I bought a Rockwell 34-761 with an older style Unifence on it. I purchased it for 380 and thought it was a pretty good deal considering its a 83-651 3 hp single phase motor and the front rail is 83” long. I have no idea how old it is but im assuming its about as old as I am.
So to get to my question. For some reason the fence will not completely lock in place. There seems to be a 1/32 of an inch tolerance issue that is stopping it from locking in. Right now the fence doesn’t even have the nylon slides becuase they are missing. I have to order the nylon slide assembles to make the fence functionable but I don’t know how they are going to fit if I can’t even lock it in now with nothing between the rail and fence head. This is the first unifence that I have ever worked with so this may even be normal for all I know but this is how far it locks down. I would assume that its designed to continue until it reaches the portion of the cam that is flat, but I don’t know.
Has anyone experience this before? Do I have the wrong rail? Or is this as simple as just replacing the washer that the cam rides on? I wouldn’t imagine that I should have to change anything, the fence should work fine without any modifications.
The rail and its thickness.
The tolerance between the locking lug and the lip of the fence body when the locking lever is engaged.
