Genious! Thank you!

If you would reconsider the steel rod bound within the body tube. There is a description and pictures on my blog under the "Techniques" section.

Hopefully this can help, and at least bring you some rough numbers. Sorry I did not get it to you sooner.

It appears my post is being misinterpreted, I was saying to get the most accuracy out of any scale. You need to calibrate it, I understand for epoxy its not that big of an issue.

But in general...

The point is the mythbusters were trying to follow the myth as close as they can, the original story involved 1 JATO/RATO and a car. It did not involve fins, or a guidance system.

Also the...

If you would like measurements from the nosecone of the model and not the actual measurments please let me know.

I love watching Mythbusters, I found some of their safety features flawed. But they are very good at what they do, the mix science with television. It works out very well, and is informative...

Also if you want the greatest accuracy from a scale you need to calibrate it with proper calibration weights.

This is what I use. 200 by 0.01g.

Area66 if you will be witnessing the launch please keep us updated.

I updated my blog, including the build technique for shock cord attachment for minimum diameter applications.

Also I was thinking of the cable cutter to release the AV Bay.

I am curious what motor this will be flown with the first time, and the altitude it sims to.

I have some data on expansion of Aluminium due to heat. Im sure you can find it on the internet also. I will get it to you after work today.

You have been working on those fins for 6 years!

jk

I will have to pick one of these up someday.

Thanks for the history!

I saw that at OMSI a while back but did not know the story.

If you have specific questions that no one has answered please PM me.

I read this and started to tear up, I am sorry to hear about your loss.

As I prepare for marriage in a month, and reading stories like yours gives me hope for an amazing life with a loved one. As...

I am very interested in this kit, for the fin can alone. Please update as much as you can :)

Edit: and yes I know I can but the fin can alone.

I would love to participate do you accept PayPal?

I understand it is rough, but it will give some sort of idea the amount of pressure the nosecones can handle.

I think someone with the time and money, needs to perform a test on a fiberglass nosecone.

I can see a single motor mount or a cluster glued to the outside of the nosecone, then place one powerful...

Thank you for the update, I saw your post in the cable Cutter thread so I guessed it was from this rocket. That is why I posted in here :)

Hopefully everything turns out better for you, and your...

When will be the first flight? Or any updates?

Thank you for the replies,

I will be using the twist tie method, since heat is no issue I will also use some heat shrink instead of tape making for a better connection. The bulk plate will be...

In my mind, if the wire(s) get to warm while soldering then it can heat the pyrogen and cause the match to go off. But I might just be a little to safe in that regards.

You can solder an e-match? I figured with the low resistance and potential to get to warm that would not be safe? Plus with my bad soldering skills, I take to much time on one wire, which is why I am...

Just a thought, I am redesigning and rebuilding my Blackhawk rocket, dubbed Type II.

I want to redo my AV-Bay, I do not want to use terminal blocks as they will not fit to well on a 38mm bulk...

Kinda relevant:

I was thinking the other day, someone needs to make a rocket nozzle mug, so I have something to drink out of shaped like a nozzle.

I know :) just using calipers would be quick and easy.

If you use the Diameter of the motor and extrapolate the length of the flame with that you can make an educated guess that the flame on the longer motors is well, longer.

I left my calipers at my...
