Shapeways Printing Service No Longer Available

As of July 2, 2024, Shapeways.com printing service has ceased operations. So until further notice, our Meatball Rocketry scale model parts will no longer be available. We are looking into other printing services and other possible solutions. We’re very sorry for the inconvenience. For information about Shapeways closing, see the following two articles:

John Brohm’s Javelin Project

Guest Article

We are pleased to be able to host a series of four PDF articles by John Brohm, in which he highlights the various construction and finishing techniques he utilized on his 1:10 scale Argo D-4 Javelin models. John’s exceptionally well executed scale modeling efforts and successful flights earned first place for his team, The Flying I-Beam Kids, at both NARAM-59 (2017) and NARAM-61 (2019) in Team Division.

Spectacular Failures of Unmanned Rockets

(Video)

I put this together for a 4-H rocket day camp in 2013–the kids really enjoyed it. Video clips from various YouTube sources, The Right Stuff, and Spacecraft Films DVD, Liftoff: Success and Failure on the Launch Pad (highly recommended). Audio track: Wagner’s The Ride of the Valkyries, performed by the Royal Philharmonic Orchestra.

Minor Site Update

We now have an e-commerce plugin handling the layout of our 3D-printed part links, etc.  This should make it somewhat easier for our customers to browse products that are available in multiple configurations while remaining on this site.  Links will take you to the corresponding product listing on Shapeways.com.

An added benefit of having the e-commerce plugin is that it will open up the door for us to add future product offerings as well as new 3D-printed parts.  In the meantime, products can be browsed via the new default shop address:  meatballrocketry.com/shop/.

Javelin 1st Stage — Air Power Park

Javelin 1st Stage (Honest John) Detail Photos

The following images of the Javelin’s 1st stage and adapter were taken by Josh at Air Power Park in Hampton, VA in 2003, 2004, and 2006.  Unfortunately, this display has since been removed from the park and (presumably) destroyed.

This display was of particular interest due to the lack of paint build-up, leaving the surface details fairly sharp.  Also, unlike the Javelin display at GSFC, this Javelin includes the appropriate launch lug configuration (minus a stand-alone lug at the bolted region forward of the nozzle).

4-H Rocket Camp 2013 & 2014

July 18-20, 2013 and July 1-3, 5, 2014

104924 During the first week of July, Jess and I taught a 4-H rocket camp for the second year in a row, and it was a big success.  This year we had three days of classroom time, and with simpler kits to build (Alpha III), we had plenty of time to fit in extra activities and videos.  The only real downside was classroom size (basically a half of a trailer), which–thanks to better advertising this year–meant that there was a waiting list that was longer than the roster of students.  In addition to our two kids, we had seven total, including five novices.

We also had some time to fit in a few bottle (water) rocket flights this year.  On the first attempt, our foam-tipped rocket almost landed on a car in an adjacent parking lot, so we had to adjust our pad location.  Also, during a launch day demo flight my dad managed to land his Mean Machine in the middle of a pond next to the field (see photos).

Last year’s camp was only two days plus the launch.  We helped the kids build Baby Berthas, which was interesting to attempt with novice builders and only two days and other activities and information to cover.  We managed to get through it with the help of the 4-H leaders and adult-handled super glue for tacking on fins.  After both experiences we felt confident that it was a wise decision to go with the simpler Alpha III kits (NOTE:  Alpha IIIs do not come equipped with engine blocks; we recommend that they be added to ensure that the rocket last longer).

Some photos below are our own; many were previously posted on the local 4-H Facebook page.  Special thanks to 4-H leaders Krista Gustafson and Jackie Jeffris for all their help.
