A friend contributed to the:
Reboot the Suit: Bring Back Neil Armstrong’s Spacesuit
A community of backers around the world came together to help the Smithsonian conserve, digitize, and display Neil Armstrong's and Alan Shepard's spacesuits.

(still active) Kickstarter campaign launched by the Smithsonian Institution.

He asked me if I would 3D print scans of Neil Armstrong's glove.
The half scale glove is 6in tall and full scale is 12in.
My relatively thin hands were able to fit inside the full scale part.

Printed each glove in two parts. Filament deposition 3D printing process works best printing forms that start with a wide/thick base and get smaller/thinner as part goes up.
The inside of the gloves were also accurately scanned, and included a mounting collar at the wrist for joining to the rest of the spacesuit. So I split the model of the glove at this "wrist" point and that was the bottom of each printed part. Then bonded these two parts by painting with acetone and joining them.

It will take some sanding to reduce the layer banding created by the software and printer's difficulty matching the fine detail of the high-resolution scan.
The full scale glove is the heaviest and most detailed part I have printed so far at 17oz.
Small glove took about 3hrs to print and large glove about 30hrs.
Fun and cool, but not quick.

Both my friend and I thought that there was odd-roc potential for Neil's glove...

Put the glove on a couple existing rockets for fun pictures.
Inclined to make odd-roc just the glove with a minimal (black?) fin structure below it.
For this purpose, I would want to print the full-scale glove with the same detailed exterior, but thinner walled / lighter weight, and internal form modified for rocketry.

When I saw your first post about this, I immediately thought "oddroc!"
 
First Annual October Sky launch
RIMRA / CMASS / CATO - N. Kingstown, RI - 10/8/2016


Nice weather for this time of year. Comfortable temps and moderate winds all day.

Fairhaven, MA TARC team:
1) smiling and 2) action pose
3+4) rocket lifting off quickly on F59

Team got some good flights off and continues fine tuning..

My first flight was the Seis: 24mm FlisKits Tres +3 motors.
Loaded with 3x D11-P + 3x D12-5 only half the motors fired for a hard recovery.

Clustered rockets and igniters flown today had been prepped a couple months ago, but due to a conspiracy of weather, technical and scheduling issues not flown until today.
Meanwhile they were exposed to some humidity and handling...

Rocket will be repaired. Said that too many times this year...

Next up was my VooDoo Daddy
Firing all 4x D12-5 + 4x D11-P motors
also used a Jolly Logic Chute Release for the first time
Nice flight

Next couple pics are another flier's Rickter Wrecker off to a good flight

My last flight of the day was the MadCow Bomarc.
Firing all 6x D11-P + 4x D12-5 motors for a great flight.

Then Al Gloer's Warlock roared off the pad on an AT J350 for a good flight.

"pic 2: Prepped flashpan"

How is this done? Is it just filling the motors nozzles with bp or do you attach bp to a hex shaped patch of masking tape with an igniter attached?
 
- lay two crossing layers of masking tape to cover gaps between motors but leave nozzles exposed
- fill each nozzle with BP
- lay a grid of quickmatch, with one end protruding to receive igniter
- lay two more crossing layers of masking tape covering all

After doing this more than a dozen times, can complete all motor prep in about 1.5 hours.
Then at the field, final prep time is similar to a single engine flight.
 
CMASS Launch - Amesbury, MA - 11/5/2016

Weather was moderate, 50's with very light winds for most of the day.

First up was the Pink Flamingo on a CTI G68-6 White.
Put a pink flamingo adorned nose cone on the Canadian Arrow and launched from a HP pad just in case...:shock:

Flight was quite stable to start, with a slight wobble as it was arcing over.
First flight for this combination of flamingo NC and rocket body.

Used the JL chute release, but it was not needed with these light winds.
As a result of packing the chute too tightly and setting the chute release too low, the recovery was fast and one fin will require modest repair.

Then the HellBoy went up on 19X D11-P engines.

Lots of smoke behind the relatively quiet hiss of all those BP motors.

Pic 1 is the flashpan just as it makes a quiet pop sound and kicks off the fun.

Then the Spinning Saucer of the Apocalypse lifted of on 2x G64 + 8x D11-P engines.

Climbing out of a big smoke cloud at the pad.

I love the way the flame trail gathers under the Hellboy with all those BP motors going! :clap::cheers: as usual!
 
Thanks. The smoke/fire/sound effect of the HellBoy is a lot of fun.

Dang, I thought nothing wood beat the footage of the Hell Boy at ignition...but how about on board video from a spinning saucer? AWESOME!
 
RIMRA - Kingstown, RI - 11/12/2016

Another nice day, light winds and moderate temps.

My first flight was the VooDoo Daddy on
4x D12-5 + 4x D11-P

new Jolly Logic Altimeter 2 reported
Apogee: 833ft
peak speed 162mph
peak acceleration 10.2Gs

IMG_1309.jpg

Then the Bomarc lifted off on
6x D11-P + 4x D12-5

JL altimeter 2 reported
apogee: 533ft
peak speed 115mph
peak acceleration: 6.1Gs

More data is fun
This altimeter reports a lot more data and has a well designed use of one single button and small display

Rockets after their flights
All motors fired

The Bomarc is quite low and slow, helps keep it in great shape after 6 flights
May load central E9-6 motors when conditions are favorable going forward
