    Next generation snatch block

    Why is that? The ring generally rotates with the traveling end of the rope. That rotation load is spread out over the entire bearing surface of the ID chamfer of the ring. If you use the 'improved' soft shackle design, that bearing surface is also spread out over both legs. I still haven't...

    Rope for DIY soft shackles

    The 'improved' design of soft shackle is pretty easy to tie, but if you don't want to learn shoot me a PM. The important thing to worry about with soft shackles, and Dyneema in general, is D/d ratio. Generally, the larger that ratio, rope dia vs edge radius, the stronger the system will be...

    Pretty easy to wash that stuff every few months. Take care of your gear, your gear takes care of you.

    Next generation snatch block

    My block is rigid to help lower the bearing/bushing load on the soft shackle where it wraps around the ring. If the soft shackle is attached to something with a smaller D/d ratio you can get a higher friction rub area on small radius on the OD edge of the ring. The block takes a fraction of the...

    I gave the rubber band idea a try, no matter how tight and how many rubber bands I used I couldn't get the soft shackle tight enough to prevent the ring from flipping sideways with a very light 'wiggle' test. My block prevents that from happening under even rather violent motion.

    Next generation snatch block

    I finished up the design on my snatch ring 'block' device. This works fantastic to keep the ring from 'tipping' over when the line becomes slack during a vehicle recovery. This keeps the line in the proper position on the ring and prevents you from having the lines saw through each other...

    Synthetic winch line question

    Generally, once you get 10-15 percent of rated load on synthetic line it will permanently remove much of the air space in the braid. This will let you fit a bit more length on the drum vs steel cable typically. As others have mentioned, the closer to the 1st layer the stronger the winch will...

    PullPal vs Deadman Anchor

    Everyone is going to have a different line in the sand for what they are willing or not willing to pack around for extra weight. In my experience, carrying around hundreds of pounds of gear, spare parts, tools, coolers, a kitchen sink, etc, is what leads to a lot of vehicles becoming stuck or...

    PullPal vs Deadman Anchor

    So you're saying it is possible, just not practical for you. For me, carrying a hundreds pounds of recovery gear and ending up with an 8000lb truck just isn't an option for the type of 4 wheeling I do. Use what works for you.

    PullPal vs Deadman Anchor

    You can bury the spare tire, a big rock, one of the seats, etc. There is always a way.

    PullPal vs Deadman Anchor

    For me, it comes down to weight. I like gadgets a lot, but eventually you just have too much stuff.... I love the idea of a pull-pal, the concept is very cool, but they are about 40lbs. For me they fall into the same category as a hi-lift jack also being about a similar weight. Some people...

    Next generation snatch block

    I just built it as a proof of concept. There are lots of ways to make it better moving forward. I paid $50 each for my rings delivered. Why don't you think this is strong enough for vehicle recovery? The forces on the ring are actually pretty isolated and generally just compressive. The...

    Next generation snatch block

    Ummmm, ok. Where are your ideas, concepts, and testing again? The velcro strap does not have any load on it. It only keeps my anti-flip block in place on the soft shackle legs. As I mentioned, I wouldn't mind trying a few different strap alternatives. The velcro is so easy and adjustable I...

    Next generation snatch block

    Here we go, first proof of concept.... The possibility of flipping the line out of the groove is no longer a concern. If your ring ( or traditional block ) is going through more than that during a pull, more power to you. This little device will weigh next to nothing. I am going to try a...
