I purchased a bunch of practice padlocks on ebay. i have picked most of them already, except for a Brinks R70 secure padlock (the type they recommend for storage units). I have not been able to pick this yet. It seems to have a fairly heavy spring tension on the plug that has to be overcome to set the pins.
Any advice out there? Am I on the right track? Is there some type of side bar mechanism like on the Medecos?
Thanks
