I think I will just stick to "using those big honkin' eyenuts"
Besides It was JW that turn me onto them a couple years ago.
It was his post with a link.

about just passing the Kevlar through the plug, tying it to a washer, and epoxying the whole thing in place. This would eliminate the eye bolt entirely. The only down side (assuming it would work), is that you'd have to cut a bit of Kevlar off each time to make a new connection -- you can't reuse the plugs. I think there's enough room in the plug to do it.

Anyone try this?

I use them all the time - but usually in bigger rockets where weight and/or space is less of an issue. I have a bucket full of them 🙂

Hey guys,

So i'm still curious, do we think the plug in the motor will hold 1/2" of 1/4-20 threaded rod?
Thanks

I have no expereince with this casing, but looking at the CTI website, you are going to have a minimum of 0.60 inches of thread in the end for you to screw into. Looking at one of the other cut-aways, you probably have more than that, but there are no dimensions to give reference to and I would not rely on scaling from the drawing. So I definitely would go with at least 6/10 ths of an inch. I am surprised no one has an answer for you.

Thanks for the input Bear. That's about what it looks like to me, but I figured I'd ask. I was surprised CTI didn't have the specs. on there site. I cut a few different sizes of all-thread to bring with me, but I'm going to pre-install the 1/2" one. Much easier to setup it up before I epoxy the bulkhead in place.
Thanks

What is on the other side of your all thread? I find for short lengths (<1" long) I trust inset hex set screws. You can tighten them down with an allen wrench and then screw what you want onto that.

Hey,

I cut 1/2" piece of 54mm coupler with a bulkhead on the on the aft side. Bulkhead will do 2 things, 1- hold anchor for lanyard to forward rocket section, with the all thread sticking out the aft side. 2- Piece of all-thread sits in front of motor 1" with 3/4" of the all thread showing for screwing the plugged motor into, so will be for motor retention. The tricky part I think is, i wont be able to use friction tape for extra security, because then I wouldn't be able to turn the motor onto the all-thread. I should have taken a picture before I epoxied it in. Hopefully the plugged portion of the motor can hold on, the caseing itself weighs just over a pound.

No I dont! Its composite. At least I would not trust it! There is a Blind nut you dont see in the picture above on the underside of that forward closure. The teeth or spikes have been flatened. The hole was reamed to accept the shaft or shank of the blind nut.
