I had to go back and do a little more CWF fill where it fell out of the seam. This happens on occasion. I mark them as I find them using pencil.

After sanding the CWF to surface,

The tubes got a shot of filler/primer.

Notice the masking tape set inside the tube end to keep the interior surfaces clean.

On the right is the same tube after sanding. Filler/Primer fills what seam lines were left after the first CWF pass. Only this two-step fill is necessary.

The edges of the tubes got a wipe of CA glue using a Q-tip.

Use your fingers as a depth gauge keeping the CA line even.

The centering ring glue fillets are up inside the tube, not near the CA'd edge. Wood glue or epoxy won't soak into the tube if the CA glue has sealed it off.

The tube ends are sanded after the CA glue dries. 

This gives you a hard, stronger edge tube.
