No problem Jon.
Get a piece of M12 threaded bar approximately 650mm lg. Bend around 150mm at 90 degrees to form a handle. On the other end fit 2 M12 nuts and lock them together flush with the end of the bar. The 19mm nuts fit inside the inner fork piston head to hold it still while you undo the allen bolt on the bottom. This is only good on the LTD forks. For the B1 and B2 forks I got a think it was 9/16″ socket. I heated it cherry red and forged it over the top of the fork piston head and used a standard 1/2″ ratchet and extensions to hold the head. On B3 and B4 forks it is different again. I believe a square taper of some form is required.
