I will use this nylon bracket I got at the local hardware store to mount the optic board to the shaft housing.  Those that have purchased a later model 'HotRod' version OSCAR will recognize this bracket.  The legs are 1 1/2" long with slots for adjustment.  I used a 3/16" bit to drill a hole through the bottom of the housing to attach the bracket.

The optic board was made by following the instructions found on Andy Warne's Opti-Pac+ website (www.spaceinvaders.uk.com).  The optical switches I used were Optek model # OPB660T that I got from Newark Electronics (Newark # 08F2626) for $1.94 each.  The wafer board is a Radio Shack # 276-147.  Score the wafer board to size with a razor knife and give it a 'snap'.  It makes a pretty clean break.

The optic board is attached to the nylon bracket and positioned to "read" the encoder wheel.  I used a #4-40 machine screw w/ lock washer & nut to hold the wafer board to the bracket.

Here the steering wheel is attached to my I-PAC/Opti-Pac+ test board.  Notice the rat's nest of cables behind my servers.  ;)  Anyway, the steering wheel works great!  My next project (spare time permitting...) will be to mount this steering wheel and my trigger joystick in a new control panel for my MAME cabinet.
