I wanted to use the original style lockdown bars so i kept an eye out on ebay i found 1 but never found another one until a visit to you guessed it Mark c.  When i asked mark if he had one i told him what for and he said be had something that might interest me and yes he was right (SORRY GEOFF) A small set of pinball legs absolutely perfect so i took them home and started the cabinet.  Just made it up out of MDF used an original Lockdown bar mech to hold the front end just like a real machine.  Once i had the cabinet made i had some new side rails pressed up as i didnt want the button holes.
