This is definitely a project worth taking on. I saw one with a wool top on clearance at Pendleton for $295. The wood and hardware were EXACTLY THE SAME! Elsewhere these stools fetch top dollar. If you want to upgrade the leg pivot hardware Lee-Valley has a high end version for $40. Check it out HERE. You could even use handles from shovels as a cheap alternative, too. Of course, if you have some lathe skills you can turn your own legs. Oh, and one last note you may want to know: how much does this little stool hold? Well, I'm a husky 1st Sgt and guessing I'm about 230 lbs, it holds my weight comfortably.
In Company D, we're all about sharing information, so if you have any questions about making these, let us know. Remember, the most authentic seat for a soldier will always be the seat of his or her pants.
