Lookin' great Steve! I am jealous of just how much real estate you end up with on a sled in a rocket that size. I'm working on a 38mm av bay now and its tight as heck! LOL! Keep up the great work! :)

Fins are tacked on, I'll be injecting the fillets Wildman style.
Probably will not get to the fillets until after Christmas, my wife wants the table back.

I guess, I'll need a new scale, since the booster is already over 20 lbs which is the max weight of my scale.
Up to now I have always been able to weigh the individual pieces of the rocket.

Internal fillets are now injected.

I would move on to the external fillets, but Chris is out with friends and if I mix up a batch his rocket needs fillets done also.
We'll kill 2 birds with one stone tomorrow.

I have started working on the removable nose cone.
I don't think the strength of the PML nose cone compares to a filament wound one, so I have beefed up its construction.

I have 2 centering rings glued on a 98mm phenolic tube.
To that I'll attached the bulkhead with 5 1/4-20 screws.

I'll inject the nose cone with epoxy to hold the centering rings firmly in place.
Just need to get to Home Cheapo to get a toilet bowl wax ring to coat the screws with before injecting the epoxy.
I just like that wax better then Vaseline or candle wax for coating the screws for some reason.

Here are some pics.

Nose cone is completed, boy is there a lot of room in there.

8-32 screws for ebay are now epoxied in place, I'll make prettier once the epoxy starts to harden.

Ebay and nose cone put together.

The flush mounting of the 8-32 screws and the Schurter switches came out pretty good.

Thanks Coleman, it has been slow going up to this week, but the end is in sight.

Now the first set fillets are on.
That took almost 6 pumps of West system epoxy with colloidal silica for just 1 fin, usually one of my builds only takes 6 pumps of epoxy, not just 1 fillet. :lol:
Bigger fillets are definitely a lot harder to get perfect, looks like I'll be doing some filling on these fillets. We'll see after after they are sanded down.

Since I took the rest off the week off, I'm hoping to have it finished by the end of the weekend and ready for paint.

All the fillets are now done, even had left over to have Chris finish the fillets on his rocket.

Time to start thinking about what colors to paint it.
