Yeah, I would think that they would push the replacement closures out to their vendors for distribution based on the fact that THEY identified, based on PO, who got what and when.
It will be a while for me to get any, as I have no reason to order until propellant is being produced. Freight is too expensive.
Are you saying CTI will charge you shipping for replacement warranty items??? If so, seems a little strange...oint:
With the infrequency of orders in this hobby, you would think they'd realize they need to foot the bill on this and get the parts out.
I went through my inventory and found 4 suspect motors and started thinking. (Rarely a good thing.)
If you are using altimeters to deploy the separation charge anyway, why couldn't you fill the remaining space over the delay grain with J-B Weld. You wouldn't have tracking smoke but also no risk of a forward closure failure. Any reason this wouldn't work?
I've been thinking about that as well. It may work, but on the other hand the epoxy might not stick to it like it usually would since thats what's wrong with the parts. Then again, the only way to figure it out is to try. Perhaps you could static test one motor with the epoxy filled forward closure to see it it's safe?
Because the delay assembly plastic contains a silicone mold release and the epoxy will most likely not stick well to the plastic, and the delay grain will let hot chamber gas into the epoxy filled BP well, push it out and allow hot gases into the forward compartment of your rocket and cook it......I went through my inventory and found 4 suspect motors and started thinking.

That's why I use a penny at the bottom of the well.

Run a tap, drop the penny, epoxy in a threaded cap?
