Gixxer posted that photo a whole back and it got me thinking. The times when I have some problems stamping is when the ricasso is tapered. The stamp won't strike right. I took the plate from my arbor press and ground a slight angle to two of the lobes sticking out on the foot plate. It gives me two slightly different angles to hold the blade so the surface at the stamp is parallel to the stamp. It works perfect.
I have a pneumatic bottle jack (air powered with a foot switch) that I plan on using to create a setup with which I can position the base plate at any angle I need to get the marking surface parallel to the stamp. It will look somewhat like Chris' unit, but instead of a plain block on the ram,the top of the ram will be fitted with a table that can be tilted a little bit to get the necessary alignment. It will be done by making two round cam plates from 1/4" steel, with a 7.5 degree angle on one surface of each. They will bolt on the ram top where the current top is bolted now ( with the angled surfaces together). By rotating the plates, the surface will change its angle anywhere between 15 degrees to flat. At all times the plates will be solid against the ram, so there will be no possibility of the blade shifting.
