Now I'm working on the charge connectors, I'm making 4 lead sets for this rocket. Each lead is a length of 26 gauge two lead wire, two connectors soldered on and some shrink tubing. With an 8-32 screw and nut through the connector

Here are the two drogue sets installed in the bottom of the bay.
The interior walls are shiny due to being coated with epoxy.

Here is what it looks like on the exterior of the bay.
Each lead now has a couple flat washers set between two nuts, once you go to install your e-match on the leads you place the stripped end of the lead on the screw post slipped in between the washers and then tighten the top nut. This gives you a good solid through the bulk head connection to your ejection charges with out the possibility of the burnt BP harming your altimeter(s). Also the charge wells are just CPVC pipe caps. I have a 8-32 screw holding each cap thru the bulk head. CPVC is stronger than PVC as it is used for water supply lines. It is not aluminum but it does hold up quite well to several charge events before you need to replace them, and their much less expensive than aluminum too.

You can see the charge wells and lead post here. As this end is towards the main chute bay I'm using bigger charge wells here. The Drogue end has 3/4" caps and the Main end has 1" caps. You can see that I have used the 1" caps once before. They do still have a lot of life left to them so I'm not worried about their integrity as of yet.

While I was at it I also soldered leads onto my key switches seen here.

I like using these barrel switches because they are durable and easy to use and install. Normally you need to drill a 1/2" hole and install them with a back nut. But I have found that if you drill a 7/16" hole you can start them and then use a crescent wrench to finish screwing them in. Of course you have to file a couple flat areas on the outer flange like I did on these to use a crescent wrench.

I will say this method works best with cardboard, phylonic, or thicker air frames. You will probably need to use the 1/2" hole back nut installation on thinner fiberglass airframes for these switches

Great pics Dutch I look forward to seeing that puppy fly. Thanks for the informational tips. You have always offered your knowledge and experience to the rocket community. Thanks for all you have done to help and build the rocket community.

As I mentioned before, due to the thickness of the airframe I was able to screw these switches in alleviating the need for the back nut.

So this is one of my sleds that are a standard build that fits most of my altimeters.

This here is one of my Perfectflite MAWD's, the tubes mounted on the sides of the sled are spaced to fit on the all thread that I have mounted in the altimeter bay.

I have most of my Perfectflite MAWD's and Stratologgers mounted on this size sled.

I have been needing to make new sled to fit my MARSA54L altimeters but I still want to be able to use them in most of my rockets.
So this is what I've come up with:

The battery clip is a standard 9volt battery holder

This following photo shows how both altimeters will fit into the altimeter bay.

As you can see here none of the charge wires or switch wires are connected, and neither altimeter is all the way down. But you should be able to get the idea how everything is mounted and attached from this photo.

So I know it was my intention to have this done by URRF 3 but I wasn't able to complete this by then so I guess now that URRF 3 has been an astounding success I guess it's time to begin working on the rocket again.

So we left off with filling the spirals with glazing putty and I have most of the air frame done as shown in this photo of the fin can/motor mount section:

As you can see I have one side and fins done here, I still have the other two sides to do as well as the main chute bay section. Once all the spot putty is done and sanded it will be time to apply primer and make sure I have all the spirals filled to satisfaction. When I'm happy with all of the rocket I will continue with the final painting.

So I'm back at it again, here I finally have the rest of the fin can spot glazed.
