Do you have a trigger before the flip-flop???

Hello Gang,

I've got a crystal (7.155 mhz) that I need to use at half frequency. I
decided to pump it into a flip flop, but I'm having an awful time using
2n3904 transistors. The triggering seems to be a very challenging design
issue.

Anybody have any thoughts, (or other ideas for halving frequency)?
