I wasn't sure if I should post this item here or in the "Projects" sub-forum, but ended up settling on this sub-forum, as the topic is scale in nature.

I've been reworking (which, in this case, is a way of saying "replacing") portions of my Argo D-4 Javelin, and the enclosed article shares a play-by-play of the updates I've made to the Payload Adapter. It's been a fun project for me, and I thought you scratch builders out there might find aspects of the build of interest.

I did consider a build thread, but given the length of the discussion, felt the article format was the better vehicle for communication. Apologies for the length, but hope the photos are of interest.

Looking forward to the rest of the build, with more close-up detail like this!

Some further progress on the Javelin 2.0. This time the subject is the Nike-Nike adapter.

With this adapter out of the way, I can turn my attention to the Nike boosters, and that Payload section I've been avoiding. Hope you find the article of interest.

That was a great read, great work, can you say how much the machined master part cost?

Several years ago, a program called "Yet Another Transition Template Maker" was circulating on the internet.

I saved it for "posterity" . . . ( ZIP file below )
