I have the same problem on a '68 I've been messing with.  I showed it to Joe (Prairie Traditions) while at Compton, and he told me to "gently" clean it out using a razor and shoot some 420 in it.  

It's not real visible, but you can see some sanding dust in the crack if you look just above the bottom light colored lam.

Mine is small enough, and only on one side, so that a clamp wouldn't help any. I've twisted and pulled it and it doesn't open any more than this.  I actually didn't realize it was there until I took off most of the finish.

Off the cuff, without seeing it, I would say yes. I have fixed SK's with the same issues. Post some pictures and see what others have to say here.

I have a 69´ SK, same problem, i asked on this forum and they gave me alot of help, pretty much all concurred to clean it out if possible and fill it with Loctite, I did as best I could and injected with a hypodermic needle till it overflowed, then lightly sanded, seemed to work fine, i would post pics but have a hard time getting them on here! Many thanks again to all the great folks on here!

That is the only option that I am aware of for dealing with those cracks.  Some of the 67-69's have them, although most I have seen do not have the problem.

My thought is that filling with Loctite is helping to seal it up and prevent moisture from gaining access, which of course could lead to further problems.  But since you are not able to get any pressure to clamp the laminations back together I'm really not sure how much holding power the Loctite is adding to the joint.  

Does anyone have experience with the long term results of this type of repair?  I'm sure that the size of the seperation initially plays a big part in how well it holds up in the long run. I have one that just came into the shop that is wider than the one on Carlo's bow.  I really question this one.

There are actually seperations on each side of the lower riser, but they are not on the same lamination, so don't go all the way through.  On the first one, you can see where the core lamination has already cracked.  This one looks like a real problem.

On the opposite side, the seperation isn't quite as deep.

blow it as clean as you can with some light air presure maybe 6-8 pounds and then start dropping in the loctite.Is some cases the clamp will help but you should not use more then 1-2# of clamp pressure.Some cases the gap will not clamp tight.On those bows I just keep filling the gap until flush.I've made that repair many times and have never had any problems with the gap after filling with LT bd

Thanks for all the info. I can't seem to figure out how to post pics.

I guess this is still topic related, but I have some Loctite 420 on the way.  After I use the small amount I'll need, should I stick the remainder in the refrigerator or will it not harden up in it's container?

And spiritlead if you'll email me those pictures I'll put them up for you.

Refrigerate after opening - should last a good long while Carlos.

It looks to me like your bow is split in two different locations.  The top picture shows it almost down the middle, and then the others show a limb gap.  

Looks a little more serious than what I'm dealing with on mine spirit lead....

blow clean with compressed dry air Fill-er up I'd try to use at least one C clamp on those with very little pressure 1-2 lbs only.I like to glue a small peace of leather or thin wood to the C clamp jaws...Helps prevent more damage from the clamp bd
