Hi guys
I made drip oilers for the cylinder lubrication of my various Hit & Miss engines. The material consists of brass, stainless steel and perspex tubing.
The idea came to me after I got a Musa (Retrol) HM 1 engine.
It has a small oiler for cylinder lubrication.
I took the rough dimensions from it and added a drip chamber.
I used Plexiglas tubing because it is very easy to work with.
Sealing is achieved using two thin NBR O-rings, which were inserted into the two covers.
The drip chamber was mounted together with the lower cover and the connecting tube with the addition of screw lock. The dosing needle was glued into the adjusting nut with Loctide 638.
Some pictures follow.
