checking splits in sapwood, is there a cure?

(1/3) > >>

RuddyDarter:
Hi,
Could anyone offer advice on some verticle sapwood splits ( checking)I have on a bow. I was told when I got the bow the splits were cosmetic and not deep and would not constitute a problem... and were secured with epoxy. It's a 130@32 and can draw to 33" alpine yew. They remained stable,  and I took it for granted and decided to shorten the bow a while back as I found it overly long for its size as it was 35mm widest at the handle and 80&1/4" in length (and i only draw to 31") ,which I have shortened to 77&3/4". I've had a fair few arrows out of it since with no problem but have noticed the split fixed with epoxy nearest the bottom nock has slightly started to migrate south and I can feel the edges of it. The outer limbs still need to be worked thinner as they don't bend enough at present but I feel that thinning the outer limbs anymore will compound this problem, it is lacking in caste without work done here.V It's a good piece of wood and has taken very little set surprisingly.
Could anyone suggest a solution to this problem?
Thanks for any help/advice.

I'm just finishing up a bow with exactly the same problem.  I think these are windshakes more than drying checks, but I've flooded them with superglue and clamped them up and they seem very stable now.  Unfortunately the customer didn't want the bow after seeing them, but somebody else might.  It's a nice punchy little 110lb so I might keep it for myself for Welsh class shoots :P



On yours, I'd be more worried about the one sitting on the edge of the sapwood than the longitudinal ones.  That's got potential to open up as it's going to be bending through it. 

You could always try wrapping with fastflight or something and soaking the whole shebang in superglue?

RuddyDarter:
Thanks WillS,
Yes you're right that side one is a problem, but not near the back but where it joins the heartwood, it was pulling away,
I ran in some superglue and it stabilised but I just felt that area and it is starting to feel a little raised again :-\,
Here's pic of area and another pic of where it is in relation to the bow (its the bottom limb),my thumb marking its location.
I suppose more glue and hope and pray, I should of followed suit like your customer, niave of me to accept it. :-\
Oh well...

Hi Mr Darter, that's a real shame about that bow.....are we allowed to ask who the bowyer was on this? Was a replacement or repair offered? Quite understand if you'd rather not divulge that info though.

Good viddy (I was fearing for your GoPro on the return leg though)!  :o

Hi John,
Ha-ha, the camera ( my only mobile phone pegged to the boss) services intact thankfully, I'm typing on it now...I was more fearfull than you John!  ;D
I feel any warranty or obligation would be now void after me shortening it. I'm  just looking for a solution to this potential problem.
 I think the best solution for me would be to go ahead and retiller the tips accordingly which would lessen stress at that side shake, and while braced (stand on string and draw it up) introduce some more slow drying epoxy into the shake on the back that's nearest the nock and unbrace and allow to dry. It's the lower limb so I can allow that tip to be a little stiffer. Seems like the best compromise to me(?).
I'm happy to stand corrected if an alternative remedy is suggested  :D
A little ticked off because of issues on all my bows recently, and a major sapwood splinter lift on my 140 :-\, but getting on with sorting them out. (Can a bloom of sapwood be successfully introduced to a bow of this kind of weight?)
