Estes DARC-1, #7307 Build Part 5, Interior Mount

The laser cuts left some browning on the edges of the centering ring. Most of this can be removed with a white eraser. 

Use a white eraser, a pink (pencil end) eraser can leave a pink color.

The shorter body tube (Part J) was a tight fit in the ring. The hold down tics were shaved down with a half round diamond file.

The launch lug fit was also tight. A sharpened dowel widened the hole a bit.

With the L spacer piece glued on there was a slight space between it and the launch lug.

FIX: A rectangle piece was cut from the leftover cardstock and glued to the top of the "L" spacer support to fill in. Keep the leftover cardstock pieces for quick fixes like this.

One of the shock cords is knotted and slipped through the slit in the centering ring.
