Build Thread - Wildman Jr. Two-Stage

@Antares JS --

I love your Silver and Gold paint theme !

I suppose the same warning about multiple coats does not apply to the gold paint ?

Sorry if I missed it, what brand is the gold paint ?

p.s. thanks for the Lab Rat Rocketry Pull-Pin tip !

Both the silver and gold are Rustoleum "Bright Coat Metallic Finish." The warning about multiple coats does not seem to apply to the gold. Someone who knows more about paint would have to tell you why that is.

Might have something to do with how the solids float on the solvents and binder when layed down wet, and that the solvents from a second coat may reactivate the lower layer and cause solvent evaporation issues.

May also have to do with what the silver pigment actually is, in that the first layer, once dry, may not provide a good mechanical or chemical surface for subsequent coats.

Or both. Or neither.

In any case, nice build. I hope it all works out perfectly on launch!

After a couple of false starts, paint, phase 2.

Love that paint job! I would love to something similar but now that I run trackers/GPS in almost everything the metallic paints are a no go. I did just recently do a conical transition piece in silver since no electronics there. I love that metallic look.

My Level 3 uses the same paint and the Eggfinder works just fine in it.

Interesting. I've always heard that metallic paints attenuate the signals. I might have to experiment and test that. Good to know!

That can be true, but is not always. Like you said, test it and make sure.

Epoxy for eye bolts and charge wells, and epoxied the bulkhead into the nose coupler. The eyebolt will also be the bolt holding down the GPS sled inside the nose.

No problem for me with metallic paints, either.

I think this is one of those TRF legends that may have happened one time 25 years ago, but never again. One poster in particular repeats this warning over and over.

Spent some time with a set of metallic paint markers today.

I did that yesterday, except I used paint brush’s, I like the hand made in a garage look they gave (at least when I use them!)

Ps and I have worse hand writing!

I’ve been following your build as I have a Wildman Jr. and am considering getting the 2nd stage upgrade. One thing I’ve been trying to understand is the wire routing for the sustainer starter. If I understand correctly, the Ematch wires are connected to the appropriate channel on the altimeter in the sustainer. From there, they travel out the aft end of the electronics bay, through the sustainer body and into the conduit. Upon exiting the conduit, they make the 180 degree turn and the Ematch head is placed into the motor as usual. That all makes sense. Where I scratch my head is that those wires are passing freely through the same section of airframe that contains the drouge chute and recovery harness. What keeps the wires from fouling the recovery gear? My apologies if I am missing something obvious. I’ve never done a two stage with electronics and really want to understand all aspects before I dive in.

You can tape it to the side and you put the break wire just under the ebay.

Pretty much this.

Took the paint markers to the booster.
