TM glad you found a good deal on a HH. Seriously! As everyone here knows I love getting cheap old shit that is durable and will put in good service. Pretty much every vehicle I own including my crane is 20 years old and runs great. I really don't get to climb enough anymore but when I do it...

Sherrill ripping off the Comm systems was inevitable as I had no legal protection and they have NO ethics, the really disheartening thing was the arb community never even mentioned it. I put years of my life into Ropetek, every free moment I had and introduced a rope ascender at 1/4 the price of...

The material is 4041 steel, very wear resistant but can be drilled conventionally​.

Wow that is an old one. Believe it or not, but I turned that dogbone on a lathe and drilled the holes. Cannot believe the amount of time I used to put in for ropetek, those days are done.

On the rare occasion that I climb I rock my HH1. Im not aware of a difference in performance between the 2. Biggest problem with the HHs is the same as the Wraptor, they don't break and give years of service and in my opinion are very reasonably priced. I should have gone to business school with...

they suck

Shoot, just put one together and the high torque 8-32 screws that I ordered are junk, thread just strips out of them...:X Overnight from Mcmaster will hopefully save the day.

Good idea Bud on sending a check, include your mailing address and it will go out monday

Next week

WOW pricey lil sucker:O

Nick do you have a link to that attachment devise??

My machinist has an EDM for making molds. Laser cutting is pretty impressive too, way faster than water. 3D printing is the way of the future though....

Yes Cory the side plates and the dog bones are cut with water and an abrasive material. Amazing isn't it!!

Burnham, I was hoping to sell the pulley with the HH2 as a package deal and also offer them for sale so the original users could utilize them. However I still haven't been able to come up with a design to my satisfaction so we may have to offer them as a separate item at a latter date

BOTS we are very impressed by the AR400. We have it water jetted like the old ones but with the old ones we would have the bolt holes cut small then size with a drill bit . This stuff you cannt touch with a drill. We were worried about it being brittle but that is a non concern, we have pounded...

No way we could use Stainless. The originals used 4140 pre hardened plate, basically a tool steel, very hard but also costly. I decided to try the AR400 as it is very hard and wear resistant, it works nicely. The interaction of the biner and the slot is hugely abusive to the materials .

No aluminum isn't posible IMO

Merle, before whipping the cordage remove the last inch or so of core, this will make putting it through the eye much easier. To make the hole larger we need to make the DB larger and then consequently the HH bigger.
