Mars Lander - Scratch Built - 3" Nominal Diameter

Launch Lug and Spool Modification

Notched the spool rear centering for the Kevlar shock chord. This will allow routing the Kevlar from the external lugs down into the spool.​

Foot Pads

A new pair of shoes..... I cut these on the wood lathe and then drilled (3) 3/8" dia. Forstener bit holes in each pad for the legs / struts.​

And that last couple of days of snowfall really filled up Mt. Princeton. That likely means some quality launch time ahead.

How many birds do you have ready for maiden flights?

14 20 ish Last years burn bans have really put me behind. ​

Gonna be a busy day!

Do you preload your birds (wadding when needed, chutes, motors sans igniters) at home before heading to launch site?

Motors, yes. Chutes, maybe. I reuse a lot of the chutes, they're all in disconnect swivels.​

Updated As Built OpenRocket Simulation with Recovery Anchors

Hadn't thought about the foot pads, I'm guessing the help out the CP a good bit. Also suspect the cost a bit of altiitude, but it's a SPORT ROCKET.

Stable VLEO* achieved!

No hesitation on that one at all.


*VLEO Very Low Earth Orbit

More like LRO

As in, LakeRoadster Orbit

Spar Urethane Gloss

Bought a quart of Spar Urethane Gloss ($22 ) and applied a couple coats to the Mars Lander.​

That bright wood finish could almost justify a steampunk treatment, though I'm not actually into steampunk. Will look good either way. On the next one, I suppose it would be destructive to use wood from a bonsai that's at the same scale as your model. Just to get the grain on the right scale. ;-)

How does it do for grain filling?

How does it do for grain filling?

Pretty good. Keep in mind though, there's no Balsa or Basswood, it's all pine.​

 

[Daddyisabar]

Who needs expensive hardwoods like balsa when the backyard is full of pine. Money better spent on BIGGER MOTORS!

High Temperature Paint

Shot some Rustoleum High Temperature Paint on the tube extension and centering ring that will get the brunt of the ejection charge.​
