Last year I wanted to construct a wood frame style Ruck Sack like the one illustrated in the SAS Survival Handbook by John Wiseman.
The one in the SAS Handbook is called a Fork Frame, I decided to mock up a similar frame known as a Roycraft Pack Frame. I constructed it using Maple branches the thickness of my thumb.

I striped all the bark and knots off the sticks so I won't have anything jabbing me in the back.
I lashed the sticks together with some 550 para-cord. For the ruck I'm using an old canvas bag I use to stow the sail for my Sunfish (sailboat).

I'm using a couple of stones I got outa the stream to help me attach the ruck to the frame.

I tied the stone in the corner of the ruck then tied a slip knot to the frame.

I stripped off some bark from a sapling to use as shoulder straps that I'll attach to the frame.

I attached the shoulder strap to the apex with another slip knot.

Then I just used a square knot to attach the shoulder strap to the base of the frame.

It feels surprisingly comfortable and fits perfectly.

It the perfect size Ruck for a weekend trip.

Thanks for checking out my Improvise Ruck Sack And Frame.
