SM sells their upgrade parts for the patternmaker's vise, including urethane-lined jaws and a hardware kit to fix the problem with the swivels coming loose. An alternative is round over the outer corners of the wooden faces, line the inners with 1/8" leather, and add a leather safety strap between the jaws.
The other thing that can be done and what I did to keep the bolts from coming loose was to use some semi-permanent loctite at the bolt ends, then snug up so the swivel heads move but with little play. Works perfect.
