Alright... Modification number ... whatever...

I have some issues with the forward bulkheads/thrust disk blowing out. My interim fix was so add a Semroc centering ring to the bulkhead and glue in place (actually the glue went in first).

That should give a little more grip for the bulkhead, plus there is some more glue up there.

My next section launch is March-14th, so we'll see how it works then - gives me just enough time to re-trim them...
