Thanks for the info , and links .

however..... the original Camroc ( and hence carrier ) transition out to a BT60 dia.

the Astrocam is BT55 ( actually ST13 ) dia.

I don' t think it would be too hard to modify the shroud to go to 1.325" instead of 1.637" - especially with one of the shroud generator programs ( need to download one of those myself ) .

problem then - is the base of the Astrocam, which is BT55 ( mine is now, due to sanding it down ) - so I would need a BT55 section at top of the booster ( inside the shroud ) to fit the camera shoulder into ..... ideas ?

will ticker with it some, but I still was certain someone had done this and published a plan, so trying to (1) not reinvent the wheel, and (2) be able to say I have one more 'plan built' , instead of just scratchbuilding, lol.

no rush, just thought someone here might remember the article,.. will try over on the old rocket list as well, see if I can rattle some cobwebs...
