I Have also Had a wedge (HENS THE NAME !)
I Love them and want to get another some day . But can tell you any kind of Paper work is not really found for this machine ! I know I been there done that . But I will try and help you in any way I can as I have a Fab shop and build most of my own parts. You can ask around here as Guys know who I am.
Just PM me or hit me here . Do you want a new set up like that ?
