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.
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.
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... Apogee order underway.
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.
