I was not satisfied with the purchased oiler, so decided to make it. I used O-rings as seals on each end of the glass reservoir, and Teflon washers as seals on each end of the sight glass tube. This oiler also has a ball check valve, to prevent "blowback" of cylinder gases into the oil. . There is a captive brass "slider" over the oil fill hole, similar to some full-size oilers, better than using a tiny, easy-to-lose screw. The assembled oiler is on the right, including the brass tube that screws into the cylinder.
The muffler and gas tank. The muffler is straight-forward, however the gas tank is not per the drawings. Vic Greenwood provided me with the tip of using the total inside of the cast frame, rather than fabricate the tank from individual brass pieces. A notch was milled around the bottom of the frame, and the brass plate was "JB Welded" in place. I pressure tested the tank, and it has no leaks.
