I needed a grab-and-go tool pouch for those times when it makes the most sense to take the tool to the project. My biggest rolling tool box likely weighs in at over 1000 lbs, even my smaller tool boxes are pretty heavy to lug around. I've tried tool belts and things fall out of them, they just don't fit the way I use and store tools. I needed a way to carry my favorite hand tools, without them falling out. This is what I came up with.

What this Instructable Covers

This write-up has measured drawings, and photos that can be used to create cut patterns. It goes over the assembly steps, has some tips about sewing heavy materials. The drawings cover all the main pieces, but there are a couple of straps and dividers that really depend on how you want to use it. It is a like a recipe that says 'season to taste'.

Tools

The big tool is the vintage Singer walking foot sewing machine. It does one thing: sew forward in a straight line. It does it really well. Listed tools are what I used, this project can definitely be done with way less toolage.

Straight edges: Starrett inch-metric rule from a combination square, stainless rule, steel yardsick
Marking: 9mm mechanical pencil (seriously- get a 9mm), Starrett dividers, HF dividers
Cutting: Swann-Morton scalpel, Fiskars forged embroidery scissors, Fiskars forged 12" scissors
Finishing: lambswool applicators, 1" HF chip brush, clean rags

Supplies

Fiebing mahogany dye
Fiebing acrylic resoline
Button post studs
Rivets
Chicago screws
Steel ring

Step 1: Cut It Out

These drawings are designed to be printed as patterns. To get the right size in Inkscape create a document that uses units of millimeters, and set the drawing size to 609mm x 312mm. Open the photo and crop to the edges of the piece of plywood shown. Scale your cropped drawing and it should fit right into the 609mm x 312mm workspace. Now you can print it, or take measurements as needed.

If scaling drawings isn't your thing, there is also a measured drawing of the main pieces. The little tabs and belts aren't showing. My recommendation would be to build this without the belts, put whatever you plan to carry in the pouch, then size the belts to fit your application.

The main box is thick leather, I don't recall what weight. I sketched the drawing in pencil, used a scalpel with a straightedge to start the cut, then finished off with sharp heavy duty scissors.

Step 2: Sew the Front Pocket to the Middle Pocket

Mark out a consistent offset with the dividers, then sew both sides. The bottom edge wants to pooch up, so get a consistent bend on both sides, and sew from the middle to the edges. Snip a 45-degree cut on the corner to help take up the slack.

Put rivets in the corners. I forgot to do this, and it is a pain to set the rivets after the fact.

Step 3: Sew Both Pockets to the Main Box

Same procedure as the smaller pocket.

Again with the rivets, don't forget like I did.

Now is a good time to sew the strap for the metal ring on the back side, and sew any dividers for tools into the top part of the main box.

Step 4: Rivet the Box Together

If you make this out of canvas, the box can be turned inside out and sewn together. I like doing thing the hard way, so this is riveted.

To get a good crisp edge I wet the leather, then bent it in half in a big wood vise. You could do the same thing with a board and c-clamps, or just work the wet leather over the corner of your bench by hand.

Cut a piece of hardwood scrap to fit inside the box. Clamp the backing board in a vise, and fit the tabs from the main box under the sides. Drill or punch a hole for whatever rivets you decide to use.

This is easier with Chicago screws, you can drill without trying to use a leather punch supported deep inside the box. And you don't have to have a backing board for hammering rivets. But like I said, I do it the hard way so learn from my folly.

Step 5: Fit Straps to the Pouch

Load it up with tools, pull tight, and lightly mark where the straps and retainers belong. Trim any lopsided pieces. At this point the leather work is finished.
