Apologies in advance for posting about bicycles, but here goes...

I decided to take some play out of my Shimano Deore pedals.
No problem w/ the dust cap and 8mm nut, but could not figure out any way to move the cone.

It appears completely smooth (round) w/ no flats.
I tried:
o an awl
o various size scredrivers
both on their own and jamming them between the cone and pedal to achieve an interference fit, then rotating the pedal.
o half a hemostat
o extremely long needle-nose pliers, but access hole through pedal did not allow jaws to open far enough to encompass cone

There is not much room to work, so I don't think I can get enough of an angle to place a nail point on it and tap it 'round.

I don't have any small sockets w/ rubber lips...that might work.

Any suggestions?
(my equivalent Suntour pedals on my other bike {yay, Suntour!} adjusted fine.)

Mount pedal spindle in a vise with copper or nylon jaws,
locknut up.
Slack locknut with socket.
Lift up tab washer enough to turn cone with fingertip or
tool. Either adjust or disassemble for cleaning and lubrication.
Oil locknut thread.

Tighten locknut with socket.
Evaluate, repeat until bored.

There are some things machines to better and this is one of
them.
