It wouldint really be any better than the Poris Teflon would it? Where did you get it ?Scott, it really depends of the surface you want. As Ken pointed out the Peel Ply leaves a rough surface and is intended…   Read more»

I guess I can assume that both FW and C both are/ or can be G-10?I guess I have made that same assumption as well. I know it has fiberglass and epoxy and the best way I found to cut…   Read more»

If you’ve worked with G10 you are probably already aware that toothed instruments such as saw blades, and drill bits, absorb almost all the heat generated since the G10 is such a great thermal insluator. So you burn up a…   Read more»

The drilling thing (on filament wound) is a mess. I have tried drilling at different speeds, types of bits, taping before drilling, etc. The danged delamination is a mess. I had to get the right tools but I don’t have…   Read more»

I use Hawk Mountain tubing, never PR. I found the quality is much better with HM and Art’s rocket is an example that many of you saw first hand. The PR tubing may be thinner walled which results in lighter…   Read more»

Here is a link to a charge test that I did indoors. Nothing like impaling a car but it did scare the crap out of us. It’s a large file, about 11M but it shows a 2.0 gm charge in…   Read more»

Hey Doug.. So what do you do and who do you work for. Just curious.. Conway, you must have missed the link I snuck inhttp://www.nrao.edu/ I work as an Engineer/Technical Manager but there is a huge variety of jobs from…   Read more»

Joe, if you’re willing to relocate, I’ll put in a good word for you where I work in NM. I’m always trying to recruit fellow rocket people in my area. If you, or anyone, would be interested drop me a…   Read more»

Wish I could’ve seen Doug’s movies of that.

Bruce, you’ll have your chance at MHM ’08. I will likely just add the footage from Oktoberfest and XPC to the earlier footage and make a 2007 reel.Doug

I would like to thank Mike, Art, Warren, and especially Justin for their help with my equipment this weekend. I’ll apologize in advance if I forgot anyone, I know there were others. I really don’t think I could have done…   Read more»

It turns out that the one, and only, theater in New Mexico showing In the Shadow of the Moon actually starts this weekend. It’s only a two hour drive from where I live but since I have so much free…   Read more»

Warren, I’ve been trying to schedule seeing this movie in with my trip but I haven’t found a way of doing it yet. I would be interested in going but I would rather not try the 1:00 matinee on Sunday,…   Read more»

Thanks Conway, Yes, I’ll be here on Sunday, at least part of the day. I could always put it up in Little Freeze Frame and film it in flight. Art and I are discussing trying another drag race between Little…   Read more»

Thanks everyone, there were a lot more interest than I expected. Scott Harlow (sp?) is attempting his level 3 so I chose his rocket. I like filming the certification flights and I’m doing Justin’s as well. Both are expected to…   Read more»

That’s one of those little requirements. My rail uses the 1515 rail. I can attach a 1010 rail to the rail but it greatly limits what I can do… (I don’t have a liftoff switch for the smaller rail so…   Read more»

Thanks Mike but I think I’m set. Art is flying one of Conway’s motors in a not so retired rocket. I do look forward to your flight.Doug

Congratulations Art and Conway!!!

What manufacture? I have an AT if you need one.Doug

I’m curious why these wonderful contests don’t get much traction?or they wait for perfect conditions that never arriveI would like to see the contest to run for only MHM or Oktoberfest. John now that you live so far away, how…   Read more»

My preference would be to go with the thicker fins. However, the strength REALLY does depend on many different factors including, like Warren pointed out, the tubing you are using and more directly, how well of a glue joint you…   Read more»
