I sure miss our "Help me fix this" thread from days gone by, nevertheless, here it goes!
7" Wilton that seems to be missing a part on the quick nut (endless nut) that allows the vise to quickly adjust to size, and then clamp tight.
The pencil points to what appears to be an open hole that should have "something" there held in with a clip (according to Wilton this week on the phone). No parts are available.
Pic show it all, but I need to fabricate what might be missing for that hole. Oh yeah, it does work, but often I need to reach underneath it to overcenter the "nut" so it grabs on the acme screw.
PM me if you prefer to connect on the phone if you have one akin to this. Thanks!
