I think I'm about figured out.
I made up 4 extra compression straps to fit to the sides of the frame. I tried it out yesterday on a 5 miler with a 50lb sack of dogfood, plus 3l bladder & it carried perfectly.
I'm still on the fence about strapping all the individual stuff bags directly to the frame versus finding a large sack to hold everything.
Do you have any updates on this project? I just found this thread, and it is almost exactly what I am planning for this fall! My brother and I are going on our first Elk hunt in southern CO...we have regualr hiking backpacks, but needed a pack frame to help with the loads of camp and meat.
I picked up two Cabelas Alaskan frames before Christmas for $60 each and free shipping...must've been that last they had because the next day I noticed they were sold out. My plan was to strap our backpacks to the top part frame, and have camp stuff and food underneath the pack in separate sacks. Then drop the frame and stuff at camp and use the backpacks for day hunts. I realize its an extra trip to get the pack frames if needed for meat, but the backpacks will be much easier to use during the days in the terrain we will be in.
Our frames have no attachment points on them, just the tubes...so I'm going to make dual adjust buckle compression straps with loops on the ends to wrap around the frame...I see that was mentioned in this thread somewhere. I tested this on a scrap piece yesterday and it works great. For the loop ends, I found that an open loop (where the tag end is rotated 90° onto the the main strap) is better at wrapping around the tube than the flat loop in the picture here. I'll get pics of the open-loop strap I made.
I've ordered 5 ITW dual release buckles for each frame, and will likely order the Wilderness HandiPack or make a similar load panel for helping to compress and hold the separate bags all in place, plus help with meat hauling.
I've been leaning to sew the past couple weeks. Quality goes up with each iteration. These are bags from the Ripstop by the Roll $10 kit, and I made a pack cover from their MTN 1.1 fabric as well. Worked on flet-felled seams on each bag, because I need to make some tarps and a tipi yet too.
Would love to see updated pics of your setup.
Thanks,
MT
