Making D-ring mounts soft shackle friendly

[Camdenst]

I picked up a UCF rear bumper with the Black Friday deals and was curious the best way to round out the d-ring mounts to be a bit more friendly to soft shackles.

Still waiting on my bumper, I found the image on here a while back. My apologies on not giving credit.

A file would work fine just to knock down the sharp edges

Flap disc on the outside. Die grinder with a carbide burr on the inside. The only parts you care about rounding over are where the rope contacts the bumper tab during a pull.

Damn I still need to do this

I used a die grinder

I started with a big step bit, moved to a carbide bit on a die grinder and finished everything smooth with a little 1/2" flap disc sander bit and a 2" roloc.

I just used a simple round file to take the sharp edges off mine and it worked great for soft shackles.

Thanks for the help.

These things are pretty cool:

You will have to report back on how to get the tool in there

Companies that make bumpers and thru-weld steel D-Ring mounts to them should chamfer them for customers now that soft shackles are more popular.

I personally use a standard shackle then put my soft shackle onto it. I don't have to worry about scrapping the side of the soft shackle. I know a couple people who's soft shackle wouldn't fit into their bumper anchor points for one reason or another.

In your usage, what is the purpose of the soft shackle when it is attached to a steel shackle?

So I don't have to take the steel shackle off the bumper or feed a soft shackle through the 3/4" hole in the bumper. It makes the connection and disconnecting go faster.

It's honestly been a while since I've used a point in my bumper that needed a short shackle. The last time a point was used was going over a steep rock face. Then we just hooked the winch of the Jeep behind me up to the steel shackle. This allowed him to ease his winch out as I went over.

It would be nice to not have to carry d rings,(I carry one)they are heavy ,we switched out our winch line to synthetic for a huge weight reduction.im about to just carry soft shackles and a couple of aluminum donut's. what about the mall cruisers that drive around with d rings attached all over the place.

I leave mine attached all the time but I lock them so they won't get stolen:

I think what he's getting at is that the goal is to remove metal from the system, therefore eliminating potential breakage and projectiles. Obviously, we can't remove 100% of the metal because you have to attach to something but a soft shackle and synthetic line creates a safer system without storing kinetic energy like metal shackles or steel cable. By hooking a soft shackle to a steel shackle, you've reintroduced the hazzard.

Correct. The steel shackle is redundant and needless. The primary purposes of the soft shackle are to reduce weight and to minimize connections.

Soft shackles and synthetic line both store energy when stretched. The difference is weight. A simple way to visualize this is you and your buddy each grab 4 feet of winch line. One of you gets synthetic and one gets steel, take turns whipping each other and see who quits first.

Synthetic and steel cable stretch roughly the same per foot, they recoil at roughly the same speed. Due to the kinetic energy formula revolving around mass and velocity, the steel cable delivers a lot more force if it strikes something if both part at the same loads.
