"The steel U bolt was flattened", wow that's some serious force (and obviously pressure).

Here's an image I'm guessing you guys have never seen: Abort motor test fire in Utah, 2008

I think that is entirely disproportionate. The telephoto effect makes the LAS look way too big.

Pretty smooth finish. Still no steering nozzles, but it can’t be perfect. Very nice.

I have some spare tent stakes that I use. Sometimes the ground is pretty hard though so I always have a claw hammer available.

Include a photo. I can’t figure out where the J bolts go.

Why are the steering rocket nozzles missing?

Congrats hermannj! well done!

Hey Tom Keith, I too am considering making a L2 attempt with MDRA some time in May or June. Perhaps we’ll see each other at the Sod Farm. Later, Tom

There is a new bulletin published by CTI just recently (April 15, 2019) strongly recommending a modification trimming the “ignition pellet” in half (actually 40%) because their 3rd party manufacturer made the pellets incorrectly. I’ve got 3 G60s that I will need to modify at the range before...

Cool, I'll stay tuned.

Russ, can the RF connection remain during flight, or is it only before and after flight while the rocket and iOS device are stationary? It sounds like the latter, but I would love to see real time data. Tom

Thanks for all of these. I think I have decided on a design (which I will post once assembled). Thanks again for all the images! Slothead Tom

I like it jnobels. Thanks for sharing!

I like that rail in the background too! :)

I'd like a few more photos. I'm sitting here looking at mine (just picked it up from Home Depot), and while I like the general idea, there seem to be lots of different methods to use it. The first problem that I questioned was how to attach the 1010. I saw the photo of the carriage bolt and I...

I’m now thinking that I could use a fly-away guide, but that doesn’t answer your question. Here are a couple images I took a little while ago, and they don’t help extensively because they are on a 3” body tube. In answer to you question I think I could live with a 0.1” to 0.125” spacing if you...

Lately I've been using the extruded 1010 aluminum rail guides (see image below), not sure of exact dimensions, but I've used 1010 Apogee buttons before too.
