The PainKiller 3 rocket thread

I may go with CTI's New K520WH 54mm 4G or their J355RL.

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.

Just more clicking involved,, no biggee, pic's look great.

I gotta check out these motors. Gary, should I epoxy the nose tip on or just leave it as is?

Gary, should I epoxy the nose tip on or just leave it as is?

Totally up to you but what I do is:

Remove the Tip.
Take the washer and drill 4 holes at 12,3,6 & 9 O'clock
Re assemble the tip on the NC
Wrap a piece of electrical tape around the outside seam
Pour some epoxy into the NC, you may have to tip it side to side so air can escape and the epoxy flows through the holes

This will keep your tip centered no matter what.

Well it looks like things are working again with TRF. Not much building today on the rocket, I'm finishing the epoxy fillets on all the parts that were CA glued on. I'll start on the av bay sled and how I'm going to mount the electronics.

Thanks for the advice.

Why do you wait so long in between drilling the holes?

Why do you wait so long in between drilling the holes?

Just want to make sure I drill in the right spots. Like in my other builds I change my mind constantly when building a rocket. There is no reasoning behind it, it's just the way I do things when building a rocket.

I was teasing Gary about the 12,3,6,and 9

 

[Blastcap Rocketry]

LOLOLOLOL!! I didnt catch that either.. now THAT! was funny.

Doh

Put grease in the holes so the epoxy won't clog them up

Putting epoxy inside of tube for the motor mount

Top of the forward CR with epoxy fillet

Put the fins and retainer on to keep the motor mount in place while the epoxy sets

 

[Kehoes23]

Got all the parts for the sled cut.

 

[Kehoes23]

This did not work. Had to do a redesign


This design works, not done yet still need to mount the altimeter

The fins are sanded and ready to be tack on

Drilled 1/8 holes by each slot to inject internal fillets

 

[Kehoes23]

Got the first fin tack on

 

[Kehoes23]

Got all the fins tacked on, need to get a syringe to inject epoxy for internal fillets

 

[Kehoes23]

That's one nice looking rocket

 

[Kehoes23]

Inside the MMT, you can see where the fins and shock cord are attached

 

[Kehoes23]

So the 1/8 hole was a bit small and had to drill 11/32 holes to fit the syringe. Doing the forward CR fillet.

11/32!!!! Holy schnikees! How big a syringe did you get? One o them 50cc jobs we used to use on the cattle?

Yes I know the holes are big, I went to 10 different stores and this is the smallest syringe that I could find, but the holes can be filled in with epoxy, this is the reason why I drilled the holes next to the fins.

Injecting the first internal fillet

This is why I like fiberglass rockets you can see the fillet.
One internal fillet done 5 more to go.

 

[Kehoes23]

This is the epoxy that I'm using for this build, there are others you can use but I like using Aeropoxy.

 

[Kehoes23]

The last few days I've been doing internal fillets, nothing too exciting. Got two more sets to do. I've been racking my brain on what colors to paint this rocket, any suggestions are welcome. I've been thinking dark blue and light blue.

 

[conman13]

Metallic blue would be cool.

What! your not going to make it like the model??? LOL JK.. Paint it whatever color you like. I also have an all Black Profusion one with fluorescent Yellow vinyl, pretty cool.

PS, Anyone wanting a PK3? I'll be at URRF II with a few on hand, come say hello.

Since you put up a sales pitch on this thread, do I get a percentage of the sales? Lol
Every one, these are very nice kits, I recommend you pick one up and use it for your L1 and L2 certs, and if you have your L1 and L2 certs, pick one up anyway and use it for your workhorse.

I could never get this paint to look good. This color would look good, if I ever get it to come out right.

 

[Alethins]

I'm painting mine to look like a pain pill if I can get the design right...

 

[Kehoes23]

I should have had all the internal fillets done a few days ago but as we all know life sometimes gets in the way of building rockets, I still have one set left to do. I did get some small U bolts to attach to the av bay bulk plates, once I start on that I'll post some pics.
I have decided on paint colors, for the main body tube it will be navy blue, and for the fins and nose cone will be a deep blue but that's far a way and I might change my mind from now till then.
