New Way Nike Ajax Build, Part 12. Interstage Support Details

The interstage supports are laser cut from thin cardstock.

TIP: Look close - you can see some rough edges. You can sand the edges smooth with careful passes with a sanding block.

Left is before, right is after sanding with 400 grit.

As shown in the instructions:

Glue the strip end first and let dry.

Notice the shape of the support piece. You want to glue the strip to the "flatter" side of the balsa piece. The bottom has a sharper angle.

I use very little glue to adhere the cardstock in place. Enlarge the lower picture to see the even fine line of glue centered down the outside edge of the balsa. This glue line shouldn't have much squeeze out, if any to clean up.

TIP: Run a small line of glue, then remove the excess by running your finger at about a 45 degree angle down the sides. this gets the remaining glue to the center of the fin.

These are glued down the three fin lines from the booster fin lines. as shown in Step 12 of the instructions.

TIP: The upper ring also has laser cut ridges. 

Sand smooth, then rub in a thin coat of wood glue into just the edge to seal it. After it dries, sand smooth with 400 grit.

I applied glue a second time and sanded.
