    Shoe Storage Made From Cardboard Pipe

    Getting a clean cut is THE trick. You will probably want to leave the factory edge out and bury the cut edge no matter how well you do it. It can be cut on a line with a razor knife, but not easily: be patient and don't use force. And a cut is only as good as your line. A skillsaw or sawsall will cut it, but you will have to clean up the edges somehow. With concrete forms, a perfect edge is of zero concern. For finish work, I would use a skillsaw or table saw and figure out a guide or a jig. If you figure out how to duplicate a factory edge, please let me know. I don't think they make pipe cutters that big, but that would sure do it.

    cammosutra a few seconds ago Yeah, I WOULD paint the cuts. For the record - - these things are called sonotubes. No clue why, so don't ask me. But if you show up at a Home Despot, or Less Of What Eagle Sold (LOWES), or wherever, they are in the section with the concrete stuff and that is what they are called. The trick, in my experience, is getting a perfectly perpendicular cut, and they are to big for most chop saws. The are used for forming concrete columns and are usually just left there: if you strip them, they will come off in a spiral or in chunks. They suck up moisture and go to Hell, if they get wet! I would paint or re coat for this use. Cool stuff. Have fun!

    I should add a PS. A BIG PS. This is heavy duty cardboard with center full of air. It is flammable! A sonotube can catch fire and burn in this sort of application. Don't put it near something that can set it on fire or voice versa.

    Unless I misunderstand something , your titebond "improvement" is not waterproof. And that is the weakness of these: if they get wet. I have worked with those tubes on concrete pours. No offense, but you apparently have not. If you don't think they are tough enough already, I have to ask: what in Hell are you planning to do with them?

  • How to Survive a Backpacking Trip in Alaska

    Ditto the comments on firearms here. If you wound a bear far in the back country, you all may wish you never had. At least one can of bear spray per person. And probably some extras. Also, be aware they have a shelf life. You will want fresh ones. You will need to know how to use one fast and they are no good in the bottom of a pack! I write the purchase date with a marker on the bottom of mine at time of purchase. In Montana, the recommendation is do not sleep within 100 yards of your cooking spot in Griz country. Probably good advice in Alaska too. Keep food smells off your camp gear. Bears have incredible sense of smell. Camp upwind of your kitchen, and hang your food well if you can. That means have some line in your gear. And knowing how. Don't be half assed on this one!One the ...

But if you think you can overcome an adrenaline rush, get a weapon up, chamber a round, and shot a fatal shot as a bear is charging you from 50 yards in a very compressed time frame, I wish you luck. A firearm is probably better for warning shots, or emergency signals if you are really in a jam. 3 shots (or a lot of 3 other things like small fires) is a universal distress signal. Worth knowing. You might have to help somebody as well. You are going far enough off the grid you cannot count on your GPS, a cell phone, or quick help. Keep that in mind. Have a map and know how to read it! There are also a few distress signals you can make on the ground that can be seen from the air. Worth knowing. Don't let any of this scare you from an adventure of a lifetime, but know what you are getting into.
