Zero clearance Auxiliary fence

[Alder]

I recently came across A video featuring the late Ron Fox where he had a Zero clearance auxiliary fence on his router table. On this occasion it was for use with a Drawer Corner Lock bit.
It seems a sensible idea but i have yet to see it mentioned elsewhere.
Does any member have experience of using a zero clearance fence especially with fairly small router bits or more correctly where the timber being passed through is small?
Thank you,
Russell

Using a zero clearance temporary fence is very common, I have them for each bit i use regularly. Only problem is if you tend to use a lot of different bits you end up with a lot of them taking up space. Most people I expect make one each time they use a less common bit and then chuck 'em

Thank you for the reply.
What thickness auxiliary fence will suffice? i was considering using 11mm MDF.

I tend to use 18mm MDF, but then that is what I have most abundantly to hand in the wksp. Your 11mm will be fine
