Re: Where to buy fibreglass cloth in Bris/Ipsw region?

Try boat builders in your area. They often have fiberglass cloth to sell.

Re: Cluster Duck

Looks like a nice build Derek! You could always call it "Cluster *uck" and then see what the LCO calls it out as! :D

Re: Horizon - 2 Stage Water Rocket

Thanks for asking Derek. I am just ramping up again after having a short break, I finally received my order (after 5 weeks) from Soller Composites which I needed before progressing. I've slowly been gathering materials to make the booster. I now have everything I need so booster production will be s...

Re: Lack of posts....

Shipping has also slowed considerably. It took about 5 weeks to get some carbon fiber delivered from the US (Soller Composites). Before covid it only took a couple of weeks. I was after some sleeves and plain weave 200gsm cloth. I wanted 6 meters of it, but they said they had a slightly narrower off...

Re: Lack of posts....

I too have taken a bit of a break due to less launch activity. I have started getting back into it again though over the last couple of weeks.

Re: Launch disappointment......

They should have invited a rocket club along to put on a show if the main launch doesn't go ahead. :D Do you think perhaps they had a short window, and didn't have enough time to recycle?

Re: When all you have is a hammer...

@Aquaman That's a nice fin can! Since you are printing it, could incorporate the launch lug into the base of one of the fins? It looks like there may be enough room along the fin's root edge between the fillets. You could drop a little weight and drag.

Re: Rocket tracker & monitoring thing

Very nice work on that Craig! It's been really interesting following this project. What kind of a range do you expect to get in the end when it is in the airframe?

Re: Hybrid question

Interesting article, thanks for sharing. For the mixing part I was originally thinking something along the lines of what abrasive water cutters do where they mix the abrasive into the jet of water just before it emerges out of the nozzle. But you could potentially get ignition inside this mixing cha...

Re: Hybrid question

Haha... okay, yup probably not a good idea then. :D I realize that trying to come up with some way of mixing the two just prior to injecting it would be difficult, it was more a thought experiment than something that may be practical.

Hybrid question

Do you think it would be possible to build a hybrid motor that uses a slurry of say HDPE powder and nitrous? If you could mix the powder and nitrous inside the rocket before it gets injected into the combustion chamber, would that work? The thinking is that you would have maximum contact between fue...
