Externally, the only differences between the crummy stock Imp ram, and the much touted NDZ ram, are the "air channels" that run the length of the sleeve.
But what good is this? Looking at where the air input actually is, it seems more likely that these channels will be gummed up with dow33 and not even pick up that little spritz of air from the solenoid.
So... I got bored and am considering doing this to my imp.
Mill it just a little bit deep. I figure a dremel or drill press might do the trick. I figure the hurricane looking grooves at the top would pick up the spritz of air. After all, you can guess within an 1/16th of an inch where the hole from the noid will actually line up. These grooves assure the air is properly channeled.
Thoughts, critiques, ideas on what would be better used than a drill press or dremel?
