Increase pack volume

[RedundantRigger 0]

Is there a way to safely increase the pack volume of the canopy in d-bag in such a way, that it will fill out a slightly too large container.

Are there maybe d-bags that are constructed extra bulky?
Was thinking of maybe modyfing the one I have, but not sure what to do with it yet...

any ideas?

I have sometimes wondered about tacking or sewing a couple pieces of foam, wrapped in fabric, into a d-bag, top or sides. Never actually tried it.

I have tacked or sewn stiff foam (enclosed by fabric) into main containers, either against the backpad or reserve wall, to change the pack volume. Depending on the design, the foam is semi-permanent or can be slipped out to change the pack volume. My personal rig easily handles everything from a 75 (no crossbracing) to a 170. I get the impression that doing such things was uncommon years ago and extremely rare nowadays. And I wasn't worried about the FAA's rules.

Years ago I had a container that was built for a Raven III and by the time I got rid of it I had a much smaller canopy in it. We did exactly what you mentioned - tacked a slice of foam padding in the bottom of the pack tray. Not sure if it was legal but it worked just fine.

Of course that kind of stuff wasn't dangerous back then.

You didn't "modify" the container... some tacking just happened to be temporarily threaded between the existing fibres of the pack's nylon.

Modifying the container seems a bit questionable. It's impractical because I need the volume for when i put in my large crw canopy. And also, I can only imagine the look on the DZ chieftans face when he discovers a piece of styrofoam camping pad handtacked inside my container

The mod has to be done on the d-bag.
I've seen stiffeners sewn to d-bags to aid a main spring PC deployment. I think a lair of styrofoam and a covering lair of fabric would suffice. I would do this only on one of the long sides, just like the stiffeners.

thoughts?

Have you considered modifying the main closing loop anchor point?
My container was originally built for a 190 main and had a short closing loop attached to the inner top flap.
When I sewed in a Javelin style main loop anchor strap, I gained another 3 inches of slack in my closing loop.
Now the same container safely holds a 150 or 135 sized main, while still maintains decent tension on the curved closing pin.

Just get a brand-new jumper/packer to pack it for you.

Whether sewing in bulk to the container or d-bag, be real careful to not add snag point where lines could get caught under a corner. Even a minor snag that would not last very long before un-snagging could cause a mal.

what if you put pile in the main container, then have your pad backed with hook?

My rigg is infact a javelin. For insight it is the j1kl container size, which I think means that it has a wider main container than the j1ks.

The line/flap snag issue is a concern. Design needs to be simple, smooth and robust.

To reduce snag risk, hand-sew the pillow into the main pack tray.
