THT vs. Safebloc vs. Thundersling

can we see a pic of it please John?

A photo won't really show the issue. It just won't come off the sling without assistance from some additional tools. Then it won't go back on the sling without some serious leverage to realign the sides. After one time through that deal, I just left it on a 1/2" loopie. It should be noted that I haven't used a pulley of this type for many years for the exact same reason... the sides only hold up with favorable rope alignment... which doesn't cover much ground. I had high hopes for the AFB, but given the limitations of this type of construction I guess I should have known better. :tarjetaroja:
 
I'm sorry I've been away from the Buzz for about a year now. I'm doing a word search to find any threads that I should/could add any valuable information on. I read this one. Yes, it was due to my xtreme attention to detail (or pickiness, it be called) that delayed the SafeBloc being available to the public. Sherrill would not settle for anything less than the best as well. I am so thankful that Sherrill is wonderful to work with, they let and WANT me to be very involved. The small batch of SafeBlocs that didn't appear to have a great finish, were NOT stripped and redone by the way. I doubt that could even be done, because it's not a true coating, it penetrates down through the aluminum. Anyway, those few safeblocs were put into working use and still being used daily, the hardcoat actually holding up excellent, but just didn't look as black or finished as they should have been. The ones for sale are of excellent quality and appearance. SafeBlocs are in stock and being sold daily. Thank you Merle for giving info on the name, THT was my early name for the prototype. When ready for production a wise gentleman and I were talking about names. I believe he started the topic with talking about picking a name that means more for the product. Tom Hoffmann , (OldFart on the buzz) was that wise gentleman. We brainstormed on names with the topic started by Tom and some good ideas by Tom and by the end of the conversation, we both agreed that SafeBloc would be a great name. Sherrill also loved the name and thought it was better than THT. I asked Tom recently if it was okay that I share his name with the public and he said yes, before this, in talks with groups of people, I just referred to him as an "old gentleman". It is used in the location that a regular arborist block is traditionally used. It adds safety by reducing the forces on the rigging point. It's not quite a block, so leaving off the k from the spelling makes sense to make it a bit different. Anyway, just wanted to add more info to the name thing. I pulled away from all forums and most social media things. The only thing I stayed active with was my instagram account. My instagram account is THEXMANJDD for those that use instagram. I had fallen into instagram to satisfy my social media sharing, due to it being fast and only very short videos allowed, so it limited me and I had time to do it. Now that I've finally logged into treebuzz again, I hope to get back into being more active with treebuzz again. I was on treebuzz just about every evening of my life from 2003 or 2004 when Jerry Beranek told me about it, all the way to spring of 2015. I miss the buzz. Great source of information and sharing. I probably won't get to reading my personal messages on here for a while, it's full and overloaded, sorry for the delay for those that wrote me there.
 
Nice to read you again David. We met at the expo last year. I spotted the THT at sherill's spot and we talked for quite a while about it. I was disappointed that I couldn't get one right there but I was willing to wait. It will be an awesome addition to my rigging gear very soon. I still have FOB banned from my household. They will never have a song played in my presence again for their Tom foolery.
 
So is there more user feedback. I watched Lawrence Shultz video with it recently. It seemed like it had some good application. I guess it takes the place of other devices for bigger weights. How much climber control do you have in the tree? Also most of the other in tree friction devices are not recommended to be used with a basal friction device (RNW AFB) but the safeblock is great with a porty? Just trying to decide if I want to add this to the arsenal. Really don't use blocks anymore. Have transitioned to all rings and the omnibloc as my main as it is so moveable in the tree. I'm usually through rings then the last attachment is the omni. It comes with me all over the canopy until the wood is too big. Once that happens it drops out of the system and I use all rings.
 
So I'm fairly new in aerial friction. At this point the only devices I have besides packing a porta wrap up the tree is a self made rig-n-wrench (works great and I will be buying the real deal) and a rigsaver from treestuff that has a ring on one end of it. My only concern with purchasing the safebloc is, what's the chance of rope on rope when lowering wood? I've found an image online that shows what I'm thinking may be an issue. Anybody notice any problems from this?

I've thought on that as well. The only way I can see it becoming an issue is if everything would push directly to the spar. In that pic the only thing I can see is added friction and heat. Since both lines are moving I don't see a risk of the line severing.
As much as I like my blocks, I'm gonna end up buying a safebloc. Just yesterday I rigged out a large section and had one small limb left till I needed to reconfigure the rigging set up. I could've at least sent it down to the ground while the guys were processing the large piece and then set my redirect for the rest of the tree. Instead I had to wait. Really wouldn't of been a big deal but in my back cut to fell the spar, the skies opened up and I ended up soaked. Those few minutes would've made the difference.

That's a good point. I hadn't necessarily thought of that.

Any body know if it adds additional wear to the rope, even if it doesn't burn itself in half. I know the friction alone will add some wear, as the selling point to blocks and pulleys is reduced friction and less wear on your ropes

In that picture it looks like the rope was threaded backward through the bloc. Just make sure to start the rope from the hole closest to the splice and I don't see how it could load that way. I love the SafeBloc... but can say that I watch the rope run through it. I'll maybe have to watch it on Monday.
 
John, I was just about ready to say the same thing. The rope should have been threaded from spar to the bottom, this keeps the rope from rubbing upon itself. The way it's run in the picture is guaranteed to cause rope on rope wear! If you start from the top lifted toward the spar, feed the rope inward through the top hole, outward through the 2nd hole and inward through the 3rd, if necessary. I hope this helps, be safe and let 'er run!
 
Anyone with a safebloc mind posting a picture of it ran correctly? Maybe before and after a negative block is cut.

In my mind I'm seeing the rope being either close or in contact with itself even if threaded the way that you are saying.

But I haven't ever had one in my hands to know for sure. Just speculating from pics online.
 
I'm not seeing it either. No matter what the middle hole brings it back to the part of the line that is going up. It's probably a minute amount of rope on rope wear.
 
Ya it sure seems like it would rub regardless,if that is the case,I'm going to have to say the picture has it threaded the better way imo
 
I think it all depends on your rope angles. If you are standing directly under your load when you are lowering it then I could see it happening. If your porty is outside the danger zone then I think the chances are less.
