Winter is coming, Though I've never worried too much before but lately I have been hearing stories that bows can break when used in below freezing tempertatures?? I've got some new bows I'd hate to break, so I was wondering if it was just a rumour, or can it happen??? Does anybody have that unfortunate experience?

Never had a problem with mine,of course it hardly ever gets lower that the low teens around here.
I always draw it a few time at short draw till I reach full draw first thing out.Sometimes it feels heavy but that could just be me and cold muscles. :)

Pappy, sounds like you never get frost over there???

I smashed a sinew backed bow on the tiller tree, it had been in the garage and there was a hard frost overnight. I think if I'd been patient and bought it indoors for an hour or two it probably would have survived.
I was just reaching for the camera for that nice full draw pic when KABOOM.

No problems here been out in around 0 deg F temperatures. I have friend who likes to make bows from yew and won't shoot a yew bow in the winter. He's had one or 2 explode in the cold. FYI- I let the bow acclimate to the cold for several minutes before stringing it up and shooting. Bowyering is done in a heated cellar. :) Jawge

Pappy is in the States and we use the Fahrenheit system here, "in the teens" is well below freezing (0* C = 32* F). I live in Florida, so the only frozen things I deal with come out of the freezer. I suspect bow breakage has to more do with the low humidity associated with freezing weather than the actual temperature. Our humidity level was at 97% last night, and I had to turn the air conditioning on again just to fall asleep, so take the advice from someone that has more experience with this than myself.

I think you mean pleasantly warm. No, wait they call it hotter than H... ;D I deal with the heat, my nerve response is just too painful to cold temperatures. I like it here, but it can get pretty brutal some summers.

I have mostly boo backed bows but have also had no problem shooting selfbows in temps below 0. Just went hunting in the snow the last few days with temps in the 20's and no problem. I suspect extreme cold does make them more brittle I just haven't had one break from it yet.
-
I have heard that yew is adversely affected by extreme cold but I've not heard of other woods being affected except to git a bit stiffer.

I live in Central Florida and we have frost and Temps dropping into the teen's. I had a bamboo backed osage blow up like a bomb on a cold, frosty, morning. I think the Temperature has more effect on the epoxy used. I know if you freeze epoxy it becomes very brittle. I seperated a takedown handle that got accidently glued together by freezing it with Nitrogen.

:D :D :D :D It's -30C here this morning, and I definately won't be shooting outside today! I won't be turning on the A/C tonight either :D :D

I have a nice tree of heaven flat bow that I shot all last year. Got pretty cold last winter, I took the bow out for a shoot in -14c and it felt a little stiff and developed a few small compresion fractures on the belly (i did give the bow a good rub to warm it up before I shot it). My guess is that wood behaves differently at various temperatures. My advice is go easy and keep a good eye on your bow. Better still use your least favourite bow, that way if it does adversely affect the wood you wont be too upset.

My mother was in Siberia for 2 years teaching English. It was -70 in the winter, and that was before the wind blew at 60 kph. Ill keep our lows with average in the high 20s.

RIP...yew longbow...same thing just happened the other day, to ayew longbow an old friend of mine bought from me and gave to his dad. His dad lives way up north where it gets damn cold. I guess some other person strung it and drew it and it broke, and now my buddy's dad is kicking himself for ever letting the guy touch it.

thanks for those replies, it appears the rumours are true, ice affects bows! I guess it affects near everything else!, so I better be cautious. This farenheit system is confusing also ???zero should be zero ???. I envy you guys who dont get the frost.The humidity here right now is 95%, but its cold aswell, about10"C,but I dont envy you Adb, where do you live?? Thats interesting about epoxy! Great forum, ask a question and you gets loads of practical info.

Dragomann! The RH goes up in cold as in your room whan not heat it to 22C just to 17-18. After 0 degreesC will fall down fast because the RH freeze out from air so it coud going down extreme low in extreme cold.
I dont think it has a recepie for shooting cold, some woods and bows may stand better than others. Take a look what kind of woods and technic the hunters use for making bows in north.
Use a bow in cold needs more care. Less drawlenght or brace it lower , brace it inside and not in cold. Than before use warm it up some short than longer slow draws before "full" draw it. If not shoot it for a while this method starts again.
Someone sad to me ash is ok in cold. I m not tried my selfbows yet but will. Winter use my glass laminated bow that shure safer to shoot. ::) ;)

:D :D I live in Saskatchewan. That's a province of Western Canada. Gets bloody cold here in the winter. It was -41C with the windchill a couple of days ago. Makes us tough, and the deer huge. The current world record typical whitetail (Hanson Buck) was shot about 1/2hr from where I live, in a little town called Biggar. Texas... pppft... Texas is big, but this is Biggar. ;D

Western Canada! Talk about dumbing it down!

adb, you're not kidding about the cold. My last trip to Northern Manitoba was cold. I stayed in FlinFlon on the border with Saskatchewan and drove NE every day 160 KLM. The last day it was -52C with the wind chill. I couldn't wait to get back to Florida. :)
-
-52!!! Wow, what were you doing up there?
-
I was hand drilling through a frozen lake that was contaminated by a copper mine, taking samples of the bottom sediments. I was finished before that late storm came through and waiting to go home.

wood is a moisture sponge.... the moisture content in all woods raise and lower constantly, unless it is in a stable inviorement. there is no sealer made that will stop those MC measurements from changing either...furniture, doors, old wood windows, and bows...
so if you have a bow that home is in the desert, or a very dry climate. that bows moisture content may stay at 7-8 percent all year. you take the same bow and hang it in my shop in oregon, and the MC will jump to 12%....if i bring the same bow in the house where we are running the wood stove, it dries it back out again.
the reason fridgid weather blows one bow up, and not the other has more to do with the mosture content in the wood freezing than anything else.when water freezes, it expands...the extremely cold weather effects composite materials in different ways too.... warm.... flexible.... cold... brittle and stiffer.
if i'm hunting in snow and cold weather, that bow of mine goes in the sleeping bag at night with me... :D
-
that makes sense about the moisture content. So i really do have to be carefull, because around here is very high humidity, it has nt been below 85% for a month now, if a bow from this part of the world freezes it is full of water and gonna likley snap!!
I do know about cold guys, the wife is from norway right inside the artic circle where the sun doesnt reach in the winter and like canada it gets pretty cold.
