Touring and tying down

If there are no rings in the asphalt, I usually use corkscrews. This year I have been to a couple of fields where screwing them was near impossible. Then you make a silent prayer for no storm that night.

When there are no tiedown rings available you should bring your own anchors. For different soil types you will need different types of anchors: The cork screw type is OK for softer grass fields but useless for hard stone loaded soil. For that kind the nail types might be more useful. So you need a decent hammer and VERY sturdy nails with rings for tying down . Question is, how long will all types stand vibrations and strain on them when wind forces are heavily changing force and directions. The folks at Avweb did some testing of various types, this could still be found there, I think. Vic

With this kind of capability I doubt a screw-in type tiedown would do much good

These

would just pull straight out of any substance into which a human could screw them into by hand.

This is the recommended method on ice

Am I right in that the dug out cavity needs to be filled with water and you wait for the water to freeze? That should be pretty good…

Just found the Avweb test:

@LeSving, affirmed. Exactly the same method is used by mountaineers for anchoring on ice when running short of ice screws.

@Peter, no, you don’t dig a cavity, you drill two thin holes intersecting at a sufficient depth below the surface, then run a rope through it. No filling with water, either, otherwise you’ll never be able to pull the rope back out.

They hadn’t tied it to three concrete-filled tyres.

Having difficulty in imagining how to thread the rope down one hole and up the other….
