) and still anchor at my normal place. This might be quite a punchy little flight bow, I was aiming for about 40# at 17".
Some tentative shots were promising and I posted some video on my Youtube channel (Del Cat)... I'd been posting the progress all along.
What would it do through the chrono... ?
First short draw shot 140fps.
Fuller draw 160fps...
Third shot... BANG

It exploded, one of the lower limbs blowing out between two small knots... really need clean wood for a flight bow.
I did a video autopsy too.
