Bad thing is it needs to be cured in an oven.Any body have an oven 6 feet long?I do but it does requires assembly. It is regulated to 210F and has internal fans for forced air heating. The heated chamber…   Read more»

By the way, I use the PartAll for all kinds of things. Even when I’m gluing in a t-nut to the inside of an airframe, I add this to the screw that holds in in place just in case some…   Read more»

I wouldn’t trust my nest egg to Vaseline. I would splurge the $17 and buy some High Temperature Partall. Even the low temp stuff is only $13. I’ve been using the same tin for nearly a decade and still have…   Read more»

Now all is needed is a simple solid state guidance system.I’ve got one, at least an anti-roll system that I’ve been working on for quite some time. I’ve still ground testing but it looks very robust and reliable. I plan…   Read more»

I found a 1/4″ piece 24″ X 48″ online for $160. A little more for balsa core. I didn’t see 1/2″ thick but that is where I bought mine from.Doug

I use the PRO-SET epoxies because in addition to different hardeners, they also offer resins of different thicknesses. I prefer their 125 Resin Low Viscosity for everything and always add fillers to thicken it up to desired consistency. By using…   Read more»

Since the pictures were taken, I have moved to masking tape instead of the electrical tape. I’m more lazy than environmental and cutting all those little pieces of tape was too much work. I got an automatic tape dispenser from…   Read more»

Here is a couple of pictures of Z-fold

Since Art didn’t include all of us, here are some shots with James as well…Odyssey weighed 230 pounds at liftoff and flew to over 16,000 feet and just over Mach 1.Doug

That is one of the rarest airplanes every built – only 2 were ever made. from http://en.wikipedia.org/wiki/Lockheed_U-2 the different versions of the U-2:U-2B Two-seat trainer; J57-P-31 engine; five builtU-2D Enhanced two-seat trainerU-2CT Enhanced two-seat trainer rebuilt from U-2D airframes with…   Read more»

The dates for BALLS should be announced by then (annual meeting). Unfortunately it probably won’t be announced by then. At least if the last few years were any indication. In fact this year they changed the date (to OF weekend)…   Read more»

Don’t know if this makes a difference, but LDRS is in June next year at Lucerne. Also, don’t forget at NARAM in Pueblo in August. So many choices…Doug

Heres a link to another carbon tube maker. I have bought nothing from them.http://www.carbonfibertubeshop.com/large%20tubing.html

I have bought from them but not the pretty stuff. I was happy with them and their product.Doug

it has ALWAYS been a function of programmer bandwidthWarren quit being such a nay-sayer and pull the crap out of your ears and open you mind. The AP Bonfire contest does NOT require “programmer bandwidth”. It never has.we’re trying to…   Read more»

Why are you avoiding the issue? Although the post was originally under the launch logs topic, both Scott and Edward were asking why the AP Bonfire Contest does not accurately reflect what they burned. I brought this up last year…   Read more»

Yes, I’ll be there, except not as far out, right Joe?Doug

I just don’t want to get hit by one of your hose clamps falling from 10,000 feet. I’ll be more worried about being hit by the rocket attached to the surgical tubing that was sealed with a tie wrap that…   Read more»

I prefer the thicker walled surgical tubing. My way of thinking, the higher the bursting pressure, the longer is had (and higher pressure) to completely burn the powder. I get mine from McMaster and I typically use 3/8″ ID 1/8″…   Read more»
