Most of the folks I know use cardboard ones. I have a rough set of them for HPR tube sizes made from regular corrugated box cardboard. They are easy to replace and you can lay them out perfectly with an…   Read more»

You get Mike Bennett to send me their calender and James Russell to send me the Tripoli Colorado calender and I’ll mix ’em in with ours and post ’em.Warren

Sorry I missed ya Conway. I had planned on staying up for Sunday, but I was exhausted and the bird I’d planned on flying on Sunday had a really nice bounce from a flight to near 10K when the main…   Read more»

Like I said, I have the 835cc tank. This would extend me down into the lower powered J’s, give me a spare valve and 2 fuel grains… Next build session for the Uproar, bring it down with you so I…   Read more»

I’ll consider buying it. I have the 835cc tank and it sounds like you have 435cc tank. Those grains will also be a K240 with the bigger tank and the smallest orifice.Warren

I paid for 7 and the upgrade to 8. I use 7 for most of my stuff because 8 seems to be over optimistic all around on sims. 7 seems to be right on vis a vis optimal weight simulation,…   Read more»

Chris, I’ve wrapped tubes from 3 wraps of .75 oz glass… worked just fine for F motors and I probably could have gotten away with 2 wraps.Warren

On the back burner is an upgraded weather section that includes all aviation weather reports – winds at altitude, jet stream, etc. All the weather is essentially Greeley weather by the way.Warren

Not a one… so far. I was thinking about doing it but got all caught up in flying my 4″ bird.Warren

Given the weather and strong potential for a fire ban after this launch, if you don’t fly your SSS this month, you may not get a chance until Oktoberfest… I’m not fully prepared, but I may take a shot at…   Read more»

I have flown 4″ birds up to 15# with Acme rail guides “merely” glued on with JB Weld.Warren

All I can say is that if you’re not using rails on birds with 38mm motor or above, and even 29mm birds, you’re not up to speed on current best practices. While the club maintains a bunch of launch rods…   Read more»

My plan is to be out there Friday night, Saturday, Saturday night and at least until 11 or 12 on Sunday.Warren

Hopefully you’re feeling up to snuff Conway… hoping to see you Saturday. When I met you a couple years ago, you were selling off all your rocketry stuff and I was just getting into it as a new BAR… If…   Read more»

Hell, before I discovered rocketry, I was a little basement bomber myself… making matchhead rockets in thin aluminum pipe at the age of 8… We ignited them by heating the aluminum pipe with a propane torch… didn’t know anything about…   Read more»

I use an abrasive cutoff wheel on my chop saw. You and your dad are welcome to come down tomorrow and chop whatever you wish. It works well up to 4″… above that we have to get fancy.Warren

So many good ideas… I like this one too… though we’d want to scale the weight of the object appropriate to the impulse… hope you’re feeling ready. See you next weekend Conway.Warren

Thanks John. I’ll look into it. It has happened to me before too. phpBB, the forums package we use, also handles the PM’s. We may replace it soon with something else. In the meantime, I’ll see if I can fix…   Read more»

hard to predict and depends on the foam, how carefully mixed, how much space to expand. Weigh the liquid before you mix it, mix and pour. You can figure the density by figuring the total weight divided by the volume.Warren

Sandable filler is probably 5 to 8 times the density of foam… I’m speaking of the Elmer’s or other sandable wood filler. I’m really having a hard time visualizing what the application is. You can send me a Rocksim file…   Read more»
