The Bell cylinder puller.

[pcbear]

I have just recently purchased one, any tips appreciated, eg Do you drill a pilot into the keyway 1st? if so where, top or bottom? Or any other tips.
I did a search for a thread on Bell Puller but could not find what i was looking for.

hmm... it's viewed as destructive bypass so isn't discussed in the public forum...

did it not come with instructions of some kind?
