Hi there,
I recently set about installing the rotary hack on two of my midway 49 way joysticks, using the kit purchased from this site:
http://www.markoates.com/rotary/TechSupport.htmUpon disassembling my joystick, I noticed that on my joysticks, there is no 'upper sleeve' piece on the shafts. There is just the shaft, the lower sleeve, and the e clip. This being the case, when I removed the lower sleeve and installed the rotary hack, there was noticable push pull slop in the joystick shaft. i.e. while playing the joystick may lift up a half inch or so. In my case, the nylon shaft connected to the rotary switch is too short--if it were a bit longer, there would be no push/pull slop in the stick.
Has anyone else encountered this? My joysticks are not new from Happ.. they came off a NFL Blitz machine that had issues with it's 49way circuitry. The owner ended up switching over to 8 way joysticks to cut down on the expense of the repair. I'm considering shaving a bit off the 'upper sleeve' included in the kit and placing it on top of the nylon shaft as a means of getting rid of the slop. I think this should work fine.

P.S. I just picked up a pair of used 49 ways for a friend, and those appear to be missing the 'upper sleeve' as well..
