a wet spring.
« on: May 10, 2007, 02:30:04 am »
wooden springs I mean.

Hello.
I was wondering how attentive you are to the moisture content of your warbow?

were you to find yourself floating around on a 15century warship such as the Mary Rose what could you realistically do about it?

If this has been explored before I'd like to read about it.

(Understand I am far from being an expert, dabbler might even be a stretch.)

It is hard to imagine aboard ship being a dry cozy environment. I would not be surprised to learn the relative humidity to be near 100%
i can't be convinced oil and wax type finishes can protect against  moisture exchange in a meaningful way.
what would (or could) you do as a bowyer to assure your bows will maintain a minimal level of martial effectiveness in such an environment even for relatively short periods of time, 1 week, 2, a month?

thank you for your consideration.

That is an interesting thought. I have wrestled with the question of protecting wood in respect to Viking longships and the equipment they carried on voyages, sometimes lasting years. The Norse used bows as well as wooden shields, iron implements, etc, and how exactly did they protect all that stuff? I was never in the navy, but know the deck guys are always painting, chipping, painting, chipping, etc. It is constant work to take care of a sea going vessel, and for warriors, weapons are always impecable and ready for instant use.

Not much is known about paints used in 1,000 years ago, and medieval times are not that far beyond the time of the Vikings. As for other kinds of wood finished, and for bows, too, does anyone have any reserach or ideas? 

I would guess though that the Englishmen's bows were not meant to be stowed in a ship for longer than the time it took to get the foot sloggers to where they needed to go. And wooden ships were always leaky creatures. That is what pumps are for, and the daily job of pumping the bilge for the deck hands.

Hi Dane,
The finish was not the point.

 If the engagments were of such a short duration that the moisture effect is negligable, my lack of understanding for exactly how such ships were used may well make the question moot.

However with a lack of sound moisture proofing isn't a possible solution to add more wood, resulting in a high draw weight dry bow, somewhat lower draw weight wet bow?

beeswax, beeswax and more beeswax. Ascham talks about weather proofing your bow and it all comes down to use a ton of wax, over and over again. That and wool bow bags.

following quote from Toxophilus; Roger Ascham 1545 (I think)

Phi. Well Toxophile, I see well you be cunninger in this gear than I: but put case that I have three or four such good bows, piked and dressed, as you now speak of, yet I do remember that many learned men do say, that it is easier to get a good thing, than to save and keep a good thing, wherfore if you can teach me as concerning that point, you have satisfied me plentifully as concerning a bow.

Tox. Truly it was the next thing that I would have come unto, for so the matter lay.

When you have brought your bow to such a point, as I spake of, than you must have an herden(?) or wollen cloth waxed, wherewith every day you must rub and chafe your bow, till it shine and glitter withal. Which thing shall cause it both to be clean, well favored, goodly of colour, and shall also bring as it were a crust, over it, that is to say, shall make it every where on the outside, so slippery and hard, that neither any wet or weather can enter to hurt it, nor yet any fret or pinch, be able to bite upon it: but that you shall do it great wrong before you break it. This must be done oftentimes but (e)specially when you come from shooting.

Beware also when you shoot, of your shaft heads, dagger, knives, or agglettes, lest they race your bow, a thing as I said before, both unseemely to look on, and also dangerous for frets. Take heed also of misty and dankish days, which shall hurt a bow, more than any rain. For then you must either always(s) rub it, or else leave shooting.

