Hi All
I am fairly new to mortice lock picking, i have just managed to open a BS 5 Lever Union lock, but now I am stuck on a BS 5 Lever Chubb lock. The main reason seems to be that on of the levers is actually touching the curtain and I can't move the pick past this without upsetting the previously picked lever from dropping back, is this a common problem our have I just got the wrong type of pick (RB 5 Lever curtain pick)?
