Pocket Drafting Kit




Introduction: Pocket Drafting Kit

Have you always got a little notebook in your back pocket, like I do?  

Do you wish you had a miniature drafting kit to go with it?  

Of course you do!  Who wouldn't!?  Well, here it is!

Step 1: Materials

xacto knife
cnc cutter and make the cut software
thin cardboard - such as from the side of a kleenex box
thin flat flexible transparent plastic - "wrap rage" packaging works well
craft foam
some type of adhesive:  e.g. spray adhesive, brush on superglue

mtc file attached

note: make sure your cnc machine will work with Make the Cut. As of this writing, Cricut no longer works with it,but there are other machines that do:  (Black Cat Cougar, Boss Kut Gazelle, US Cutter MH/Laser Series)

Step 2: Cut Out the Backing Board

This toolkit is designed to fit inside a pocket notebook that is 3" x 4.5".

Position your chosen cardboard in the cutter and cut out the backing board layer.

I found I could cut the tissue box cardboard with one pass on high pressure with the blade set at deepest level (6).

Step 3: Score the Backing Board

Leave the backing board in the cutter and go over it again lightly (light or low pressure) with the backing board scoring layer.

The scoring lines will help you position the foam inset more accurately when it comes time to glue them on.

Step 4: Cut Out Craft Foam Inset

The craft foam layer will help hold the tools in place on the cardboard backing.

Lay your craft foam on the cutting board.  Cut out the attached pattern.

I found that I could cut a decent result from the craft foam in one or two passes on medium pressure with the blade set at medium (4).

Neaten up any parts that didn't cut cleanly with the x-acto knife.

Step 5: Affix Foam Inset to Backing Board

Go outdoors (or wear a mask).

Depending on your brand of adhesive, it may or may not adhere to the craft foam.  If it doesn't, then you can use brush-on superglue instead.

Lay the craft foam inset upside down on some newspaper or other discardable material.

Gently spray the backside of the craft foam with spray adhesive.  (Or apply the superglue)

Be careful to avoid overspray which might cause the pieces to flip over and get sticky where you don't want them to.

Gently and carefully position the foam inset onto the backing board using the scored guidelines to help you position it accurately.

Allow that to dry completely.

Tweezers can help you avoid getting any glue on your fingers.

Step 6: Cut Out the Tool Parts

cut out a sheet of thin clear wrap rage plastic and place it on the cutting mat.

cut out the tool layer.

Depending on the thickness of the plastic it may take a few passes.   You can test between passes by trying to lift up a corner gently.  

For my particular piece it took 9 passes on maximum pressure with blade at the maximum depth (6)

Leave everything iin the cutter for the next two steps

Step 7: Cut Out the T-square Handle

Leave the plastic in place and cut out the t-square handle.  You can use cardboard or plastic for this one.

Step 8: Add Score Marks

You can optionally add little ruler marks by etching the scoring layer into the tools.  This is optional, but the protractor is probably useless without them.

Go over the tool cut outs once on low pressure using the scoring layer.  

Step 9: Glue Handle Onto T-square

In order for the t-square to glide along the edge of your notebook, it needs some depth added to its handle.

Take the two pieces of t-square handle cut outs and glue them onto your t-square piece.

Step 10: All Done!

Now you can draw some straight lines!

    This is such a cute idea! I don't carry around a little notebook everywhere, but if I do, I will follow your Instructable! Nice job :)

    Neat. I could see this coming in handy because after all these years it is surprising how often I dig out my old drafting tools in order to do a little project planning.

    Now if you really want to impress us and make the kit even better, how about CNCing a compass and architect scale to go along with the rest? ;)

    You read my mind! I have been contemplating how to best make a compass that could be stored in a flat little shape like this. I have some ideas. It will take some experimenting to work those out. Also, a slide rule! And one other tool that is a secret. I will do it soonish I think. :)

    In lieu of a compass you could easily (I assume it'd be easy) cut a circle template. Back in the old days before CAD we almost always used templates instead of compasses. Circle sizes would be limited for sheets this small but it's simpler than a compass, and I suppose you could do 2-3 templates to fit in the kit.

    I never learned to use a slide rule so I will hold out for the architect scale. :)

    General Tools 843/1 Pencil Compass and Scriber has an MSRP of $3.15, is very compact, and will do the trick up to about a 6" radius. Use a golf pencil or an old, short pencil. Apparently, whiny Amazon buyers are having trouble with the new ones. If the adjustment doesn't hold tight, add a small washer. The most basic compass around. Look at the picture at least. For larger circles, you may have to sharpen the pencil assymetrically with a utility knife.

    Search for flat architectural scale rulers, and you'll have 2/3 of the scales you get on the triangular ones. They're only about 6" long. About $8.
