Default Saturn SA-6 or 7

Well, I'm in the mood to build a 1/100 Scale Saturn 1b. Not really a 1b but a Saturn SA-6 or 7.
I know there are no differents in the SA-6 or 7 except the paint scheme. I like the black paint scheme best. Right now all tubes can be had at eRockets. It looks like the only tube I need to figure out is the Second stage tube. At this point, I'm not sure what tube to use I need some help on this. Just off the top of my head a BT-70. Anyone, please give me some feedback on this. The fins well have to be worked out also.


It's nice to be able to get the Apollo capsule from ESTES. If I get the tube problem figured out I will make wraps to do the second stage and change the tank wraps a little for this build. I really don't want to do all the extra pipework down the tanks but that's a long way off. I'm just in the planning stage now so any help or feedback is welcome.

Not sure if this will help any but the sizes for the tubes used on the Estes 1/100 Saturn 1B are below.


The short tube that the fins connect too. BT-83B 1.39" Long 2.698 OD , 2.656 ID

The 8 small tubes around first stage. BT-18A 7.88" Long .708" OD, .682" ID

The large Upper stage tube. BT--82A 7.635" Long 2.618" OD, 2.592 ID

Thanks, John, I'll take all the help I can get. I'm Keeping my fingers cross that ESTES rereleases the 1/100 Saturn 1b. To me, the 1b was the hot rod of the Saturn rockets.

Been looking around at body tubes and I have come up with an LT- 225 tube. The OD is 2.340 and that's the closest I can get between BT-70 and BT 80.

It is very easy to make a larger diameter tube from a smaller one, or a smaller tube from a larger one. Take a look at this thread starting with post #16.

Thanks, tbzep, I just may try that. The height of the tube isn't that much. Rocket of the World gives the measurement of the real SA-6 as 222.0 across so would a tube 2.220 be right? I'm new to this stuff. all help welcome.
