I have the cambium left on a hackberry bow im working on. Recently a splinter lifted on this cambium layer and I had to sand down to the first growth ring below to get it out. I dont want this to happen again and have cambium splinters travel down into the first growth ring so i'm thinking of removing it or scraping it to make it thinner and do less work. The cambium layer is like a thin growth ring on this bow and I'm wondering if scraping it thinner will affect the bow's performance or if it doesn't add anything to the bow's performance? Thanks!

Cambium is much softer than the wood itself in my experience, and nothing I have ever read indicates it has any structural benefits. It is used for camo and I think it might be quite water proof. If the splinter you raised was in the cambium instead of the sapwood it is no problem, especially if you take the cambium off.

Actually, what I think a lot of people call the cambium is the inner bark, the zilum I believe. The cambium is a very thin live layer that is between the bark and wood.

Depends on how thick it is. Draw weight yes. Performance I doubt.
-
Cambium is likely not what you are seeing. It's about like a layer of stem cells like an onion skin.
-
What im looking at is definitely not a hardwood growth ring. If its not cambium then it must be some part of the inner bark. Its thick enough that i think it might effect the draw weight so i might just sand it smooth.

Figure out how to get all the bark off down to the ring and the problem will be solved.

Short answer:- No
Long answer:- Noooooooooooooooooooo

I want it all or mostly gone, it does no good and can cause problems when seasoned.

I didn’t know that. I have staves in the works I was planning on leaving the cambium camo on. Sounds like it would be better removed. What problems can it cause?

From what I've read it's weaker than the growth rings below it so it can suffer a tension failure and splinter and then those splinters can travel into the first hardwood growth ring below.

That's inner bark, as mentioned. For all intents and purposes the cambium is not visible.

Yes I meant inner bark not cambium. I think those two are easily confused. I've seen lots of whitewood bows with a "camo effect" that is referred to as cambium but in reality is just the inner bark still attached i believe.
