There was a good thread awhile back about this. HERE Keep in mind that the hinge is squared to the fence so the fence doesnt need to me "perfectly" positioned. You can simply drill some extra 20mm holes to mount the fence. I used anchor dogs by UJK back when but I really like the new TSO power lock dogs but they are limited on clamping thickness so that needs to be taken in to account. I will say I do not like the looks of those aluminum plates odd the back because of deflection issues.
I found that thread after I posted, thank you. I like the idea of the undermount dogs that
@Bugsysiegals ended up getting to work. It is interesting though that the particular INCRA track they use does not simply use the standard 1/4-20 T-track slots on the bottom, as his M6 bolt picture would indicate a smaller track groove on the bottom. I have reached out to INCRA to see if they can speak to the dimensions.
How would I attach a fence with the Powerlock dogs from TSO? Those seem great for locking the dog down from above, or joining work pieces, but not sure how to use them to hold the fence on.
I also agree that ideally, I would be able to square the fence, so that I don't ever have to worry about moving the track relative to the kerf cut across my bench. I think drilling some holes special for the fence might be a fine solution, if I don't want to give up much space on the top using the regular holes.
