Just a heads up, they make for really uncomfortable picks if you get anything but the really thick wiper inserts. Here's what I use to make my picks.
It was about $10 at Lowe's and I could walk you through making picks if you'd like. Here is my handiwork (top). If you don't have a dremel and grinding bit, be prepared for tons of uncomfortable hand filing.
Go to harbor freight and buy their cheap (~$15 on sale) dremel knockoff.
We use that to trim our greyhound's nails and it does a great job. I first use a coarse sanding disc to knock the majority of the growth down. Then I round the nail over with a finer stone bit (http://www.amazon.com/Dremel-932-Aluminium-Oxide-Grinding/dp/B00004UDIT/) to make the nails neat and tidy.
With my wife holding the unsure greyhound in place, I can do all the nails in about 8 minutes now that I know what I'm doing. I very rarely nick the quick, and there's never any blood. The greyhound seems to tolerate it very well.
Hi, I used the 932 tip, and no, I dont have a bench grinder.
I sort of "learned" by this http://www.h-i-r.net/2008/07/make-your-own-lock-picks-part-1.html
Bit like this... cheap, last FOREVER (only on second one)

Yeah, I'm trying to save money on it too. What padlock brand/model are you disassembling? Field stripping this Kwikset is the first thing I did when I got it. Very nice to gain that familiarity with the workings before attacking it.
I went about making the picks by printing a Romstar template, matching scale to the ruler in inches on the print-out. Cut out the desired tools and glued them each to a ~5" long section of feeler stock (1/2" wide x 0.02" thick, meant for testing tolerances in machine shops and production lines. 0.02-0.025" is supposed to be the thickness for North American keyways.)
After glue drying, I clamped the feeler stock in a horizontal position in this small vice, and then used EZ Lock Metal Cut-off wheels @~30k RPM to generate a rough shape (Cat#EZ456, should be able to find for $2 per wheel or less, or even cheaper off-brand products). The slower you go and the less you remove at a time, the longer your wheel will last and the less likely you are to overheat the steel (which can cause weaknesses). I used long, light strokes down the whole 5" of feeler for every pass, removing sub-millimeter quantities each time.
I left about 0.5mm of the white paper surrounding the printed tool template, so that I could more cautiously produce the final tool shape with an aluminum oxide grinding wheel (Dremel 952,932,etc). I clamped the Dremel 4300 down to the counter with the bit hanging over the sink, and then hand-held the tool while using the length of the grinding wheel to remove some of the mountains and valley produced by the very thin metal cutting wheel. Holding the pick while leaving the Dremel clamped made it easy to affect how much metal was being removed with small changes in force applied. I used the corners of the grinding wheel to remove away the final material around the snake/hook/half-diamond business end. The same wheel was then used to remove rough spots and round out the edges.
Finishing used some 240 grit sand paper and then a felt buffing wheel with abrasive compound. All these Dremel items came in this Dremel 4300 kit I was gifted a while back. I have a feeling a bench grinder will do a much faster, cleaner job -- but we've all got to start somewhere! :-D
Edit: I'm in the same situation with the recording. Still have to get my white belt yet though! :-D I'll have to figure out a good spot for my phone, or maybe use my webcam. I agree on the cam, never hurts to have a cheap Logitech cam around.
