Photos of base anchors, let's see'em.

i do 3 truck traps then a running midline bowline. with 3 wraps, i can leave the last wrap where my bowline will be somewhat slack, enough to where you could untie the bowline while weighted. i can do a whole climb and come down and it will still be slack enough to untie.
and you can lower me off the trunk wraps if need be, but id have to be pretty f'd up to let you do that to my climbing line.

im all set with these set ups that introduce flop, like a porty. if i were to use a rig or something i would probably want to do one trunk wrap to see if that limits the flop potential. or use aaron's solution.

Trunk wrap way is the way I like ,not much more simple yet effective than that. Its primitive ,but sometimes thats the best . No matter which way you go as long as the lowerer understands the system, that seems the most important thing .

Really?

Well, OK, if you say so.

No really think about it. The tail of your rope lays all over the ground. How much could go wrong and what are the consequences if that rope gets bound up, gets a knot, gets sucked into the chipper? So I trust my ground crew to put it in the bag. They could instead, cut it, tie it in knots, pile wood atop, run it through the chipper.

How different is that than trusting the ground crew to add or subtract rope from my system with an adjustable basal anchor? Could they lower me right out of the tree at will? Possibly, but it's harder than you think, we have tried. Could they cut my system loose? Sure, but that could happen regardless of basal anchor. Wood? Knots? Other assorted craziness? Of course, but all that could happen with any system.

I am not suggestion that anybody just come by and "F" with my base anchor, but training, then asking a ground crew member to adjust it for me is not a big deal. No bigger than putting rope in a bag.

Albeit, I do not know the quality or number of your ground crew or the ferocity neighbor hoods you work in. Those would definitely be a factor. With out competent ground support I would adopt your attitude. Well some of it anyway ;)

For the record I have no real problem with a running bowline as a base anchor. I just think using it can be limiting in many ways.

This is one I use a lot. Pardon the "tree". I take two or three wraps round the trunk, then pass a bite under the wraps, tie a midline knot, and attach to the standing end with a screw link. The link can be taken off and the knot untied, then the wraps are used to lower. I have been lowered with my rope thru multiple junctions. The wraps can be added or subtracted. No whistle test, but if the rope is dropped you are in for a slow ride down.

You can attach more rope as long as the attachment will pass thru the junction.

. Snake Anchor, Rig, two locking carabiners…I will pull out enough line to work on, the rest stays in the bucket at the base. 200 feet of rocket line just stuffs into the bucket. on a bigger tree I use a second line tied to my working line just above the rig. Similar to what PA countryboy setup on a video a while back.

The problem with tree wraps for me is many times I cannot damage delicate bark, attached ivy, birdhouses, those stupid face things w/ accompanying screws, etc.

My other hesitation is the same reason we don't use them for rigging, not consistent enough.

Because I tend to use them for more than just emergencies, this is a real concern.

My coworker lowered me down on macs set up in a European birch yesterday, obviously this will vary with species but had way too much friction. What I do like is that the wraps are already there, easier to take them away than add them, and also that the delta was fairly easy to release
 
Tony,The wraps are only going to be doing damage in the case of an emergency. I am alright with that. In an emergency I would spike the tree if I thought it would save a life. I would break into a house to use a phone, or medical supplies too. All bets are off in the AR or just R scenario

I hate those stupid face things. And I acknowledge that every tree is not a candidate for trunk wraps.

Tony, you should post the anchor you showed me at expo. That's a good one

You can put enough wraps around the trunk so you will actually not move at all, tied off or not. And it is easy enough to walk a couple wraps off. And the worst I've had the delta be to get off was only a slight pain in the ass. With more wraps you can make it so the delta is very much unloaded.

I like the wrap method best, but trees with all sorts of stuff noted above can make the trunk wrap method suck and big assed bushes ! Like this one .

Mac,

I am with you in an emergency. Just that we tend to add rope often.

Also, we have had the trunk wraps "creep". That is to say as the climber loaded the anchor,the wraps tightened, displacing some stuff that ought no be displaced!

Again, I am all for a functional system with forethought, only pointing out what we discovered.

As for the pics. I am working on it, but family time is taking priority!
