lighweight backpack construction problem - 05/13/12 10:25 PM

I am trying to make the lighweight backpack and I'm stuck. The depth of the back bottom is deeper than the sides are wide. What am I missing? This is the one place where their are no pictures and I'm really confused on the final assembly. Any info would be appreciated.

I'm making it from plans on the the website, the ultrslight pack, g4 by gvp gear is the title on top of the plans. An additional question: after the front, sides, and back are sewn together hoe do you get the waist-belt and shoulder strap bottoms out? Thanks

Are you using just a normal household sewing machine for this? Never thought of making my own backpack.

I have made several of the G-4 packs, one of them modified as well as a much modified 2600 cu. in. RayWay pack, and had relatively little trouble with any of them. I used an inexpensive Singer sewing machine with the zig-zag option to sew them; it worked just fine. You definitely need the zig-zag stitch for the bar tacks. I have read both of your posts and still don't understand the problem you seem to be having. I'm sure I can help if I can figure out your difficulty. What about photos? PM me if I can be of assistance.

Looking at the plans, I think he's talking about how the bottom part of the pack is wider than the upper part. Instructions (step 7) refer to an "angle point" but there isn't a picture to visualize this.

Is this what you are confused about, rowdybob?

Never mind guys, I figured it out. Just FYI I sewed the whole thing by hand, with upholstery thread doubled and backstitched. Very strong. I made it out of durable fabric whuch is a lot heavier but that wasn't my concern. Here in Northern Arizona there are many rocks and the occasional cactus, juniper and cypress trees. So far so good on durability.
