I've read that to make a Sheridan non cartridge valve more efficient, you have to drill and plug some holes in the valve and such. What are the exact steps(pictures would be helpful)? could this be done with a Dremel?(I have the drill press attachment)

If this is not easily done at home with out a mill or drill press, who can offer me a sub $40 service?
I believe there is a passage way between the upper and lower tube that needs to be drilled also. Otherwise, just modifying the valve will be pointless. Some of the other more knowledgeable folks on here can tell you more.
