8Man:Great job on Granddad's vise and glad you stuck with it and found Kevin to help you with some parts and advice.
Awesome gesture to offer it back to your Dad and he sounds like a great guy to pass and let you keep it for your future bench.
by the way i noticed your grinder is a Craftsman "block" style grinder and here is a thread that might help you if you have any issues or if you want to restore it too.

please post more pictures of your vise mounted on the bench you build for it and your shop. your Dad and Grand dad might be smiling more than you are and you did a great job.
