CRS
I started cleaning up my #25 and
the more i saw, the more I am convinced that someone working at the Eire Tool Works pulled this puppy out of the scrap bin.
In addition to the casting defects I showed in my original post, there are just so many areas of excess surface porosity to have made it past the inspection dept..... even on Monday morning

As you can see in the attached pics there is a lot of porosity on those pretty curved screw covers, (pic 1), and on the movable jaw (pic 2), and there is a piece of flash in a corner that prevented the movable jaw from closing against the fixed jaw... and just look at the surface finish

(pic 3).
I did clean it up and throw a coat of paint on it to see if it would be worth spending any more time on it and as you can see, in spite of it's questionable heritage, it's still a cute little vise. (pic 4)
If I get some spare time, I may even try to remove the handle and polish the head of the lead screw.
By the way, anyone have any good tricks for highlighting the lettering on castings..... besides spending an hour or so with a tiny artist's brush?
