3" Brightstar is done and ready to fly. Won't be able to make it to a launch in January (getting knee surgery next week) - hope to fly it at MDRA in Feb.
These are Lumadyne "tube fasteners" that I got from Apogee. I think they are the only retailer left that sells them. The claim to fame for these PEMs is that they are coated with a material that makes the metal adhere to epoxy better.Really nice work, @mtnmanak. I believe I recall a PEM thread where you or someone mentioned that these inserts are not PEM, but another brand. Where did you find those? I really like the countersunk fitting for the outside of your body tube, but have never been able to find them.
Thanks for the pointer! I'd completely lost track of these after researching Lumadyne having seen the thread I mentioned. The price... well, there's the cool factor! I have an L3 build in progress at this time, and I was planning to use plastic rivets, but the cool factor is calling...These are Lumadyne "tube fasteners" that I got from Apogee.

I get you! I have two L3 projects under way (one official with my TAP and one that is a big ass rocket) and definitely planning on making copious use of the 6-32 size LumaDyne nuts.Thanks for the pointer!

I'm with you, brother! L3 attempts can be spendy.I get you! I have two L3 projects under way (one official with my TAP and one that is a big ass rocket) and definitely planning on making copious use of the 6-32 size LumaDyne nuts.
The cost of them is crazy for a small, cheaper rocket, but after I crossed 4 figures in cost on L3 parts, I realized the LumaDyne cost was the least of my worries.
