I acquired an old Star Works Crab padlock made out of brass that did not have a key.
After a bit of fiddling I decided to check my old keys to see if any could be modified to work in this lock.
I have some old CHENEY made in England Pat #481800 keys and with some filing was able to get a key that works in this padlock.
Photo shows the lock open. Key on the left is an original and the key attached to the lock with string is the modified key that works.
Hope someone else mat find this useful.
