Looking for a safe and convenient way to store and transport the black powder used for ejection charges, I found the Traditions Performance Firearms Muzzleloader Composite Tubular Flask with valve (black) at Amazon.com. It cost less than $15 and arrived in two days since I have an Amazon prime membership.
The flask is made of a hard, black plastic. It has a high-quality feel to it. The top screws off and it holds about six ounces of black powder. The flask has a button that you press that opens a valve allowing you to dispense just the amount of powder you need.
I usually use Newtons 3rd ejection cannisters or I make ejection charges using plastic wrap. In either case, the Traditions Performance Flask will make the process it easier and safer.
Getting accurate weights of individual parts is important when choosing a motor for a rocket and for modeling and simulating a rocket in Rocksim or OpenRocket. For larger rockets, especially, it is sometimes difficult to weigh parts on a flat scale. So, here’s something else I bought from Amazon.com and “re-purposed” for rocketry use. It’s a “Digital Hanging Scale” that’s commonly used for weighing fish. It’s small, a little larger and heavier than a deck of playing cards, and cost less than $20. I’ve found it handy for weighing parts of larger rockets and it’s small enough to carry to a launch just in case you need to weigh something onsite.
I’ve been on an organizing kick lately – trying to make storing and transporting my rocketry stuff easier.
Based on a suggestion in The Rocketry Forum (Gun case or reload case!), I ordered a Plano Gun Case from Amazon.com to use for storing and carrying my reloadable motor casings and accessories.The case has a foam insert that you can customize by creating openings for your motor cases and other parts.
The case was less than $40 and should be large enough to store my Cesaroni 54mm 6GXL and other larger motor cases. After I get it, I’ll let you know how well it works for me.
