Got these new waterproof duffel bags (http://firstgear-usa.com/luggage/torrent-waterproof-duffel-bag-25l-capacity.html) for strapping to the top of my tragkorbs.
The bag's D-rings line-up perfectly with the loops on the tragkorb lid but I can't figure out the best solution for attaching them.
I don't want straps going over the bags since the bags can be opened from the top and i'd want easy access during ride stops.
Not enough room for quick-release clips between the D-rings and lid loops. The bag would bounce around.
Bags should be fairly easy to remove at hotels but can remain attached while camping.
Considered zip ties. Considered lashing straps across the bottom. Ideally each corner would be connected independently .
Ideas?
-
bungee cords?
-
The most secure connection is one between the D-ring and lid loop at each corner separately. But the connection is too short for a bungee or lashing strap.
Maybe a heavy duty velcro cable wrap on each corner? That's less permanent than a zip tie, but not as reliable as ????

I think these ITW Nexus plastic clips were designed to work with the D rings. Or you could get a bunch of those cheap aluminum mini-carabiners that are used for key chains. (Or is this what you meant by the quick release clips? - Sorry)

id put the soft bag on the hard bag with the soft bags 4 mounts facing up...
then i would run a 1" lock strap through all 4 mounts on the hard bags and soft bags with the lock on top the whole mess...
it would be secure and easy to put on and remove as necessary...
24" lock straps... (http://www.amazon.com/gp/product/B0028YAXS0?creativeASIN=B0028YAXS0&linkCode=w01&linkId=OYBOSPHBV2KBGODM&ref_=as_sl_pc_ss_til&tag=shopmotobrick-20)
i went to ace hardware and bought the web and the fittings and made my own... total custom...

I've found these handy. The cord can be removed from the clip to thread through the eyelets, and it can then be adjusted for a tight fit. And the clip and ball make it easy to disconnect.
-
With the soft bag on top of the lid, from the outside edge fit each D ring under the lid loop towards the inside, then connect the soft bag D rings with quick connects or the lock straps Johnny posted.
That's probably what I would try 1st.
-
Great ideas. Thanks!
JO - Don't want to invert the bag 'cause then I can't open it.
Chaos's clips are something that I had only imagined. Will buy some of those tomorrow.
Scott_'s idea seams solid. I'll experiment with that tomorrow.

id still use the straps i posted... putts the soft bag mounts down... thread the strap through the hard bag mounts and the soft bag mounts and lock it on top so its easy to unlock to getts into the bag or to remove to getts into your tragkorb... or not use the soft bag mounts at all... didya think of that...
or you could go hipster with the sbiner... (https://www.google.com/search?q=s-biner&biw=1002&bih=444&source=lnms&tbm=isch&sa=X&ei=6R6dVYmNDM7WoATQrrqoBg&ved=0CAcQ_AUoAg)

Maybe lose the rings completely and talk to an upholsterer or someone else with an industrial sewing machine to attach something else on there. Seems the rings would give too much play to be secure anyway. You could have rod fittings on an aluminum plate sewed in with four corrsponding tube fittings attached to the lid, so all you'd have to do is slide the bag into the rod-and-tube fittings from the front. Then all you'd need to do is have something on front and rear to prevent it from sliding out of position, even just Velcro would work for that.
Or, you could epoxy some stiff material to the inside bottom edges of the bag and attach some kind of latch. There's a latch for everything here -- http://www.protex.com
I hate bungeeing, strapping, carabinering and otherwise dinking with stuff while on the road -- give me a hardware latch any day.

greetings...
bungeeing... strapping... carabinering... zip tying... duct taping... fence wiring... rescue taping... non-flexing cabling... and otherwise dinking is considered discerning by bonafide motobrickers...
anybody can install a proper system... butts a cobbled together system... thats genius...

Maybe I'll bring it to the dealer and have them do it. :hehehe
Played around with it this morning and it seems like a single, non-flexing cable that threads through all eight loops is the way to go. Heading to Lowes soon.
-
After trying options with carabiners and/or straps in different configurations, it became obvious that the most secure connection requires a tight connection between the lid loops and the soft bag's lower loop mounts (bypassing the plastic loops). I'm trying zip ties for now. Combined with a carabiner connecting the soft bag's upper loops with my seat bag (or a bungee to the opposite soft bag) the bag remains fairly stationary on the tragkorb. The bag's content can be accessed easily without adjusting any of those connections.
I'll probably cut the soft bag's lower plastic loops off. Maybe substitute Velcro cable wraps for the zip ties.

