BT-55 Nose Cone Payload Bay

[mh9162013]

I like using nose cones as payload bays. Here's my latest version for BT-55 nose cones. This particular one will go in the Estes Bull Pup 12D that I'm currently working on.

The tubing is BT-20 and that "ring" is just an external coupler because I stuck two scrap BT-20 tubes together.

The black ring is the 18mm Estes screw-on retainer.

The white bits are made from styrene sheets.







Nothing fancy here, and I know I could have made the payload bay wider (using a 24mm tube, for example). However, I wanted everything to be as clean as possible, so I knew I had to use a motor screw-on retainer. I know there are metal 24mm screw on retainers would that probably just barely fit, but I kind of like the "paper-plastic-glue" asesthetic of LPR rockets and won't use metal on them if it can be avoided (I'm an odd rocket builder, I know).

@mh9162013 --

I like this A LOT !

Thanks.

-- kjh( gotta order an Apogee BT-55 Nose Cone to install a 29mm AV-Bay now )

I've never seen or thought of a screw-on engine retainer for a payload bay close out, and it's ingenious.

Thanks! But I have to admit that I got the idea from someone else. I believe someone posted pictures of their AV bay and they used what appeared to be an Estes 24mm or 29mm engine screw-on retainer to hold in their AV bay in their HPR rocket's nose cone.

The threads on inexpensive beverage bottle motor retainers seem relevant here.

I've already done that. Works well, but it's not as "clean."

Hi Solar

Would you have the links to that threads you are referring to at hand?
I am a bit hesitant to ask, as you are obviously a big fan of the search function (and rightly so) .
I actually made use of it but can’t find other ones than the one mh anyway has linked.
Thx!

I suppose I COULD do an Open SCAD nosecone AV Bay/ Payload designer. As I'm bored.......

Buy a rural property. It cures boredom.

Thanks Cape

That’s the one mh linked in post #6.
From Solar‘s post I got the impression that there are more of those.
Anyway, the idea got clear

Here's another example of the bottle-top nose cone payload bay:

Thanks again for the input!
