New to impressioning and interested in solving the Brinks R70 lock. Read what I could find about process and technique and tips and tricks.
My first attempt didn't work. I ended up filing each stop down to the lowest bitting without the lock opening. When I started, I would file just a few strokes at the location I thought was an impression. But I wasn't sure if that was too little or too much. Then I thought, perhaps it would be better to use the bitting specification and file an impression location down to the next size pin using a micrometer to measure. I wasn't sure but used the Masterlock bitting specification for sizing. But I'm not sure that the Brinks R70 uses those size pins.
So... a couple questions:
1. Does it make sense to try to use the pin specifications and a micrometer to file down to the next depth?
2. Anyone know what the pin lengths are for the Brinks R70?
Thanks in advance!
