Nice work and pics Reg!
Are those half hitches locked off with a timber hitch you're using on the pieces you're lowering?

Something I noticed about your new LD that I really like is that your ropeman can apparently stand away 90 degrees from the wraps on the bollards!
I assume there's something on the LD he's threading the rope through that allows him to do that?
With my hobbs my ropeman needs to keep the direction of the rope about 10-15 degrees from the lay of the wraps on the capstan or bad things can happen.
I didn't notice that about your new device untils I saw your pics Reg.
Good job!

Grover posted this in another thread i thought i'd post it here as well.
You can see the tensioning process of the LD in this video around 1.29! Great looking device Reg.

Thanks CB, I get it now, each bollard has a fixed vertical shaft on it's outer edge that protrudes a couple inches beyond the OD of each bollard, this allows the rope man a fixed feeding point.
I'd like to see a close up of that shaft and see how well it captures the rope so it can't jump off track on the bollard.

Sounds like you use the hobbs, not sure how much you still use the port-wrap but that only has a shaft at the end to capture the rope. My point is that only once or twice have i ever had a turn flip off and never has it effected it so much as i lost control of a piece. Not sure if that helps you but i know i would be confident that it would capture the rope.
Reg have you tried running the rope in a figure 8 style through the two bollards when lowering big wood? Just curious as to how that would effect the lowering and twist of the rope instead of just going around both bollards. Guess its just other things you can try that no other lowering device has offered in the past. I hope your LD makes it to the US in good time. Really great stuff.

Thanks for pointing it out Jon, although such an obvious facility ought to be expected as part of any conscientious design.

Derrick, the guys have routed the rope all kinds of ways thus far, with the main emphasis being on holding capabilities and fluency. Rope twisting has yet to be brought up so I’ll assume it’s not an issue, or perhaps they just haven’t considered it yet. However, what has become a favourite is taking the first wrap around both barrels for butt-hitching etc….look forward to having a go my self one day. Thanks

It seems like there would always be enough MA, using just the lever, to take all or most of the stretch out of a rigging line. Not having to account for the variable of rope stretch makes rigging a lot easier. How many times has a piece been rigged, accounting for rope stretch [which turns out wrong] and the piece takes a swing/fall and gets snarled? Having a rigging line pre-tensioned makes things flow so much smoother.
