Possible new rigging device with rings

[Jehinten]

Would a rigging device created with rigging rings for light weight rigging be needed? I know the thundersling already exist, but in my opinion is to much friction to pull the slack back through. I spliced something up today that I drop tested a 400 lb piece of wood into and was able to lower it safely, I would consider that max weight at this point unless I make changes to the design. The good news is that once you untie the wood the rope can be pulled back single handed. With maybe 5 lbs of resistance.

I will work with this some more and see if it will work for my needs, just wondering if anyone else would have an intrest in this. If I continue to get safe and consistent results I will share pictures of what I've made.

So I have tested it a couple of more times. This is constantly handling that 400 lb piece and can also lower light pieces without changing any friction. The amount of friction is dependent on the weight of the load on the line.

Just for clarification the 400 lb piece was determined by a log weight calculator. The 5 lbs of resistance was an estimation and the "light" piece of wood was simply small enough that I can pick up one hand without straining.

There is no load cell or any other fancy equipment involved in testing this, just trying to make sure I don't mislead anyone with my info. So far it looks like this may have some potential in light duty rigging.

Safebloc works well and rope comes back up very easily

Sounds neato. Got a pic or something? Or will it's secrets be guarded like the socerer's stone?
Rings are great

I haven't tried a safeblock yet. It's on my wish list. Just for comparison, how much weight can a ground person handle with it, without a porta wrap?

I'll post pics after I give it a little bit of use. If it is functional in the real world then I'll pass it on to everyone else. No sense in all of us wasting our time if it doesn't work.

I will however trade the secrets for an akimbo. If anyone is willing...

I haven't done any weight tests so couldn't tell you exact. I have had a groundie hold elm logs that were 10 ft long and 8-10 inches diameter without problem. No shockload or anything but that's still decent weight.
