Good Job Cecil!! 

atsfguy:
  Is it necessary to isolate the coupler pockets on Blue Box engines? How would I do this?
Man, mrr is so different from fifty years ago, but in the best way possible. Wish RP had been available then.
  Thank you in advance for your help.
Cheers,
Cecil

I kept only one very old Blue Box engine, a PA1. I did not have to isolate the coupler pockets.

atsfguy:
Thanks, Al.
