Treebolts revisited

[Bruce G]

Just picked up some more 1/2 inch and 3/4 inch conduit. Man the 3/4 just seems big. I know in the grand Scheme of things its small but compared to the 1/2 it’s bulky. The materials are cheap enough I’ll cut one from each and see what I prefer. When I’m happy with it I’ll dip it.
I went from sticks to screw ins to bolts. Each method has its advantages. That being said you can’t beat the bolts. And now that I’m used to the small 1/2 inch hand drill I see the 3/4 as bulky lol. Funny how that works. A few months ago I didn’t think sticks were bulky. Now a 3/4 pipe that’s 7 inches is “more bulky”. @Nutterbuster....waiting on those results bro.

Short story...huge success. I'm currently resting up from paddling a group of yuppies and their gear around, but I'll be posting details tomorrow hopefully.

Really happy with how this came out. I’ll clean it up then dip it. I really like the 3/4. I decided to keep it at just over 6 inches. I can always make one longer if I decide I need the added torque. This will hold up much better than the original.

I've caught the sickness... I was watching this post about the grade 8 hardware and was about ready to get shopping... then I suddenly realized that I could use some leftover fiberglass retaining wall pins...

Now before you call me crazy the pins are 9" long and 0.5" in diameter. I looked up their strength and they are rated for 6400 psi shear loads. They weight 2.1 oz each with some 3m sandstrip tape on them. I put some in a fence post and jumped on them till my feet hurt. They are tough dudes. I plan to preset some trees and climb to height with them soon.

Dang, that's a good idea. I know those things are strong. How much do they cost?
Drilling half inch holes is going to takes some serious elbow grease or a hefty cordless.

Yea i was using a 18v cordless. They were free to me. I have a 5 gal bucket full of them but they arent all that long some are 6"

6" will do the trick too. The 9" would be good on some softer wood trees. Set them deeper. I bought some 8" #8 bolts to put in a cottonwood tree that has some soft spots.

From what I am reading nearly same shear strength as the grade 8/carbon rod in .375

I'm all for innovation, and of you haven't noticed I'm a VTBowlts nut. But...

It can't be stressed enough that while grade 8 bolts are overkill and their various attributes are well understood, the same can't necessarily be said for pultruded cf/fiberglass/unicorn horn/mithril. Test, test, test. Climb at your own risk. Stay hooked up to the tree.BE SAFE!!

Oh, and have fun too. Maybe call your momma...can't hurt.

24 bolts ready to go. First thing I’d like to ask you guys is why not dip the whole bolt. Could always go up in bit size to allow them to go into the tree better. They are so silent where there dipped but the undipped portion is loud when you toutch then together.
They also have that strong plasti dip smell to them. I’m not a scent freak but this could def be a problem. I will try some ozone on them. Can I leave these out or will they rust ?

You can leave them out. Guys have tried plasti dipping the whole bolt. Seems they always end up cutting off the 2.5" that goes into the hole. I don't think it works well.

Be careful. That number seemed like a pretty low rating to me. A grade 8 bolt is rated at around 150,000 psi tensile strength. So I did some poking around and the shear strength is typically 60% of that, so 90,000 psi. That's a huge difference. @ckossuth tried fiberglass and broke a piece. Maybe you can post the pic here Carl?

No good. I weigh 190. All it took was a little bit of a hop on it to shear it.

Yikes... i jumped on a few last night... but if i had saw that pic i probably wouldn't have. It seems you guys @ckossuth @Vtbow have tired it all.

In the end though we are comparing tensile to shear and that is a big difference. I think climbing a tree we are applying a shear load and not tensile (pulling on bolt head). I do agree that the fiberglass pins are not as strong as grade 8s and I think i said 6400psi when i should have said 6400 lb load.

Not to be a know it all but you have to multiply be the area to get the shear strength (150000 psi*0.6*shear_area)=shear strength

For grade 3/8 dia grade 8= 150000*0.6*.11044= 9939lb

As said, safety and testing is probably the answer.

As i mentioned earliwr (somewhere )My idea for cf originally sprung from fiberglass electric fence posts, but having worked with glass a ton, unless it was an s-weave or bidirectional of sorts I knew it wasn't going to work. I'm really happy with the cf ones. Again, as always, test, manage your own risk, and diyer disclaimers are the norm

I know I already asked but I’ll see if anyone else can chime in here. What are the cons of dipping the whole bolt. I tried one and it goes in the tree fine and actually slides less. These things are like wind chimes when you touch the undipped parts together. Just seems like it makes sense to dip the whole bolt. Don’t want to do something that’s not safe. Hoping someone has learned the lesson before I Learn the hard way.

Plastidip already doesn't hold up great. It won't last if the tree is rubbing it. Just my experience. It's definitely quieter to coat the whole bolt. But my cartridge holder keeps them separate. As long as you're moderately careful they don't clink. The VTBowlts are even quieter.

So after trying a few pouches/organizers I decided I like this one the best. It’s an Orca tactical Molle edc utility pouch. I had to sew two of the larger elastic loops down the middle to accommodate 2 extra bolts. I also sewed in a cloth to prevent the 2 sides from touching. The exposed bolts were hitting and this definitely keeps them apart. As you can see my sewing sucks but it gets the job done. I put a zip tie on the zipper at the point that I want it to stop and it is now good enough to hunt with. It’s not perfect but it’s a start. If I am careful pulling the bolts out this thing is dead silent. I will also try the nutterbuster bolt carrier(Allen rifle cartridge holder). Although at first I thought I’d prefer the bolts in the pouch having them right there on the cartridge holder is pretty slick. Really looking forward to trying them this weekend.
Almost forgot. The 3/4 inch conduit is awesome. Dipped it and put some orange tape on it and this thing is sweet.

NICE! I like that drill. One of the ways you can keep your self from accidentally clinking the metal ends on the cartridge holder is to alternate the bolts, this way the bare metal end is surrounded by dipped ends. Probably won't work on the EDC pouch cause of the bolt heads but you could try. The 3/4 conduit does look oversized compared to the original, until you finish and dip it, then it is just a quiet little beast.
