Oh I see scale... Well the Nike-Ajax is sort of scale.
And the Redtop is based on a scale missile. But I thought you just wanted to know if anyone was building, or just talking.

John, Any chance of getting some dimensions for the lower Payload section ( and the adapter below it ) , even if the data consists of drawings generated by you, as opposed to original Aerojet data. Dave F. |

John great work!!!! Hey I have the Rocketarium Super Chief kit. I can not find much of any (one small blurry color photo) details on the net to help me detail it. For fun, not for competition. Any place you can point me with better scale details? Thank you! Nice work!

So, some action shots:
First picture shows my two concurrent projects right now: the BBR Javelin from the first post and a 2650. The Javelin assembly will be complete this weekend, I've added card stock wraps and will add more cardstock and thin cardboard detail after the fins are all glued on. This weekend, all fins will be airfoiled and attached at the same time the motor mount is added so all of the glue dries together. It's all lite-ply and paper so everything is put together with Titebond II. The 2650 was a long-term project to use some 29mm tubing that were crush damaged in transit. As you know, repairing bent tubes usually leaves them weakened. Having no other use for the bent portions, I straightened and patched the tubes as best I could using super glue and yellow glued them to each other with the repaired areas rotated out of sight. It came out strong; I am not the least bit worried about failure under load. The glued tubes and the upper tubing have been sitting around a while (years). What got the program working was I spoke with Jim Bassham at BBR Rocket about laser cutting some ply bulkheads as I just could not stuff glue soaked tissue to seal off the three tubes where they joined the parachute section. My OCD would not permit such untidiness no matter how authentic it was. In any event, Jim cut some rings for me, the catch was they were sized to match up with the outside of the tube. This was fine, but after fiddling with them, I decided to sand them so that they would be internal rings. The second picture shows the sanded ring. You may note that it is not round. The three tubes deform the BT-80 into a slightly triangular shape and with some careful sanding I was able to get a snug fit. I cut fins for this years ago. If I can find them, they'll go on this weekend. There remain some engineering problems like how to add an engine retainer and where does the Kevlar attach? But now that I have these rings on, I'm looking forward to finishing.
