You’ll have to be a little more specific as to what “leaning slightly to the right” and “the bracket” means…
In my mind, “leaning slightly to the right” means the top of the tool is is kicked further to the right than the bottom.
So, to correct that, you either need to shim the right inside of the top mount bracket, or the left inside of the lower mount bracket, to kick it back in line.
It also could be a combination offset and where you need to shim it may not be directly to one side or the other.
I have the same bit, and with a bit that big, it is usually pretty easy to tell how much further it needs to go to be trammed when you move it close to the spoilboard.
@vicious1 also has a tramming tool here that can help figure it out
For whatever reason, my router was initially pretty badly not trammed initially, so I ended up making a mount based on the above mentioned thread discussion
This worked great for me, but if my router was pretty close to trammed, I probably would have just used the tape.
I maybe could have fixed mine with tape, but was testing the ideas in the thread and wanted to see if it worked. I can’t remember, I think maybe it was @bitingmidge 's idea?
