Detective Work On An Exploded Warbow

So is the term "Bricks" an official length or distance measuring system?

I can't find it in any of my cross reference books.

Sorry your bow blew up. At least the video shows me how you're pulling a 110 Lb bow to its breaking point without being some barrel chested tree trunk armed viking warrior. (Like those guys who used to come down from the north years ago and take all your countries good stuff when they got bored.)

Cheater.

I wonder if that small bit of something is equivalent to the puff of magic smoke that leaves an IC just as it dies.

Yeah, most jobs have that tell tale sign that make you feel sick to your stomach.
The darned thing would have been too heavy for me to draw anyway... Think I can just about draw the 100# these days.

"Aye" ~ ( They ALL do that, don't they...! )

(_{From an "Inspection" periodical}...)

I thought that the Mary Rose warbows were cut in one piece from heart and sapwood, one on the outside and one on the inside of the bow, the outside one working in torsion(?) and the inside one in compression.

I do not remember anyone saying that the two were glued together, I was under the (maybe wrong) impression that the whole bow was actually one piece/stave of wood. But two different woods/colours of wood.

I do remember that they said on the TV program that they were far heavier to pull than anyone had imagined today, eg. stronger....could put an arrow far further than previously thought....

You were making a bow from two pieces of wood....spliced at the grip.....I don't remember them saying that the MR bows were spliced.....but it was several months ago....

Surely having a knot in any bow is a serious unknown? and probably a weakness, as you may have proved.

This website appears to support my memories:-

I do understand that the failure was not at the splice, but surely, no matter how well you make the splice, it will usually be the weakest spot.

Thanks for sharing such an interesting problem with us all. Keep up the interesting posts...

Yes MR bows weren't spliced, I was just using up two short lengths of Yew. It's hard to find bits long enough. Splicing is a well proven technique and I've seen a 170 pound spliced warbow being shot.
Indeed the knot was a liability, but I had the two bits of wood so it was a chance to experiment and learn so that I don't blow up the 120 pound bow I will be making in november.
You are right, white sapwood on the back of the bow (away from the archer) darke heartwood on the belly (facing the archer).

the say a bow at full draw is 7/8 broken... well it's more like 9/10 or in this case 10/9

I do like your sense of humour and great knowledge. You are one interesting Guy!!!

Whatever happened to the Jap car of your Daughter?

The Hyundai went to the great junk yard in the sky, she has a handy little Suzuki Carry van now which she calls 'Binky'

Binky likes carrying stuff... it's his raison d'etre

Great news!

I wonder how she thought of the name????

I wonder what ran through your mind from the time you heard that distinctive "tic" till the bow exploded?

Are your bricks calibrated? Are they FPS bricks?

I actually thought.
"Is that, the back fracturing? No, it's probably just the string slipping a bit on the nock or the rope on the wich kicking as it settles between the coils. It's at about 100 pounds, I'll take it to 110 an then quit...&%$*! "
You can think quit a lot in that short ime.

The bricks aren't actually calibrated, but as they tend to stay still i can use them as a reference and measure them if necessary.
Maybe I should chalk a CE mark on the wall? That will prob stop the next bow exploding

You just need to use tic-less wood.
