Can anyone tell me if the Timing Shims from the other guys work on Ultrasabers and also how they work to line things up?
If you are talking about TCSS (we can tell about them here) then yes they work. Although I'm not sure why you would need them on an US because they come already lined up.
As for how they work, in theory if something didn't line up you can use one or more between MHS parts. The pieces well not rotate as many times as without them (they are covering up threads). But that doesn't mean that it will be the right thickness to line it up perfectly.
