Mike, I have a 96" toroidal chute that DaveH used on his L3. Less than 15fps if you want to use it. Edward

I'll have some 1515 and 1010 single piece Delrin rail buttons for sale at MHM. They come in sets of 3 and include a machine screw and well nut to mount to your rocket. I'll have the Rigid Orange Box ...

What are the weights of the components you are restraining? On my 2.5" diameter L3 rocket I had to step it up to 6-32 shear pins to keep the nose from deploying when I separated the rocket. I'd star...

ALRECO has plenty of hockey pucks for forward closures. Graphite is hard to source locally. I get it from NAC Carbon. Edward

You don't need DOA in your propellant. It just makes it mix better and you get a softer cure. Here is something I ran a while back: 79% AP 200u1% Mg13% HTPB2% PAPI5% DOA1 drop silicone oil per 500 g...

Yes, it is in an ammo can. You have to bring your own fittings to your motors. The club does not have nitrous. Edward

This weekend and next weekend are packed for me. I'll have to set aside some time after that. Once we get semi-final weights (+/- 5 pounds) I can generate patterns and order the fabric. What altimet...

Looking good! How is the final weight coming in. I'm going to need to get a pretty accurate weight so I can do final recovery calculations. I'll find time one weekend to stop by and look at the set...

For something this big we'll want to use a bag. The parachutes open *extremely* fast and will put very high loading on the recovery harness if we let it free fall under the stopped chute. A deployme...

After talking tentative weights it looks like we will need three parachutes. One 196" and two 160". All are sized for under 15 feet/second descent rate. We will be using 75 yards of 66" wide ripstop f...

With the dry conditions out there (as evidenced by the many smaller grass fires) what does the USFS have to say about our activities under our permit? Edward

I'm very time limited this time around - I have a 3 year old who consumes most of my time on the weekends. Another question - what rail/guidance system are you using? I'm pretty sure I can turn any t...

The 120" chute can do 58 pounds at 15 ft/sec. If you want to go slower, we need to upsize the parachute. The parachute is ~8 yards of fabric. I'm guessing the parachute would be between 3-4 pounds....

It was *at least* 10 pounds. The good thing is we had planned and built a compartment at the very front in case we needed some noseweight. Edward

The 3 Dogs Rocketry Eye Nut Anchors are also a superb choice. I use those for my L3. Edward
