And I'm finally back at it.  I can't believe it's actually been a month since I posted.  My bad.  I epoxied the second forward centering ring in place last night.  Again, I had to use my masking tape shims to center it since it was pretty loose on the motor tube.  This one was a little bit trickier since it will essentially "seal" the fin compartment.  Basically, the second forward ring and rear centering ring hold tight against the front and rear of the fin.  The placement of these is critical to hold the epoxy when I make the internal fillets.  It's not that hard to do, just requires a bit of forthought and care.  Everytime I mix up a new batch of west systems I get a little bit nervous.  I love the epoxy, but I'm always worried about something I might have fortgotten that will be impossible to fix once the epoxy cures.  I forgot to get a picture, but I'll fix that tonight.

On a side note, Northern Colorado Rocketry's Mile High Mayhem starts today.  Absolutely one of my favorite events of the year.  Whitney and I will head up early tomorrow morning for two days of launching.  Hopefully we'll get some good pictures to post here when we're back.  I plan to test some shock cord management methods on my 4" WHAMmer.  I'm hoping it will yeild some good results that can be applied to this rocket.
