Dr. Zooch Saturn V Build Step 11 Fit and Gluing Details Part 1

The S-IVB APM and S-IVB Ullage motors glued on.

Simply center them above the black /white color separation lines on the adapter wrap.

When set over the wrap, the S-II LOX Tunnel front ends are raised.

I filed a shallow step into the lower half for a better fit against the body tube.

This shows the better fit after notching the lower half of the tunnel.
