Lockwood c4 Bump Key cut using Pak-A-Punch??

Hi,

This is my first post, so please be gentle.

I'm in Australia & trying to make a bump key for the "Lockwood C4" style lock. this appears to be the most common in Oz.

I was wondering if anyone has experience cutting these using machines. I was thinking of the Pak-a-Punch, due to its low cost..

Thanks in advance,

Do you own one of these locks? If so get yourself some blanks and cut keys until one works. Why are you interested in bumping?
Picking is more effective.