How about something like this?

Thanks, DingDong!!
Brad - Anything the creates space between the lid and the soft bag clips doesn't work. The bag just flops around.
-
I was thinking more of resewing where they attached on the bags and then figuring a way to have the mating part attached to the tragkorbs for a tight/solid fit....
A little extra effort to have exactly what you want...
-
I was thinking along the same lines of brad-man -- sew or epoxy in something that better serves the application than d-rings. But I got chewed out because apparently that's un-motobricky and too dealer-noid :dunno
But since the question was posted, I guess it's ok to toss un-motobricky ideas out there anyway.
Since the top of the case on which the bag rests is flat, you could create a solid bottom surface for the bag that will mate with the top surface of the case. One way would be to lay out a couple layers of fiberglass cloth like in the first pic. You wouldn't need more than two layers of cloth to keep it flexible enough to bend to get in the zippered hole, or maybe you'd just want to cut it small enough to get through the hole without bending. You'd maybe want to build up a couple layers where the fittings will attach for strength. Fiberglass is light and strong, so there'd not be too much additional weight. Then you'd just lay the base in the bottom of the bag, drill through the bag to attach some kind of male-female fitting, and water-seal with rubber washers and blue RTV if necessary. A slip hinge would work well there, see pic.
If you point the pin towards the front of the case then you'd just slip it in from the front and the airflow would keep it in place. Velcro flaps sewed or glued to the front of the bag and corresponding velcro strips glued to the front/rear of the case top section would keep it in place. A D-ring on the handle strap at the top would keep the bag's top secured to the side of the bike preventing it from flopping over if the bag isn't full. Or, a single D-ring at the handle attached to the side of the bike might even be enough to prevent forward slip in the fittings and keep the top secured to the side of the bike, you might not even need velcro or anything else. Just detach the top D-ring, slide the bags forward out of the slip hinges and you're done.
Devil's always in the details but the concept is sound.
If the work/cost overhead exceeds what you're willing to expend or it's not motobricky enough or won't work for some reason I didn't see, then fagettaboutit. But at least I gave it some thought, which is what you were asking for when you posted the question.

yawl...
the only un-motobricky thing in the whole world is taking a whack motobrick to a dealer...

Good thinking, Motohobo!
I have a feeling I'll try the zipties and carabiners out for a trip or two, and then fab a quick-connector as you suggest over the winter.
-
Thanks Tim -- good luck. Sorry for being snooty, I've been kind of ragged out lately.

i needs to mount my mobile heater kit to the brick of the corn...
seeking idears... needs to be secure with immediate access...

Is that for the Brickocalypse?

:mbird

wow there are some messed up minds on this site !!!
-
A short bungee diagonally between duffell d-rings. The rings themselves should go under your wide brackets on top of your tragkorb. I'd do the inside ones first, put the d-rings through the tragkorb rings. then attach the bungees to those. cross the bungees and commence tucking the outside d-rings under the tragkorb rings and attaching the bungees.
-
Thanks, all.
I cut off the lower D-rings and connected the bag's fabric loops to the lid brackets with heavy duty zip ties. All "play" needed to be removed from the connection in order for this to work. It's not ideal but it's solid. When the bags are empty they can be folded up and strapped into a small bundle on the lid. The weak link now is the fabric loops on the bags. I'll keep an eye on those.
-
Have you considered that you are overly fixated on mounting the bags "TO" the case lids?
How about turning them sideways with d-rings facing in.
Then use the d-rings and the straps that Johnny reccomended to mount them to the tail section.like soft saddlebags.
The bags will just be resting on top of your side cases. To make it a bit more secure, some industrial velcro between the bags and cases.
Would that work for you?

-
Unfortunately not. Attaching the bags to the lids means I can open the side cases without removing the soft bags.
-
?? Trying to mentally picture what the difference is between my idea and what you have been doing as to how the lid opens.??
Ahh, "Do your lids lift off instead of hinges?".
Ok, "How about a Hybrid of my idea?
With bags sideways as I previously suggested, attach what are (now) the lower d-rings to inside handles of the lid and connect each bags (now) upper d-rings to each other via strap across/under the seat.
Does this seem like it might work?

Sorry, missed the part where you have already cut off the D-rings.
Without that restriction you should be able to fabricate a straight forward attachment for the bag.
