The PainKiller 3 rocket thread

The unpacking parts count photo

First things first, giving all parts a bath, why? To get the mold release residue off for better glue adhesion and painting.

Parts list: one lower body section, slotted, one upper body section, one nose cone with aluminum tip, one ave bay/ coupler section, one nose cone shoulder tube. I think that's what it's called. One 54mm motor tube.

One decal sticker, two centering rings, four bulk plates for av bay two inner two outer, one bulk plate for nose cone and three fins.

The Aeropack motor retainer with the flange does fit the centering ring and inside the body tube. I don't have to buy a motor retainer, but not sure about the shock cord attachment yet. I have 60' of 1/8" Kevlar, not sure if I want to epoxy it to the motor mount or attach to the motor it self with a plugged threaded closure.

I'm going to be epoxying the cord straight to the MMT. I'm following the instructions for the 3" Darkstar thread that blackjack did.

Lookin good so far Sean.

Thanks Gary, I'm still prepping and getting things ready for the build, once I get more ca glue I can start the build.

Just about ready to start the build, just need more ca glue.

Sanded each bulk plate with 80 grit

Attached a inner and outer plate on a piece of 1/4" all thread so the plates are centered

Got the nose cone bulk plate CA in place with a 1/4" U bolt

Aft CR drilled, waiting to get taped

Using a thread tool to give the holes threads, since the CR is fiberglass there is no need for thread inserts

All the holes are threaded with bolts inserted


Got the retainer bolted on the Aft CR

Sanded the motor mount with 80 grit and drew a line on the side to aid In shock cord placement

Shock cord attached using CA glue


I use tape on the forward CR to keep the ring level while the CA sets then remove tape. I normally don't glue the Aft CR on, this time I did and later will drill holes next to the fins so I can inject internal fillets, there is not much room to do it with the aft CR off

Got some of the av bay done, still need to cut down the 1/4" all thread

I inserted the av bay in the aft end of the body to Mark my lines

I did the same with the forward end of the lower section and upper section of the body tube and marked each line with an SP and VH, SP: shear pin, VH: vent hole

Everything that has been glued using CA will get a generous dose of Aeropoxy ES6209 epoxy fillets.

Is 1/8" Kevlar strong enough?

No, no problems posting pics, are you having trouble seeing them?

I only see the link, the link works but no actual pic in the thread like your previous posts.

The fin slots are sanded and test fit the fins, love the fin design on this rocket

The marks by the fins are there to tell me which fin goes to what slot, the fins got marks on them as well

Not sure why, I'm posting from my I phone.

For some reason the pics are over sized, I've posted pics from my I phone before with no problems. I'll see if I can figure this out.

Gary can you see this pic when open?

Hey , Everyone is having trouble uploading.

Ok, let's try this pic.
I'm drilling and taping the upper body section and av bay, I'm using 6-32 screws

So it's the whole TRF web page and not just my thread?
That would explain a lot.

I have used this in another build, seems to work very well, it's fiberglass mesh used for drywall seems. After the epoxy cures I'll put another coat of epoxy on

Sean, here's some inspiration.

I have no idea why the photos are not coming up, and I can't figure it out, I'll keep taking photos of the build but not post them till I can figure this out.ill try reposting an earlier photo to see if it does the same thing.

Nope still not working. Would some one else have any ideas on how to fix this or what is causing this to happen?

I can see all of the photos just fine looking great!
