THE ELECTRONICS BAY AND PAYLOAD SECTION


These are the basic parts for the electronics bay. I used 1/4" threaded rods. I replaced the original bulkhead with nice half inch bulkhead for extra strength. U-bolts are 1" in size. The Coupler (not shown) is double walled.	In this photo you can see the forward assembly of the electronics bay. The cup on top is a removable Ejection charge holder. I use a removable ejection charge holder so I could permanently install the forward Bulkhead of the electronic bay.	This is the removable ejection charge holder. It is made out of a female to female PVC connector and a threaded PVC connector. The threaded connector is cut to length to fit onto the 1/2" bulkhead. An O ring (not Shown) will be placed between the cup and the bulkhead to seal the bay from the ejection charge gases.

In the cup I will have two davey fire matches attached to different altimeters. The cup will hold up to 11 grams of power. I will only be using 6.5 grams to remove the nose cone during flight.	Here you can see the inside of the electronics bay. I tried to keep it simple.	This is the electronics board. Two RRC altimeters will be mounted on this board side by side and they will slide into the bay as shown in the last photo.

This is the aft end of the electronics bay. I have mounted two terminal blocks on the bulkhead. Each block will be connected to one altimeter. One match will run from each block to a single large charge, appox 10 grams, to separate the payload section from the booster. As you can see I have already tested it and it worked great.	I decided to use key switches to arm the altimeters. This seem to be the best method of arming the electronics. These are sturdy switch which snap into the "on" Position. They are much easier to install than the DPDT switches which were my first choice.	Here is the entire payload section. It stand 4 ft 10 inches
