Looking very good.
It just needs a little bit of wood "bling".
Not a lot to offer in the way of "How To".
To make a handle :
a) Go to a local hardware store and purchase a piece of ideally hardwood dowel of relevant diameter. Cut off a length, then glue or screw on a small block of wood on either end.
b) Have a friend who is a wood turner who has some available off cuts so that he can make this.
Into this with the help of a small piece of cherry scrap for a knob for the other end to allow installation.
The vise needs some wooden jaws.
a) Cut some pieces of 3/4in plywood to relevant size
b) Have a friend who is a wood worker who no longer used a short board of white oak, and has a good amount of walnut to be able to glue together to make nice thick jaws which can be drilled for 3/4in bench dogs.
The 4/4 walnut was ripped down the middle on the table saw.
The first jaw being glued. It does help to have a lot of clamps and a flat granite slab to clamp against.
The second jaw is presently being glued. Once the jaws are glued, then need to be planed or sanded to be flat and parallel.
