Thanks for the info Carl. And I agree with Made in the USA.

Maybe what we need is a heavier washer wieght that is dishes out that will still work with an eye screw. I have developed a way of hollowing out the BNC to install clay without messing up the coulper part of the cone, but it is not for beginner rocketeer's . Thanks, JP James Pierson NAR# 77907 |

Or you could make them out of plastic or basswood and include them in that deluxe kit (the fin fixture/jig/guide things).
I think that Semroc has it right, MADE in the USA and balsa nose cones. The balsa cones set up nicer, are very "fixable", I just think they are "better" overall. I deal with Russia, China, and India on certain parts for my work. If I could get away with not doing it, I would. But not many places that can stamp out a AK-74 parts set for replacement for so cheap and on the original machines with the original technical package. Quote:

The other thing I thought about, concerning plastic items, is the time-to-market delay. In the time it takes for one plastic tooling to be created, tested, revised, tested again, put into production, shipped, and finally received in the warehouse / packaging room, that Krellvenator could have produced multiple batches of the same cone and the kits could have been on the dealer shelves. The quicker turn-around time is worth any premium a balsa cone might cost, if there actually is any. I'm not personally in favor of an injection-molded cone at this time. We've seen some applications already on this forum -- the Tau Tau is a good example -- of where a hollow, blow-molded plastic cone might be usable; and if SEMROC did venture into plastic that is what I might suggest. But I think the balsa components give these kits a feel that plastic takes away. I'd just as soon not see plastic used right now. Estes and Quest are in that camp. Their QC is in dire need of attention, and off-shore tooling is just one issue. Let's just "not go there"...

In the past, a lot of the parts that came with the Estes original Designer's Special (which had stayed with me since the 1970's) also came in handy when I needed to make quick repairs/ rebuilds of my NAR contest "rated" models (especially the boost/rocket gliders and, on my most recent "overnight" build, an 18 mm helicopter duration model -- the Gassaway styled design). Speaking of which is why I need another "Designer's Special" as most all of the parts I had have been used up

I have small scraps of popular tube sizes already pre-marked for 3 and 4 fins. I socket the tube onto the body tube I need marked and use my angle stock to extend the pre-marked lines. Zip zip zip... done!

When I lay out my templates, I try to cut the slot width as precisely as possible, for just this reason. The tolerance on the balsa, plus the fact that I like to tissue the fins, means the slot width will vary slightly from project to project anyway. So making the templates out of matte board gives me something that I can sand to fit the width of the particular fins I'm using (also, the thickness of the matte board makes for a very sturdy template which makes for a better support). When the template gets too loose, I just make another one. Another reason to keep them cheap! And as has already been pointed out, it's highly advisable to chamfer the slot points to make room for glue fillets (!).

Excellent idea! It never occurred to me to do that, but I use scrap tubing for everything else.
