Hi, I'm Luke. I have been a rocket addict for one year now, no prospect of recovery :headbang:.
This build is a prototype thats already finished but is being updated to the newer design at the moment, has already flown a couple of times but will put it up at next weekends TRAAU launch if the weather gods come to the party. it takes 29mm and 38mm motors from G-J and fits a 38mm 6G motor but only just.
So first up i turned a mandrel out of wood that was 4.5" in diameter at the widest point, then gave the mandrel a few coats of epoxy and then sanded it smooth on the lathe again. this photo shows the mandrel before it was epoxied.
Next I made a straight section with an ID of 4.5" that i rolled on some mylar wrapped 4.5" pvc with an internal wooden cylinder glued inside to allow it to be turned on the lathe. this is what i do with alot of round components to get a great finish on the finished product.. this rocket was a prototype so its not gel coated like the others have been. I made all the parts with 5 layers of 287gsm (sorry for the metric and imperial... i'm from Australia so I'm aloud to use both ) and west systems 105 with 206 hardener. then once cured were sanded on the lathe until uniform and given another coat of epoxy with which is also sanded smooth on the lathe.
This is the Mini Nuke with most of the parts just put together to show what it will sort of look like followed by all the parts laid out for a few of the different coloured mini nukes.
the fins test fitted to the airframe, and then the fins when they were being tacked to the 6" fin band, then they were filleted and finally installed into the base of the airframe and onto the mmt, you can see an off cut of 38mm MMT that is just tacked with CA to support the fins while the fillets dry.
And here is the MMT and the rocket fully assembled to test fit the parts.
a42" Nuke Chute for made from ripstop nylon with 150lb braided kevlar shroud lines. also has a 1000lb braided kevlar shock cord and Y harness.
this is it with all assembled with a couple of coats of a high build spray putty (like a body filler but in a pressure pack, also drys very fast.), and some paint.
