Ok the Moderators not a Poop head any more, he let me in. 🙂

Get the tube, put a skin over it, wrap it all up and then start sucking like mad on the bag to vacuum bag it…. Tube is done! You may need some help with your lungs, but hey everything can’t…   Read more»

Awe Greg, I was just hoping to buy the tubes.I really just wanted to build a Rocket Like Mike Konshack does.Get the parts and be ready to fly next month. HmmmIf I had to make a tube What would be…   Read more»

Scott,Just a heads up on something. Remember me telling you about that plastics place down off Santa Fe & Oxford?????? I went by today and they have all kinds of supplies. CF and Kevlar sheets by the yard, CF socks…   Read more»

My apologies Scott, didn’t mean to offend. Just that after a couple years on the Composites Group, I’m a huge fan – least amount of off-topic bullshit and highest amount of info of any group I belong to including many…   Read more»

Scott, you are completely wrong about the Composite Rockets group and it’s moderator, Mick Kelly. After a recent spate of spammers joining the group, he has gotten a tad knee jerk about rejecting new membership requests that don’t include a…   Read more»

Good price, but it’s only .025″ wall thickness. So be careful what projects you choose it for – or add a layer.

here’s some 2.75″ tubes on Craig’s List..I know nothing about them or the guy..info only.Tonyhttp://santabarbara.craigslist.org/for/766025081.html

Go through Wildman or Liberty Launch Systems to get PR parts. They have much more pull with Curtis than an individual buyer.Ken

it looks like a 5 to 1 but this is what I found:Method 1: Rough guidelines by compartment sizeThis method is based solely on typical charge sizes for typical rockets. It’s a rough starting point for your ground testing. Simply…   Read more»

Warren, that’s not so easy to answer, however, if you check out the link below you may find something useful//rouse-tech.com/pdfs/CD3_Manual06.pdfOn page 7 there is a chart that shows the recommended size CO2 cartridge for the diameter of the rocket and…   Read more»

What are they equivalent to in terms of black powder? I have a 4″ and 6″ project on the drawing board and CO2 will have to be a major part of both recovery systems on both projects.Warren

Why is the good stuff always so hard to find???? I think they do it to us on purpose.Check this out, I found it on an electronics page talking about the stuff cotronics sells. http://www.cotronics.com/vo/cotr/Sounds to me like a pretty…   Read more»

IIRC Cotronics has a very short shelf life? I know I read or heard that somewhere…I haven’t found anything on ProLine products on the web. The paste is crazy in that it is what holds the Mongoose fins on -…   Read more»

Not everybody needs really high temperature epoxy, but if you do, here’s some more info on the Cotronics offerings:Cotronics has a black paste epoxy (4525) that may be related (identical?) to the ProLine epoxy discussed above. They also carry laminating…   Read more»

Anyone have an actual link to the paste version of the proline stuff? I can’t find it on Tim’s page. I like the sounds of it and would like to use some for the fins & motor mount on my…   Read more»

I would agree with John, the Proline wet out somewhat better than West Systems, although not so you’d notice unless you’ve used a lot of West Systems. I’d personally give it a try – with a scale it’s not much…   Read more»

Jeremiah, a bit of a complex answer – Mongoose and Blackbird kits come with a black “paste” epoxy. It is a ProLine product. I used the clear liquid in my build (also made by ProLine). Same brand, two totally different…   Read more»

Wildman carries a ProLine epoxy – is that the stuff you’re referring to John? He sent me some with an order and I’ve been afraid to try it because I have both Aeropoxy and West Systems.
