Justin, tell me about the black marks on the fin.

Justin, tell me about the black marks on the fin.

Helps me maintain a near knife edge bevel (especially on fins that were already beveled in a different fashion). Having said knife edge bevel also ensures I get that critical first fin on dead nuts straight.

Fin 2 of 4 tacked...

Does the knife edge allow you to line it up with the tube marks better? What's your beveling setup? (carbide table saw or sanding disk)

I heard these Mach 3 rockets like to fly at the Rocket Pasture!

Yes, good line up front and rear.

We hope to be back over Labor Day sir.

I like the solid rod ends you're using. I'm starting to integrate them into my builds. That fence on your router table, is it 90° and you let the bit do the work?

Correct sir.

 

[rfjustin]

All four tacked now.

Working on the drogue recovery side of things and motor retention.

 

[rfjustin]

All will make sense down the road...

 

[Speaknoevil]

Hmmm...

 

[jd2cylman]

That's a mighty small drogue bay...

So that's fillet 2 of 4 done, starting to map out the nose cone, switch band, etc. Need to place a Missile Works order as well...

Back to the PVC cap (cause I'm still not gettin' it)...

Back to the PVC cap (cause I'm still not gettin' it)...

It's a cheap and dirty epoxy dam. Once the plate was installed in the booster, I needed a way to ensure I would not compromise the 7/16" center hole with epoxy flow. Since plate is both drogue attachment point and motor retention in one, I needed to keep it clean on both sides.

Then you just knock it out of there orbit becomes part of the rocket after adhesive is in there but keeps it away from the center bolt?