Your bowcase (this I did not promise to speak of, because it is without the nature of shooting, or else I should trouble me with other things infinite(ly) more: yet seeing it is a safeguard for the bow, something I will say of it your bowcase I say, if you ride forth, must neither be too wide for your bows, for so shall one clap upon another, and hurt them, nor yet so straight that scarce they can be thrust in, for that would lay them on side and wind them. A bowcase of leather is not the best, for that is ofttimes moist which hurteth the bows very much. Therfore I have seen good shooters which would have for every bow, a fere(?) case made of wollen cloth, and than you may put 3 or 4 of them so cased, into a leather case if you will. This wollen case shall both keep them in sunder, and also will keep a bow in his full strength, that it never give for any weather. At home these wood cases be very good for bows to stand in. But take heed that your bow stand not too near a stone wall, for that will make him moist and weak, nor yet to near any fire for that will make him short and brittle. And thus much as concerning the saving and keeping of our bow; now you shall hear what things ye must avoid, for fear of breaking your bow.

Hi Loyd.
That's pretty good.

I wonder what he means exactly by "crust" The finish he is describing sounds like nothing more than burnished wax. The solutions sound quite functional for average inclement weather. By average, I mean like me and you, able to return home to the fire.

I f you shoose to take every word literally and the description precise. "Always run it or else leave shooting" always?

Wax is cool stuff but it's not quite the ultimate finish described.

Actually is says "always rub it or else..." and you can never take Elizabethan writing literally

England is a wet place and I agree that wax alone cannot be the ultimate sealer even in the 16th century although they obviously had lots of experience in maintaining their bows and other woodwork. But if you did wax your bow every day before you went out shooting  it would pretty much water proof it temporarily at least. And if I was on campaign and my life depended on my bow you can bet my wax encrusted fingers that I'd be rubbing the damned thing down every chance i got, and the bow bag too! I've see wood work that's had a gazillion (give or take a few) layers of beeswax on it and it may as well have been varnished. All I ever put on my war arrows is linseed oil and wax and I've never had any problems with moisture. Granted arrows are not the same as bows but I think you get my point...

Ah yes, my typo sorry.
I like oil, wax finishes too. Wax is quite serviceable in a limited manner as waterproofing. Liquid though is not the problem. vapor will certainly pass through the treatments described.

I wonder if packing a bow in a container that was fairly well sealed and contained salt if the salt would collect the moisture in the case? Steve

That's a very good point. Someone would have to make a replica, store it in the same conditions and then test the draw weight.

I think this is one of the many reasons why they preferred Yew.  The moisture content of Yew doesn't make as much of a difference as it does in white woods like ash or elm.  Hickory can make superior flight bows at low moisture content, but it would not have been practical while campaigning in the pouring rain.

Hi Simon, JD.

That might be ok Simon, but what are the conditions? I know I'm not the man for the job. :)
That's a good point JD. I wish I had some experience with yew, but I'd rather rely on the wood than the coating.

My point has been that replicating the size of MR bows may not give an accurate picture of their performance without consideration of their operational environment. It could well be that a combination of diligent care and wise material selection, somewhat brief excursions negate the effects of damp environment.

or it may be that MRBs are somewhat oversize to compensate as well as possible for marine use. which is where I place my bet.

If a stave has high moisture content it will follow the string considerably.  The MRBs don't show much set and sometimes none or backset.  The bowyers supposedly air-dried their staves for 7 years so they had an understanding of the affect of moisture content.  It is most likely that bows were kept in human environments where they would stay suitably warm and dry.  A day marching in the rain won't hurt a greased-up bow at all and a night by the fire will have it as dry as ever.  Most primitive cultures seem to be savvy about moisture content, so I don't think there is any reason to believe that the MRBs had to be significantly overbuilt to allow them to be soaking wet.  Also, historical accounts tell us that the archers were very in-tuned to the affects of moisture (i.e. removing and protecting their strings at Crecy when it rained).

I often wondered whether submersion in water would straighten out a bow with string follow. But Apparently the Meare Heath bow has string follow despite being in a bog for a few thousand years.

JD, weren't most of the MR-bows unused? - so no wonder they didn't have stringfollow   ;)

Very interesting discussion by the way :)

Hi Simon,
if you were to soak  wood and dry it "straight" it would basically stay that way.

I'm less sure that the bow would keep its shape once sent back to work.
