The fins are on Page 6, the body shroud is on Page 7.
Pages 6 and 7 are printed on 110 lb. card stock.
On the first print of the shroud I tried the "fit to page" setting.
It was a a little large with a ST-7 tube slid in.
A second print was made with the "fit to page" setting off. That seems to be correct.
My print was offset to the left and didn't get all the border lines. A little bit was cut off. That's okay, I can live with that.
A X-24 search on YORF brought up many different shroud skins, some you can make up in your choice of colors: CLICK HERE

The fins were printed with the "fit to paper" setting turned off.
You'll also need a sized bulkhead, called a "former" in the instructions.
For the former bulkhead cutting template, print off page 8 on 20 lb. paper.
In addition to the printed parts on 110 lb. card stock, here's the parts you'll need -
(not shown)
- The Estes plastic nose cone # 070323, the same small conical cone from the Yankee kit.
- 3" of ST-7 tubing (or BT-20 tubing, the slightly larger diameter ST-7 tubing will better fit the hole at the top of the shroud print. To fit the larger opening you can build up the tube top diameter with a strip of cardstock )
- 4 launch lugs, each cut to 1 3/4" long
- Cardboard for the "former" bulkhead. The original Centuri former looks like it was cut from light Masonite.
The original bulkhead was exactly the same as the bulkhead from the Vulcan, and yeah, I do remember it being Masonite. I had one of each back in the day; still have the Vulcan, but the oils leached out of the nose cone clay and ruined the upper part.
ReplyDeleteHi Chris,
DeleteI seem to remember my X-24 Centuri kit had the Masonite bulkhead former.
I've seen a few pictures of other old Vulcans and the clay had stained the upper part of the cone. There is clay stuck to the inside of the X-25 shroud but I tried to seal the cardstock with some glue smeared over the area.
I made a Vulcan clone a few years back. Before reaching apogee the rocket wiggles a bit.
