Lone wolf hand climber seat

Another bites the dust. I was using after I removed the bolt because I felt uneasy about the mod. Does this put my unit into the trash category or can it still be used as is with the arm resting on platform.

***! How would that happen after the bolt was already removed.... insane
 
Anyone have one that failed without mods? Have new one I recently ordered, no intentions of doing any mods. They must be safe out of the box, been around for a long time.
 
The platform was designed to sit on. The closer you stand to the end of the platform the more force you induce. Compound that by the RATCHET strap people are putting on maybe we are preloading too much. The videos I saw guys gorilla tighten the strap. Now add a aider on the nose of the platform what kind of force is going on here???
 
So after looking at mine, I noticed the arms bend in towards the center of the platform. I believe the left arm was actually resting on the edge of the platform over the hole rather than where the arm is supposed to rest. I also noticed that when looking at the front of the platform at eye level, the whole thing is warped. I dont trust cast aluminum but I guess I will have to since the only way I can hunt my buck today is with my hawk helium and diy kleims platform. I can already tell its gonna suck carrying in two separate hunks of metal and figuring out where to put my plat form while 1 sticking up the tree.

again a non chamfered hole can do that better get out a magnifier glass and look for cracks. if you find one use a 1/16 inch drill bit to drill it chamfer it and epoxy it. the small hole at the end of the crack will stop it.

What happened to it? Did you buy it new? I have two and there aren't any issues like you're talking about.

Word... good points
 
I googled it but I wont be drilling any more holes in metal. Im going to try my cut helium tonight. My luck, It will probably fold over. Im hoping that some day, it wont feel like a whole new hunting experiment every freakin time I go out ,especially after doing these a few seasons now. I think every time I have hunted this season, while climbing, I thought “forget this, next time Im grabbing the summit titan.”

Is there a difference in the XOP top and a legit Lone Wolf? Does the lonewolf have straight slates and the xop has “squiggly” slates? What does the slates of the lone wolf on opticsplanet look like? I cant find a pic without the foam seat. I want the most rigid top.

I know what you mean lol, this is my first year saddle hunting and I feel like every d**n sit is more of an experiment than a hunt.

my .02 for what its worth.
I am curious about tree size in these failures. One thing I have noticed in my not very long use of the hand climber is the pressure from climbing is not directly applied to the bolt or the rest on smaller trees. The size of the tree directly relates to the amount of "pinch" the belts put on the arms which transfers some amount of side load on the arms. This being the weakest plane for the cast aluminum which is fairly thin already. Cast has almost nill ductility and thus breaks when over stressed rather than deform or bend and give us a warning. This brings me to my thoughts on the failure after removing the bolt. Once material was removed (drilling the bolt hole) the strength lost was actually replaced by putting the bolt in the hole. It slugged the hole basically and became a nill factor from a compressive stand point. While the leverage factor still remained. Once he removed the bolt the hole then tried to elongate with the same pressures the bolt was helping mitigate and thus failed due to the low ductility of the cast. My thoughts are, the contributing factor the bolt presents is the leverage from the longer contact point not the presence of the round hole. Chamfering the hole helps to eliminate stress risers from the square edges left when drilling very good point previously made. When I did my bolt mod I deliberately added washers to the allen head to help in distributing the load on the cast material.

If you notice, the hand climber is the only climbing stand component in the entire lone wolf/XOP line up that does not have a brace supporting the arms and keeping them locked together laterally thus eliminating the side loading of the cast components. The reason( in my mind) was that it was not needed originally is exactly the point previously mentioned. The stand cast "Platform' is made short for more than one reason.

1. It was built small and compact for weight reduction. (Thus the draw from us saddle hunters)

2. It was originally intended to be a seat for you butt not your feet and definitely not edge pressure. Not many people would be sitting on the edge as we do by standing on it.

3. By keeping the platform short you decrease the ability to or likelihood of increasing the leverage applied to the attachment bolts.

I think I'm want to put some time into possibly coming up with a removable side bar to keep the arms evenly spaced while climbing. I really don't think the failures have due to over loading in the vertical plane I think the key factor here is likely the belt pinch.

Sorry so wordy but the coffee just kicked in and the fingers and thoughts just started flowing.


Again its just my thoughts hopefully one of the OG Gurus can chime in or this will help get somebody smarter then me's wheels turning.

All good points, makes sense. It's funny that you bring up the crossbar. I once told a guy that owned the climber combo to hook his buddy up with the Hand climber (top piece) and keep the platform for himself. I told him he could cut the cast back flush to the arms to lighten and shrink it up a little. Probably would work good for the people who want more strength etc...

Thanks

I have an old sit n climb I was trying to modify to be a slightly wider version of the hand climber and it has the cross bar. Maybe I will revist that project as well.
 
Im planning on replacing my xop with a true lone wolf HC top. Has anyone directly compared the quality of the 2?

Watching a week ago I Ordered the LWHC from optical plant I haven’t been able to try it out yet wasn’t going to do the bolt mod. Use it the way it’s but now I don’t know it is rated for 300 pounds without mods
