Moving the capstans back by that much would raise the BW by about 4 g and increase friction a tad. Get someone who is adept with action geometry and start your learning process. Don't jump right in blind unless you have hours and hours to burn with the prospects of having to re-do alterations. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
