Happy New Year everyone?

One of my 2004 projects is going to be my first dual deployment rocket. I'm going to start small with a four engine D or E cluster based on Estes BT80 tube. I'm planning to use tube coupler stock for the altimeter bay. I haven't yet purchased the altimeter yet, so I'm unclear of their various dimensions and weights.

My questions are:

- How long does my altimeter bay need to be for the commonly available dual deployment altimeters?

- Can you give me a weight estimate for an altimer bay?

Thanks for any help you can provide!

I recently finished an altimeter bay for my LOC Legacy. It is 1.5" in diameter and 18" long. It weighed in at 4.5 oz but I used a lot of epoxy. Attatched is a drawing of my setup.

MetMan, I made a altimeter bay for my Aerotech Warthog..... I don't plan to use it for dual deployment, just to report max altitude...... (I believe it is the same diameter as a BT-80 (OD 2.64")) ......... My bay is made from a coupler, with 3/16" plywood bulkhead and 2 section of "all-thread"...... The coupler is 5.5", but the overall length is 7.5"..... I used pretty heavy hardware and mine weights 7.1oz without the altimeter sled......

Here's what mine looks like......
