I like the break it down part after its use. I think for $50.00 2″ polyisocyanurate at home depot is about the most practicle solution. Now you know why roofers just call it ISO. Used widly in commercial roofing.I do…   Read more»

Forgive my spelling errors. I proofed my comments three times and after I posted it I got so damn mad at all the errors I made of desire to remove it all together. Probably the biggest error was posting these…   Read more»

Three thoughts here. None of them may be practical for your purposes, but they are just ideas that may germanate into somehting else. At the helicopter shop where I was employed, a friend of mine who ran the composite shop…   Read more»

I’ve been thinking of getting the foil-backed foam from Home Depot and making a real oven, but I haven’t needed to do that yet.Well I guess I will be building one this weekend. Foil backed iso.I have a 20000 btu…   Read more»

Old school ovens for curing rockets were refrigerator boxes lined with aluminum foil and a few 100 watt light bulbs suspended inside. Properly sealed, you’d be amazed at the heat produced. Otherwise, Art had access to two large autoclaves but…   Read more»

Chris, as always you are right – or at least righter than I am in the explanation. It is related to the combination of airframe diameter, fin root chord length and semi-span. I still haven’t found the email with the…   Read more»

Warren: I’d be curious to see a reference for that (the interference drag). Everything I know about interference drag (which is admittedly not much, but it at least includes the basic mechanism) and boundary layers (about which I know far…   Read more»
