Craft Store Time
A quick electric pick gun for under $10. Total time to make is around 15 minutes, using a torch, it'a tiny bit dangerous. They work hilariously effectively. I'm not a huge fan of raking, I'd rather SPP and solve the lock.
I bought mine at Michaels. My wife always has 40% off coupon there, so I walked out the store for $6. I've seen them just about everywhere. The Gun style works exactly the same way. The gun power saw comes with 2 saws which you can convert to pick ends. You'll still be able to swap them without any issue.
Grind or file away
You're going to have to destroy a rake... If you buy one with out a handle, you can get them for about $1.50 Lockpicks.com. I wanted the pick to have a longer shank so I drilled out the rivets and ground down both sides down to the rivet hole. This doesn't have to be pretty, it's going to be imbedded into the old saw holder.
I wasn't able to grab a photo of this part of the process. I used a torch to head up the end of the saw until it's cherry red then pull it out with a pliers. I used leather gloves, some how managed not to burn myself.
Note: I ground the end of the rake into something of a point.
After pulling the saw out, there was just about perfect hole for the pick end to go into. I put a drop of super gel in and then shoved it in there. After the glue dries, you can take a razor blade and trim off the excess. If you don't it's a bit difficult to put the 'end cap?' back on the gun. The whole heating the saw deformed the plastic a bit, but it still works great.
You'll see both kinds in stores, and they're normally under $10. The tips are interchangeable between the two. I do prefer the Bogota profile and I think that it compliments the guns movement better than the snake rake, but I didn't want to sacrifice a more expensive pick. Christina wouldn't appreciate seeing one of her wicked wave rakes on this :)
