Hey Stu that Mallet looks first class. But in the third picture of the glue up I spotted something else that is even a better idea. That plastic handled push paddle. When I got mine for my jointer I thought mmmm these are a little on the risky side. When Larry stopped over and we were in the shop he said to put a tail on them. Now I see your idea and voila its just what the doctor ordered. Would you post a clearer pick for us to see. Man you have some great ideas. But I also like how you are open to rethinking your own.
Like Arts suggestion re the vice. Hey when I saw how much space your vice back board was going to take up I thought wow and you worried about space at the back of the vice.
This is one of my biggest weaknesses I latch on to an idea and then get like bulldog and wont let go despite knowing better.
I am getting better though after time on this forum and seeing guys like you alter course. One thing you sure aint going to miss a chisel with that mallet head. It seems huge in the picture.
