Will104; Do you have a small "apron type break?, or a 'leaf type break?
Forming most ANY type of lock using a 4' or 8' break, especially the Pittsburgh lock is quite simple.
Please post back with the type of Break you have (if any) and we will give you some further "breaking" instructions.
btw, a leaf or apron type break will work best, a "Bar Folder" will not.
a 'Pan/Box type break will do the job too, if the 'fingers' are closed.
