Hello, I've recently gotten back into this hobby after starting when I as in Junior High back in the early 70's then taking a break, going to college, getting married and having kids. Got back into it in the mid 90's and then took another long break until just recently when I rediscovered my stash of rockets. Most were in pretty bad shape and I'm acquiring the parts to make repairs on a number of old favorites. However, I found one of particular interest. I found my old Space Shuttle 1284 that I bought when it first came out. I apparently got the SRB/Central Fuel Tank pretty much done and I remember getting to the Orbiter and stopping because I wasn't sure how to handle the vacuform parts. So I boxed it up and went to school. I don't know how it survived. After rediscovering it, I found that I had most of the parts except for a handful of pretty important pieces. Here is a list of the missing: 1) The ELEVON HORN 2) The PREPRINTED ELEVON HINGE SHEET 3) 2 OMS NOZZLES (they're the small rockets to either side of the orbiter's vertical stabilizer.) 4) 4 fin unit centering rings type CR-8 (they fit over the fin unit body tube ST-76) Okay, so I'm wondering if anyone on the forum has these parts? If so, could I get some measurments from you? I think some I could 3D print with some measurements. Here's what I need help with... 1) The measurments for the ELEVON HORN. In particular the Length, width and thickenss along with the measurement from the top of the horn for the hole that's used for the elastic string. And any other measurements you think needed. 2) The diameter of one of the OMS nozzles along with the length of the nozzle bell. Also, the diameter of the nozzle shoulder and it's length. Then the length of the pin area that attaches to nozzle shoulder to the engine shroud. 3) A scan of the Preprinted Elevon Hinge Sheet that I could print. 4) A part source for the CR-8 centerring rings. If there's a source for any of this information that I haven't found, maybe you could supply the link. Thanks in advance for the help!
