Rebuilding this atlas of mine has been a steep learning curve but there is light at the end of the tunnel.? The shims that were on the carriage/saddle were 10 thou at the back and 17 thou on the front.? There was a lot of slop so decided to try and eliminate it.? I have ended up with no shims at the back and 12 thou at the front.? this has eliminated the slop down to between 1 and 2 thou both front and back and middle.? What is bothering me is that i have reduced the back by 10 thou and the front by half that amount so have i introduced twist in the saddle / carriage .? Also does the carriage need shims to protect surfaces.
