I'm actually trying to figure out the *downside* to blow-molded cones. Certainly, the NRE on the molds makes it impractical for smaller manufacturers, but they can do low-volume sourcing of balsa noses from the usual sources.

I guess I'm not seeing why this is a big deal. I've built plenty of kits with balsa noses and plenty with plastic, and I'm perfectly satisfied with either. Is it just the nostalgia factor?

The only downside to using a blow molded cone of new design is that I will have to spend money to tool it, which means it may never get done. If it's a part that is already is in use then I have NO PROBLEM getting a new rocket design to market.

Fair enough. I guess there's little or no NRE for balsa parts, but if you can't get'em in volume then it's moot.

Hmmm...(Thank you, John and Sandman)...I was just thinking about hardwood as an interim solution. I also agree regarding blow-molded plastic nose cones being preferable (until/unless rapid, mass-3-D printing becomes practical). Even now, blow-molded nose cones are made in sizes down to slightly less than 1" in diameter (Quest's new 25 mm blow-molded nose cones, which replaced their legacy MPC/AVI injection-molded ones), and I'd be happy with even smaller (BT-5 size) blow-molded nose cones.
