I've always loved the effects of the stripper deck, but it costs so much more than a standard deck for a few cuts here and there. I was recently given a deck from a friend who never used it and I thought "Hey, a spare deck which isn't particularly good (it's cheapo). Lets turn it into something." And huzzah: my Homemade Stripper Deck!
Step 1: Materials
Step 2: Cutting the Cards
Position the card along a line. Lay the ruler so that the top is at most 1mm wide and the bottom of the card does not show past the ruler edge (see pic 2). Cut carefully, ensuring that the card stays perfectly still. Repeat on the other side. Personally, when I do the other side (in my case the right for I'm left handed), I actually use my right hand to cut. It feels wierd but it works.
Step 3: Testing
After EVERY card you cut, you must test to see it works. Place it in the same position as the rest of the deck, and stroke. None of the cards should come up. Turn the one you just made over and when you stroke it, only IT should come up. If it fails these tests, see step Troubleshooting. Every now and then, give the cards a cut or shuffle and stroke again. Sometimes, cards are actually not cut far enough, but become stuck so they don't appear to come up.
Step 4: The Hard Part
Note the next picture - the corners are not perfectly round because you've just cut it.
Note the 3rd picture - the bottoms are NOT ALTERED AT ALL. This is essential.
When making these, it is actually ok to take too much off as long as you DO NOT cut the bottom in any way.
Step 5: Troubleshooting
Answer 1: Cut more off. Ensure you do not cut the bottom at all.
Problem 2: The card does not come up when upside-down.
Answer 2: You probably cut off a bit off the bottom. Hard luck. Get a new card or shave off more of every single other card.
Problem 3: You cut off too little and are trying to cut of more, but all that are chopped off are a few bits of dust.
Answer 3: If nothing is coming off, cut off more than you need, but as little as you can. As I said earlier, it is better too chop off too much than to chop of bits of the bottom corner.
Below: Model card. Cut at the top, untouched at the bottom.
Step 6: Perfection
Tip 1: Try to make the way you cut all the cards the same as possible. The image below comes from the card that was used to demonstrate earlier. The left cut gave a spiral shaving whilst the right gave a straight one. This means that the left has slightly less chopped off than the right. If this can be maintained throughout the entire deck (which is hard) you get a very nice stripper deck.
Tip 2: Fairly obvious. Cut off as little as possible to make the card as normal as possible.
Tip 3: I emphasize: DON'T CUT ANY OFF THE BOTTOM!
Step 7: Congratulations
