Like the posters above I have mine mounted on my router table, an LS17 System. I also occassionally use it on my tablesaw, although with the Wixey Digital fence that is now not very often.
I have a 14" bandsaw, and couldn't see me mounting an LS17 on that, likewise on my drill press.
What are you trying to achieve with an Incra fence on these 2 machines if you don't mind me asking.
If you gave people a few more details, you may get better replies.
