Version 4.81 online

[ArtF]

Hi Guys:

  Sorry for the number of updates, dont feel you must download all of them if the changes I report
dont really affect you.

Version 4.81 add rim% control to the cage gears so the disk may be made larger so as not to
leave too little material from edge of pin to outside edge of the disk. Whilel implementing this
at request of users, I noticed the pin disk was bugged for the last 2-3 versions, so this version
corrects that as well.

Thx
Art
