Looking for information on warbow dimensions and draw weight

My guess is that there simply haven't been enough replicas made to give you enough data points. Again I am only saying disappointing things. I apologize.

There may have been enough made, but they won't have all been measured at the required intervals!  ;D

All I really need to get started is the width and thickness at the center, length, and draw weight @ 30" for bows made from European yew. I'd be surprised if there weren't five of those based on a Mary Rose cross section out there. If that looks promising I can always go crazy and estimate draw weight based on the average of dimensions from every 10cm of the bow.

I was always dubious about getting the same information for shorter bows at 28", though.

meanewood:
The dimensions of the 'Mary Rose' bows vary as does the ring count.

Lots of those bows were recovered in storage boxes which may mean they were part of the ships store rather than personal weapons.

Common sense tells you that the draw weight of these bows would be closer than what the dimensions would suggest.

That backs up what most bowyers would say due to their experience with all woods.

Just thought I'd stick this in, as it somewhat applies here.

This is from Roy King himself, as he documented his original Mary Rose approximation bows.

"Sapwood worked down slightly to remove small bumps.  A good stave; no need to follow bumps...

Sides worked down dead square to back, to what should be finished width, leaving just a little extra width at tips... slightly convex taper...

Back generously radiused over full width, dropping a little extra at edges.  Then there appears as if by magic the Mary Rose sharp edge...

Coming to the conclusion that these bows were made almost by numbers.  That given the quality of the wood... a formula for manufacture could be closely followed... a system that isn't used in Victorian bows..."
