So I had never used a Tramming Tool (let alone heard of one) before and I was on the fence in spending $80 on a tool that might only have 1 application. Turns out… it was money well spent.
I used a T-Square to install my Z mount originally, sort of using the natural bolt travel to install it. It looked like it was dead-nuts, I saw zero light along the edge of the mount and square… I was WRONG.
Well my Tramming tool came yesterday and I quickly found out my Z was tilted clockwise 210 thousands of an inch (apologize I know that is not the correct nomenclature). After adjusting I was able to get my machine to within 17 Thousands of an inch to perfect. (without shimming the router body that is as close as the bolt holes will let me twist it. For what I’m doing that is WAY close enough.
The bit sounds when cutting rock maple is much less “scream’ie” (technical term) 
Let me know if anyone wants to rent my tool, if not no biggie.
Cheers’
