[pct-l] Homemade Bear Canister

[reynolds@ilan.com]

I have tried to stay silent but this getting silly. Hundreds of thousands of
dollars have gone into reducing the weight of today's canister. Assuming you are
capable of making one yourself use aluminum, not plastic pipe and emulate the
aluminum can now on the market. If you make a plastic can it will wind up
weighing 4 pounds like the first model.

1-The original bear canister was made in the manner described except that it
used latches instead of a screw connection. The internal rings were 1/2". The
canister was glued together. This device weighed 4 pounds.

2-The second {Garcia} model used a single piece mold. Although it was the same
size it was considerably lighter and more secure. This was obtained by having
the bottom an integral piece [thus eliminating the inner ring] and by making the
opening less than the full OD [Thus eliminating the inner ring and reducing the
thickness of the cap. To create this model, Garcia invested $300,000 in the
mold. This model weighed slightly over 3 pounds

3-The third {garcia} model uses a two piece mold "spin welded" together. This
drops the weight to 2 pounds 12 ounces because the walls can be thinner.

4-The "BEAR CAN" is an aluminum canister. It uses internal rings to reinforce
the light aluminum sheet used in the CAN body and uses light sheet aluminum for
the top/bottom. The top/bottom are secured on the cylinder with four (4)
aircraft fasteners. It is obviously fabricated by hand. This device weighs 2
pounds 2 ounces.
