Anyone else seeing this

I did the mod on my hand climber and put it on a tree this morning. Anyone else seeing the arm move in that much after doing the mod. I'm about 230lbs.

yup. you'll see that time-to-time whether the mod is done or not. Its just a matter of how much belt you have out vs tree diameter, or of the belt dragging on the tree and sticking to it as you draw up on the platform. If you have enough belt out, usually you can just do a tip-down and the belt will grab again the right way.
 
I put a coupler nut for the arms on the hand climber to come down against. Worked fine for me. I think I will order the longer traction belt for bigger trees. Placed my foot straps toward the front so I don’t have to point my toes as far down when I raise and lower the platform. Got plenty clearance on the traction belt that way. Attaches to my pack wonderfully.

It would be great to see more of how Mr. Formans build is coming along with his hand climber. I like the looks of the foot straps. Good idea getting rid of the bulky girth hitches.
 
After doing this mod, the arms do not rest flush on coupler nuts/bolt. Is this a huge safety concern? How bad did I screw this

up?

Is the hole drilled thru on an angle or to low. It almost looks like its to low causing the coupler nut to wedge into the original arm support area and angle up.
I haven't messed with mine in a week or so. I'm off work tomorrow so I will try to figure out whats going on with mine.
 
It looks like I did not account for the uneven surface on the inside. The bolt head is sitting over that surface causing it to angle like it is. I guess I will have to do a dance at 1 foot on it and see if it fails. Hope it will hold Me and gear at about 265lbs.

You may have drilled the hole a hair to far forward but it's fine. Try using a bolt with a smaller head. Remember, you can use a hex head bolt. That will allow you to turn the bolt head to the flat spot, flush against the platform. That should get you a couple millimeters. It's nice when things come out perfectly clean but it's not necessary. My bolt mod is just a stopper for the arms. It won't dig through the arms, they are thick steel square tube. I think the smaller hex head bolt will fix it.
 
I think mine flattens out with a tiny bit of flex when weight is on it.

Keep in mind even if the bolt snaps from the uneven loading, you would only fall or more accurately tilt backwards, until the arms hit their normal stopping point. In theory, stopping this acceleration could cause the stand to get overload and fail, but that is probably only the case if there is another defect in the stand already. I cant imagine the force from stopping this fall is any more than the force you cause when you "bounce" on it to make sure it bites the tree (maybe im the only one who does this idk). Also, while i would never recommend intentionally going over the manufacturers weight limit, (and i imagine LW would not like this info out there) a commercial product like this was probably built to fail at about 2000lbs (5 times rated). As Long as you are Tethered to the tree you should be good.
 
My OG prototype, still kickin.

Like captfrank said it will hold a lot more than it's rated for. With TMA testing I believe it has to hold at least 2 to 3 times the weight rating without failure, but I could be wrong.

I told the same thing to a couple guys about the arms dropping down if the bolt failed. If i had to guess, id bet i could get the band to break before the bolt lol.....We're all tethered to the tree anyway,safe and sound.

I would take that bet.

I was looking at the end of my lone wolf band and the fibers in there are serious. Then they pour the rubber over the woven string for a fiberglass effect and to create the shape of the band. I work in boat building and those fiberglass structures can be far stronger than they look as long as it is undamaged.

That being said i dont think it matters since neither would break unless there was some pretty extreme circumstance haha

agreed
 
Thanks guys. I will try a hex head. Only thing that has me thinking now is if the frame has weakened from drilling the holes.

This is why he got his dirt bike back. Super karma for a helpful man. Thanks, I feel better about this mod.
