THIS IS A BETA RELEASE - This is an initial release for final testing. While every effort has been made to ensure proper fit an function, I ask additional patience while I make things right in the unlikely event something is amiss. These ultralight 6061-T6 aluminum canisters are threaded to be...
They are now available for sale. I have the 3g finished, Feel free to order the 3g and put 6g in the comments and I will ship when available.
These ultralight 6061-T6 aluminum canisters are threaded to be sealed with standard low profile water bottle caps. (1.05" diameter, 1/4" high, 3 thread starts)
Each weighs in at a impressive 4.4grams empty, with an additional BP capacity of 3g sufficient for most 4" and 5" rockets.
These canisters (with cap) are 1.05" Diameter, and 0.453" high
The canisters have a threaded hole on the underside for a standard #6-32 screw for attaching to your bulkhead.
Each canister comes with one cap and stainless steel screw for mounting.
There are (2) ways of routing e-matches into the canisters:
For BOTH options, remove 75% of the e-match protector so the tip of the e-match is visible, but the solder connections are covered and prevented from shorting.
1) The easy way: Cut, drill or melt a small hole in your plastic cap. Feed the wire through the cap with the e-match on the inside. Add powder to the canister, and screw on the cap. If the wire hole was tight enough, you will not need anything additional to seal the hole.
If you are prepping ahead of time, you can seal the area where the match goes through the hole with epoxy, silicone, or hot melt adhesive.
2) The slightly less easy method: drill a 7-64" hole through the bottom of the charge canister where one of the small pilot holes are. You can fish your e-match wire under the canister before it is screwed to the bulkhead. Seal with silly putty, silicone, or hot melt adhesive if the wires are not a tight fit through the hole.
This is a cleaner looking install, but takes more time and requires access to the underside of your bulkhead to remove the charge canister each flight.
Environmentally friendly note: making a tiny slice in the center of the cap makes it split in the middle and stay with the holder for removal after flight.
