Reply to The VCI arcade mod screwed up my jog wheels...

So, after a few weeks of work, I just completed the VCI 100 arcade mod, and the new buttons are absolutely spiffy. Now that I have it put back together though, the scratch function on the jog wheels does not seem to work. Strangely though, when i tip it over a little bit, it works all of a sudden.

Most likely this is due to my having to improvise with the screws as my friend's dog ate the other ones (I'm not kidding), so all the screws in the jog wheels are not the same as the original ones, they are much shorter in fact.

Does anyone know how the jog wheels work, and what things i might tweak to fix it? Also, if someone knows the size/type of screws that the jog wheels take?

Thanks in advance!
