Bollard design

[stig]

With gas prices what they are, Volvo will probably start making miniature hybrid cars soon like most other car manufacturers.
Then we can all take Volvo sized pieces down.

I've never had the Hobb's try to run up the tree to meet the climber either.

As stated before I am paranoid, but there aint no way Im going to cut a 1" deep cut into a tree Im about to climb. I would however drill a 3/8 hole and put in a 1/2 lag bolt, that should keep er put IMO

You'd worry about a 1" cut in a tree?

 

[stig]

He said he was paranoid!

 

[lumberjack]

And he has a habit of climbing some less than ideal trees.

 

[Marc-Antoine]

If I can't cut a 1" kerf, because the tree lacks of sound wood, sure I wouldn't trust in a lag bolt.
Sure enough too, I wouldn't climb this tree, without speaking of rigging.

 

[Burnham]

As if Ed never did the same, or worse...

 

[Thor's Hammer]

Meh. Trees are stronger than you think

 

[stig]

So are you, apparently.

Or you wouldn't have survived those trees.

 

[Burnham]

I rest my case .

 

[PCTREE]

There I rest my case Ed, that tree was hollow to start with, the fire didnt make it so. Would you feel good about making a 1" deep cut in that tree and then climbing and rigging it. Plus that tree has a lot of sound wood compared to some Ive done. Im not trying to show how big my balls are Im just saying I dont feel that its a good practice to get into to further compromise a trees strength before climbing it. I agree trees are uber strong but we have all cleaned up the ones that go over........

 

[flushcut]

I don't think I would have rigged off that tree. Last year my buddy rode a tree to the ground and has just learned to walk again. It was a hollow oak that he was rigging off of and had more sound wood than that. I myself like to play it cautious.

 

[Burnham]

Old climbers, bold climbers, fewer by far that are both.

Idea hit me for a large bollard material as I was driving by the metal fab guy in town.. He has what appear to be two older aluminum street lamp posts. Huge plate on the bottom set up with 4 holes at the corners and the junction port is all of 8" up the pole from the bottom. Probably 6-8" diam tube.. Not real tall, probably came out of a parking lot...

 

[Burnham]

Wonder if the taper would cause the rope to pile up against the bollard arms you'd put on it, causing extra friction, maybe even binding it up?

They used to say that about ironworkers also .

 

[Burnham]

Lots of the same rules apply to both games...gravity being foremost among them.

 

[lumberjack]

How heavy of rigging would you be taking on a tree like that though, Paul? Just because it has a visor doesn't mean you have to use it (unless it's welded in place).

 

[CurSedVoyce]

Burnam, the bottom of the pole had so little or no taper, I doubt it would be an issue. The rest of the pole... whole nutter story. You would only be able to use the bottom 8" on the one I saw today.

 

[Burnham]

Sounds like a real possibility then, Stephen.

 

[CurSedVoyce]

Now just what to do with the rest of the pole...
Barn light?

 

[flushcut]

Anything is possible.

I'm thinking with a pigtail of some sort at each end, you could use it just fine.

But now that I think of it, the PWIII has something at each end and it'd binded up on me a time or two over the years.

Nevermind- I just cancelled out my own post.

 

[Burnham]

Flagpole, Stephen.

 

[treesmith]

If it were mounted with the larger end toward the tree, with a fairlead to guide the rope, I don't see where "piling" would be a problem. The load end would be straight up from the end, while the working end was fed in from the outboard end. If the situation were reversed....now that might be a problem, as the taper would be toward the fairlead end. The Hobbs is somewhat tapered, is it not? Seems I recall it looking something like a spool.
