Hi; I have some small machine shop equipment and would like to make some parts. The Flybar in question for my shuttle 30 and my 60 X-Cell . The shuttle flybar measures at .1179" dia. which is supposed to be 3mm. So I ordered a 3 foot bar of 3mm . When it came I tried to put the flybar bearing on and it was too small (the bearing) so I measured the new bar and found the measurment to be .1181 " dia. Which is what the 3mm is supposed to be in our measurment system. Now what is going on here???? Where does Shuttle and X-Cell get their supplies??. Bob
