The next step in finishing the pack frame…

Here’s a detailed photo of the naked frame with an initial coat of oil & pine-tar coating. This will weatherproof the whole thing and make the rawhide less appealing to critters (I caught my dog licking one of the lashings this morning). This mixture is about 60% boiled linseed oil and 40% Stockholm pine-tar, an ancient coating used on just about everything in pre-industrial northern Europe. It should dry in a day or two and be ready for a second thin coat later in the week.

Wooden Pack Frame

One of many projects happening around here this yule-tide season. A new classic-style rucksack is being sewn, much leatherwork is occurring, and this pack frame is being finished. The wood is shagbark hickory (Carya ovata) made from a bowstave section and some other scrap from the pile. All was split before finishing so the grain is perfectly aligned with the lumber. This made for easy steam bending. As I was working from many examples but no actual plan, there was a lot of mock-up and tweaking of the design to fit my size and intended needs. There’s no metal in the construction. The freight bar and cross members are half-lapped and lashed with rawhide. The bar is also pegged to prevent slipping under load. More to come as it gets finished and field tested.
