I can see how foam core gives a bowyer consistant performance and feel in shooting a bow over traditional cores but I do have reservations about HOW MUCH difference some claim. I rember way back when.When bamboo cores became the RAGE in traditional bows.I also remember you could get different results in performance from one set of limbs to another that where built to the same specs.This difference IMO is what foam cores help emliminate. I'm not a bowyer,but it seems to me.If one was to take the time and pre-test and select core materails that have good consistancies along w/ a very good limb design,you can acheive very good results. For me.I don't like the looks of that gray line in my limbs.If they would make in black.I would be just fine w/ it.

All true and especially true with actionwood or action boo .However there is one other thing. The foam core is impervious to cold and heat and to moisture where wood and boo are not. As to the color. Not a lot you can do about that unless you use a black sharpie.

Maybe Sixby but you can't build a decent bow limb out of foam alone.I also feel that the finish on and how well it's applied has more to do w/ making a bow weatherproof than putting foam in the core. .

I hate to disagree with this statement, but brutha, you are dead wrong on that one. there isn't a sealer made that will keep wood from being effected by humidity and temperature change. Wood moves a lot. Foam doesn't expand and contract at all.
bamboo is a great compromise because of it's homogenous nature. it also does much better in climate changes than many wood species does. i wish the stuff was better under compression so you could snuggle some belly carbon up to it without building a bomb. With glass it's not an issue.

I don't understand the point. finish may have something to do with weatherproofing for moisture but nothing to do with heat or cold. I still do the same high quality finish on my bows with foam that I do with wood cores.
I completely miss the meaning that you cannot build a bow with foam alone. I don't believe anyone said anything about building a bow with foam alone. At least I cannot find that so what do you mean?

I don't know the first thing about building a bow...but nevertheless, this has been an exceedingly interesting thread! I'm all for increased performance and smoothness of draw, but the weather resistance factor is especially interesting. Thanks guys! Joe D

This is another feather in the hat of Trad Gang, if you ask me. Being able to have a discussion about bows and having bowyers taking part. Just another check on a long list of why I stop by here every day.

To build any limb,one must laminate materails together.To say carbon/glass and epoxies aren't effect by tempatures seems incorrect.I understand foam as a insulater but not the other materails used to build a bow limb. Odviously the amount of movement in wood isn't enough that one couldn't build bow limbs w/ wood.I'm referring to not allowing water into the limb w/ a sealer.Yes not all sealers are the same.I've had bows from dry climates blow up and delam by stringing or just drawing them.Both bows the finish was very poorly done and there where seperation gaps in the limb lams.The liklyhood that foam cores would've made more of a difference than a better job at sealing the bow w/ a good finish,dosen't add up. As for the finish it's self.I've had bows that the finish peeled off when sprayed w/ bug spray.I have a bow that the finish isn't affected by bug spay at all? I feel there are other variables that contribute to the durability of a bow and foam cores dosen't resolves those durability and weatherproofing issuses.I do understand how it helps the issue. Kirk, Aren't bowyers using carbon and boo on the belly of limbs now?

I'm sorry you've had bows blow up on you. poorly built and or sealed bows will have a tendency to do that...and it stinks when it happens
Nobody said that a bow made with foam cores didn't need a good seal coat.
Nobody said foam cored bows were bomb proof.
I'm sorry..but you seem to have some sort of vendetta against foam cores and/or possibly the bowyers on this thread writing about them.
Have you had bad experiences with foam cores or one of the bowyers? I'm curious as I have an order with one of them and I'm considering a bow from the other in the future....possibly with foam cores.
Otherwise, I just don't really see your point in this post. It seems as if you're putting words into the bowyers' mouth just to have something to rant about.

Kirk, could you elaborate on this a bit. I'm curious to what happens here. Thanks.
