Welcome to the forum. 
Thanks for the post and for sharing. Cool mod for the 1sm! I too have a 1sm and am nearing completion of an adjustable rest for it.
Looks like your design is edge leading. Have you ever caught a blade or worry abut that happening edge leading into the belt?
Also, it looks like your design sharpens on the platen. Do you prefer on platen over sharpening on the open belt?
