3/8" lifting eye?

When I use locktite, I typically use the green because I generally do want the part to come apart eventually. Otherwise I use CA or epoxy.

I’m a bigger fan of U-bolts than eye-nuts personally. As I said in an earlier post, my L3 project is using eye-nuts and I’m drilling and pinning them so they don’t un-thread.

I’m no ME Bruce – not event close. When it comes to mechanical things, I’m a seat of the pants kinda guy armed with a few rules of thumb. Electronics and software are a completely different thing and even that is becoming a thing of the past. IT is rotting my brain. I’m an EE with a CompSci minor who still kinda sorta remembers how to use a slide rule. I did learn Fortran using punch cards though back in 75.

I used Fortran IV back in 1970! Ever drop your cards? 🙄 I can get the blue apart, and I just use the red on joints I don’t want coming apart. Guys, I’m not aware of the green… ❓

No welded aluminum rockets, or in other words no rockets constructed primarily of metals at commercial launches. No reason to do that anyways, composites and other forms of construction are easily strong enough to meet the demands of a rocket, they also weigh a lot less.

Unless you are the BEE team….if you know what I mean!

Ha! That will never happen again, I mean BEE will never fly at our sites again as long as I am alive.

THUG SMASH!

Now we’re wandering pretty far afield from where this started which was John looking for a 3/8″ eye nut and then apparently on the flavors and colors of Locktite.

I was particularly found of the look on Joe Latrell when I told him I’d give him the GPS coords of the BEE bird out on the prairie in return for $50 for the gas and a $200 donation to NCR. They stopped by my house in Longmont on their way up to the site, wrote me a check and went to pick up their bird. Along the way they pissed off at least one rancher too. Actually, while those guys may have rubbed us the wrong way for a variety of reasons, I can’t fault their motivation. They’ve developed a bird quite different from the run of HPR technology on their own and from the ground up. So far, they’ve had more successful flights than failures. Hell, they gave James an excuse to build an O motor, you can’t complain about that.

Here is my two cents. Use what you are going to use. Every method has pros and cons. The strength of todays bolt material is sufficient enough for most of todays projects. I also have seen in both mount systems that have gotten ripped out say during powered accent and the chute comes out and subjects the rocket to some severe forces. I have seen eye bolts bend, rip and tear, I have seen them get ripped out of motor cases. I have seen lifting eye pull threads and let go. I have seen u-bolts get ripped out of…yes…G10 and plywood. Most people use all thread with lifting eyes, that is the weak spot on that design as all thread is rated less than a grade 1 strength. So stop arguing over which system is better. They both work the about the same. Use what works for you.

Me I would use lock nuts. Loctite is a great product but can be a pain to work with out in the field without the proper tools. Also tends to bunch up (goober I call it ) when removing it etc.
