Jesus & the Yew Tree
My disclaimer here is that I have no religious affiliation. I do however love history and stories. A couple years ago I purchased a book for Jamie's birthday and it is a most interesting read. "The God Tree" by Janis Fry & Allen Meredith.
It is a history of the yew tree and its connection to legends and actual events throughout our past. And definitely has a different perspective on some stories that we take for granted.
One of these is the story of when Jesus was killed and of his resurrection. Please note that this book has extensive references and you almost have to read the whole book as so much relates to one another. (For instance they spend a couple chapters explaining why the Tree of Life is a Yew tree, then this is the understanding for the rest of the book.)
From a Pacific Yew Tree to a Bow Stave
Harvesting the Yew
The last couple of weeks have been very busy in the shop dealing with a big pile of yew logs and getting them ready to dry and season safely.
There is a lot of discussion out there as how best to process logs into staves and I would like to take this opportunity to share my experience and findings.
I have found that the best and safest way to produce high quality staves for self bows is to start with green standing trees. The trees need to be felled and cut to length and ideally carried out of the bush gently to minimize damage to the bark and sapwood
Splitting Out a Stave
I have tried different ways of cutting up a whole log, but after all these years my preferred method is still good old fashioned splitting with a sledge and wedges, as follows.
That is how it is supposed to go, but often things don't go quite as planned and there are many things along the way that can affect the final product.
The first major issue we deal with when processing wood is twist. Pacific yew is very prone to twisting, it seems to just be a part of the species. Often you are able to see the twist in the tree while standing and they are wound up just like barber poles. Other times the twist is very gentle and you can just make it out in the bark pattern if you look closely. That would seem simple enough, but once you start splitting the logs up you can have ones that look twisted to split perfectly straight and you can have others that look straight to split spiraled. You never really do know until they are cracked open. We can still build bows out of twisted wood, but we need to spend more care and attention to untwist the bow during the build. I have found it best to try and limit the amount of twisted wood right from the get go.
The second major issue we commonly come across is drying checks. When wood dries it shrinks and as wood shrinks it can not shrink uniformly and so somewhere must crack and give to allow the shape to change. This is why we make sure to seal both ends of every stave we process. I have found that the flat surface of end grain is a very difficult surface for wood to maintain and it almost wants to check (fancy bowyers word for crack). I used to use wood glue to seal end grain, but now have switched to a wax based product. I have also found that any place on a stave where the bark has been knocked off is also sensitive to drying too quick and cracking, so I now seal any area of the sapwood where the bark is banged up
Another issue that we come across often is a ring separation. For some reason two years of the tree seem to have no adhesion between them and once split into staves they will separate no matter what we do. I don't know if it is from flood, drought, wind or what but this is a relatively common problem when working in yew staves.
This is not always a bad thing, depending on where the separation occurs we can sometimes get two "piggy back" staves. One backed with the outer sapwood and one all heartwood. I have made some really nice bows from these inner splits as the back of the bow is already down to one continuous growth ring. The problem is that we have no control over the thickness of the staves and sometimes they are too thin to produce heavy poundage bows.
Animal activities have proven to affect quite a number of the staves as well.
Lastly we need to talk about knots. Pacific yew is a knotty gnarly tree. The clean faces for staves seem to be the exception not the norm, and the percentage of trees which can actually yield useful staves is very low. It is quite common to have one side of the tree clean but the other side covered in large and small knots. We all know that bows can be made with knots in them, but we still try to keep the number of knots low. Even the nicest staves usually have a few pin knots here or there.
On to the Shop
After all that we are left with our collection of staves and now the bow making process really begins.
A few years ago I purchased a nice big bandsaw (Thanks Jenna!) and this really increased the number of staves I was able to produce. I still prefer to split my logs first to show the twist, but it now allows me to start slicing staves out of the big splits. Where as before it was too risky to split down any further, as I definitely didn't want to waste a good stave by getting greedy. I also prefer to saw the smaller logs as I found it risky to split logs smaller than 4 inches as the chance of the split running off the side was too great.
I hope this will shed some light on to some of what goes on before the staves arrive at the workshop, or at least help to appreciate the rarity and preciousness of a nice yew stave.
Yew Tree Chapel
This is pretty neat. The chapel is actually inside of the hollow trunk of the yew tree! It is the Saint Anne Chapel located in the cemetery at La Haye-de-Routot village in the Brotonne Regional Park.
I would love to offer gratitude and prayer, inside a yew tree...
