Met a lady at a Rondy and she had a pack frame she got in an Inuit village in Alaska. Its not PC but she is pretty cool. She wouldnt sell it to save her life, she did how ever let me take pictures and measurements so I could build my own. I chose Oak 1/2 inch and shapped it with rasp and file. Noched all the joints by hand. I did use a little glue to hold it together while I laced and tightened. Sturdy as hell!! Got to get to tandy and get some leather to finish it. Like I said its not PC but ought to serve me well on Treks. First 4 Pics are of hers second 4 are mine.
