quick connect dog bone for HH

[Oroboros]

How about the amount of material above and below the hole? Is it enough?

 

[TylerHoffman]

Aaron, you could get a couple made and send one or two out to treestuff to get it tested somehow. Then they will send you the piece back broken with paper work of the test results. Might want to email them first to see if its possible for them to do a test on this type of equipment.

I'd fly on it. If you look at this picture:

You can see that the stopper occupies the whole surface. It would take a high amount of leverage on the outside to break the top and bottom straps. Remember the slic pin isn't seeing any weight to leverage those points, it's just holding the hitch cord captive.

I'd prefer it was tool steel but would use the grade 5 without worrying.

Thanks for posting those pics Aaron!

I think the coolest thing about the hitchhiker and the reason I invested in mine is the creativity y'all have with add-ons and upgrades. Seems like a lot can be done to this tool without having to reinvest in pricy upgrades. Though I still run mine stock and am just beginning to get the hang of SRWP.

Thanks for all the feedback. Greatly appreciated! Sooo... who and where can I get someone to make this with the appropriate material, rated, anodized...ect???

Depends where you call home. If you are looking to have a half dozen made to test then I would talk to your friend. You can get 4140HT from; MSC, Grainger, McMaster, Amazon.....your machinist will know where to order it from locally. After that you should look for a small machine shop with a cnc lathe that has the milling attachment. If your buddy is not used to pretreated 4140 let him know to treat it like Stainless Steel. It usally runs between 28-32 on the "C" scale.

The addition of a bone like this on the new HH would probably have me switching to the HH full time. The time savings for me would be substantial.

Monkeylove, great info. I'll file that back, as I too have a machinist friend.

I love it when ML goes all techno-machinist on us. I have a machinist friend who I haven't seen in awhile, but I was always amazed at his memory for the details of it all. Must be a common trait of machinists. The good ones, anyway. I suppose that if you don't pay attention to that stuff, you can damage a lot of very expensive machinery.

 

[JTree]

Or ruin expensive material.

 

[monkeylove]

Lol Jeff. You could screw up the machines but usually it lets you know you are doing something wrong before that happens. Unfortunately even the cutters are not cheap and that is usually the first thing to go. More importantly you know you screwed up and that's just embarrassing to our egos. Kind of like if you guys put a chain on backwards. It would eventually screw the saw up but you would be way more embarrassed by the fact that you screwed up by putting it on backwards.

I can imagine that... like threading a ZigZag onto a 150' rope all the way up to the end with the tight eye only to discover that you threaded it on there upside down? Not that I've ever done that... just sayin'... I've heard that people have done it... read about it or something...

My buddy in Lincoln has a little shop where he works on all kinds of crazy stuff and he has this small mill he machines custom parts he needs for everything from his Harley to a feedhorn on a microwave satellite uplink transmitter. He told me what that little machine cost, once, and although I no longer remember the figure I know that I immediately gave up any idea of ever owning one. It just looks like it would be a blast to have one, though.

 

[MikePowers321]

I like this idea. Can't wait to see what comes of it.

how much would you guys be willing to spend on a dog bone like this?? If you had the option say to buy a HH2 with it would it be worth $20 more??

 

[monkeylove]

Yep, really liked the HH, just hated dealing with the knot everytime. Sold it here just for that reason alone.

I deal with that by leaving the HH on my rope all the time, but I can see the annoyance

 

[pctree]

yup me too, I take mine off the rope every time I need to replace the hitch cord!

 

[monkeylove]

Well between leaving it on or marking the hitch cord (my other post in the hh2 thread) I would buy one again.

Paul, It's hard to put a price on efficiency. You have a great tool that could really benefit from the pin mod in my opinion.

I realize you do a good deal of crane work, and many guys I know feel the HH shines there. With all the different types of tree work/tree workers out there, it's really hard to please everyone. I do A LOT of pruning, and taking the device OFF/ON the climb line is the most reliable means of redirecting. Anything at all that makes for a more user friendly experience will add up. Even if the device doesn't get hung up in a union while redirecting, the tree might not like having a hunk of metal dragging over it under pressure.

I know that my experience differs from everyone else, so it's just my $0.02.

Best of luck.

 

[aaronf]

I'd pay the extra as long as the dog bone is named after me.

 

[pctree]

how bout a compromise , the aarf bone?
