Well I got er done. Now if I can get a picture to load.
I DID get it to load!
I made it larger than the ones in the link because it will be my bench top station.
18" wide X 18" deep, with a 12" top. Sizing 357 max I had to hold it with one hand to steady it so I put my shooting rest sand bag in the back and it is rock solid now. May make further changes but it looks like it will work OK.
