yes
I do this all the time to set my carving saws up with 3/8 lo-pro. All I do is take a dremmel with any old grinding wheel and make a groove from the top of that 041 bar down to the oiler/pin hole. I do this on both sides so I can turn it over. That's all I do. It takes about 30 seconds to do and oil flows fine.
try it,
