Curt...Those are the tires but mine go to 40 psi and I have 34 in them now. Inside the case at the bottom of mine was a piece of wood. Behind that piece goes a steel plate about the same size and bolted to the wood. Then on the outside is a piece of 90 degree angled steel bolted to the inside piece. Then a 1/2" piece of round steel is welded to the angled piece on the outside and then the wheels go on. Brass bushings on both sides of the wheels. Drill a hole through the end of each side of the axle outside of the wheel and a cotter pin goes through the hole. My Samsonite has a built-in pull-out handle. The pull-out angled bar at 45 degrees is a more complicated matter. It is not necessary but I wanted it so that I could swing out the T-bar from the case and have it rest at an angle so I could pull out the film holders and take the tripod off the top of the case before doing anything else. I will take some photos tomorrow of the fabrication and post them for a better look for you. If you can cut steel and weld it can all be done in a few days. But the best part is the simplicity of the angled piece at the bottom with the axle welded to it and then the wheels just attach by sliding on. I figure the whole thing with cart, camera, holders and tripod weighs about 70-80 pounds...but there are no brackets for the axle. You'll see how it works in the pics. I pull the cart and it really glides along with those inflatable tires. Solid mower type would be a bummer so these tires are great for airing them for the conditions you are working in. Check in on this thread mid-afternoon and I should have what you need.....Here is another shot-different angle...........Tav
