I have and it works great (at least i think). It took a little research fron here and trial and error to figure it out. What i do is:
1. Flip the wire form around so what was the bottom is now the top. You can easily slip the blade on the open loop after paining.
2. I then cut the new bottom (the squareish part) to be able to slip the hook on. This cut is easy to crimp shut. Figuring out where to cut is what took trial and error.
3. Pour, paint, apply skirt, blade, hook, fish.
I haven't had any straighten and i think it works great. I think That Guy Skimpy also has a youtube video of this or something similar. Feel free to let me know if you have any questions.
