Many people have said they use their workbench vise as a pen press, so I thought that is what I would use too, since I have a really great workbench. It has round bench dogs. I just used some scrap pieces of wood against two bench dogs and turned the screw while holding the pieces to be pressed. Well this was pretty awkward because I need to get the pen positioned perfectly centered on the dogs or the dog will twist in the hole and the whole thing slips out.
I have looked all over and can't seem to find any body else that has this problem and therefore no solution, so I decided to make me some custome jaws for by workbench. This is what I came up with. What do you think?
I have no ideas as to why these come in upside down!!!! They are not this way in file explorer. Oh well, maybe you can stand on you head to see them or turn you monitor upside down.
