Anyone want to share their thoughts on their favorite place to pick up the highest quality BT-55 Ogive nose cone? Buy plastic? Buy balsa? 3D print?
I've used both and like both. Just wondering if there is any supplier(s) that I am missing / not thinking about.BMS or eRockets for balsa. If you want plastic, the only place I can think of is Estes Assortments, or cannibalizing from other kits.
The ones I've received were turned so they would smoothly fit the Mach1 BT55 tubes, so you may need some tape to shim.I've never looked at Mach1Rocketry -- thanks for the pointer.
I will need a bunch, so I was just wondering if anyone had a prefered source re. quality and cost.
I didn't see any BT-55 nose cone available on their site....The ones I've received were turned so they would smoothly fit the Mach1 BT55 tubes, so you may need some tape to shim.
Hmm.I didn't see any BT-55 nose cone available on their site....
They have them. Blow moulded plastic. $4 and $7 shipping. Not sure on quantity.Hmm.
I'd call them. They have the better part of a dozen designs that are BT55.

I suspect they may sell the noses trimmed to fit Mach1 Fiberglass, if they have them, even if they have no BT55 Nose item on their website. I've bought parts from them in the past, including nose cones, but usually e-bay components. Whether they can handle a large order of noses, is a different question.
If they can't do it, let us know.
Blow-molded plastic, as I can use the inside of the nose cone as a payload bay. This seems to just be me, though.Blow moulded plastic or 3D printed or Balsa -- any preference anyone?

It depends.
Blow molded is probably cheapest to buy. Filling the seams can be annoying.
Balsa is probably available as a stocking item in the greatest variety of shapes. Filling the grain can be annoying.
3D printed has very low material cost can be anything you want it to be, so it's probably the way if you're particular about a design. But if you don't have a printer, it may get expensive. I'd also only consider resin at BT-55 size, not filament.
Also, kinda curious what your purpose is with this project. You don't seem overly particular about the design at this point. Why not just buy a bunch of PNC-55 packs from ACSupply? It has two each of the Cherokee secant ogive and Black Brant conical NCs for a good price.
And my axe!Blow-molded plastic, as I can use the inside of the nose cone as a payload bay. This seems to just be me, though.
???And my axe!
