I know this is a year old, but I think it turned out great! Looks like no one answered you on fleabay pricing, but the 3.5" are listed at $250-$500 (asking). I didn't check the "sold" listings.
Thank you for posting those before pics! I can really appreciate the time you take to carefully prep them. It is nice to see that middle step in action!
Excellent use and repurpose of a broken vise!!! I have a Charles Parker with a broken body, but excellent dynamic jaw, spindle, main nut, etc! This could work!
Picked up this Wilton Bullet 101020 3.5" stamped 1/74. Gave it a new lease on life. I picked up the stand the same day, but it wasn't mounted with the vise. Gave it some flair too. Thanks to KMScott for replacement swivel clamps.
