Dismantle the diskettes. We will just need the front part for the writing surface.

Step 3: Cut the pencil in half

Use your knife/cutter to split the pencil in two.

Step 4: Tie the hose to the slates

Tie one end of the hose to the rectangular hole on top of the diskettes. Make two simple knots if you need to.

Step 5: Tie the other end of the hose to the pencil

Tie the other end of the hose to the pencil. You can make a single knot, but do it real tight.

Step 6: Wrap the pencil around the slate

A sharp pencil works best.
You may use the first page as a safety cover, so as to protect what you've written from accidental erasure.
Tie the slate to your bc or belt.

i like to use the flat "construction" pencils. they have fatter tips which are much harder to break,and you can sharpen them with your dive knife(if you carry one) in a pinch. also they have no eraser, so you can double-end them.

You could, instead of tiying the pencile to the hose, just push the end of the pencile into th opening of the hose. and i tearms ofthe accidental erasing that is realy unlikely. mw slate still has a note on it from my 80th dive which has lasted 15 or so dives without comming off. but it may be differet with the disks. thanks for the intructable.
oooooh, I'm going diving this summer, this will come in handy...thanks!

well these things work great in my pool and i made mine out of those old cases for the nintendo games (theyre clear and work great)

Yup, bringing along an extra pencil is a smart thing to do. I tried a mechanical pencil once, (0.5mm lead) very useful but the tip got rusty after some dives. doctorkb: Its a schrade "simple simon" ss1 pocket knife. pretty sharp but a bit risky to handle coz it doesnt have a bolster to protect your fingers.

leevonk -- wax isn't as eraseable as standard pencils, so you'd have to toss the slate once you'd used it. Standard pencils are perfectly visible underwater -- as long as you're not trying to write on something black! :-)

nice knife, too... what is it? I have one similar, a Columbia River Knife & Tool "K.I.S.S."...

wax pencils or crayons might work well too.

whoah neat did you try those fat preschool pencils that write real thick (they would be verry visable) and domt forget an extra pencil or two in case one breaks

Awesome Idea! Out of sheer boredom I'll have to make a set and add it to my dive kit :) Thanks for sharing your ingenuity!
