Learned about set screws and dogs and half dogs. Craftsman/Palmgren DP vise had a set screw to retain the main screw into the dynamic jaw. Appears the original set screw went missing and a nice work around was a lead plug with normal set screw. Watching some videos on what others did I realized I needed a "set screw with dog". Ordered from Fastenal several variations - and the "correct" version is Full Dog 1/4x20 3/8" overall length. New one is hex key drive, original was slot. I could have bought a longer one and cut down for length and then cut a slot - but I am not set up for that.
Compared below. Never heard of these dogs before - so learned something!
