FLAME EATER - NICK


The castings and materials of this vacuum motor comes from Bengs Modellbau in Germany.
Building instructions and materials are good quality, however, a dedicated attention is needed during the machining process of the cylinder,piston and the crank as otherwise there is no chance to get the engine run smoothly.


This type of engine is called flame eater or flame-licker, due to the fact that it operates with the help of  a flame that enters into the cylinder with the  out stroke of the piston. Once the entry of the flame is closed with the help of a sliding valve, hot air get in contact with the air cooled part of the cylinder and causes a sudden drop in pressure that is  sufficient to suck the piston to create the exhaust stage.







Length  ( without burner ) : 170mm
Width :100 mm
Height : 110 mm
Piston diameter : 16mm
Stroke : 26mm


I have made a one piece crank from steel instead of  suggested 4 piece crank from steel and brass and also used double bearings at each side to obtain a better strength against 100 mm flywheels.

      1/15 Scale Wooden Model  


Built from lime wood, teak, plywood, brass and bronze. All brass and bronze parts are machine turned to fit their exact scale.


Frame from 4 mm plywood. Good quality plywood
 is used to obtain a straight keel and frame.
Planking one by one from each side in
order to avoid from twisting of the keel.
Planking completed and the first putty applied
after reaching to the final shape of the boat with
100 grid sanding paper.

The end parts of all open frames were cut as those areas
 are needed for building the interior parts of the boat.

After several layers of putty, and repeated sanding
 process, the first coat of paint applied.



Bottom paint and waterline completed.
