Dredger Engine- Crankweb and Firebox Door

Power is transmitted from the dredger engine to a cog on the crankshaft which is held in place with a crank-web.  It is similar to the crank-webs which secure the flywheel.  Similar, but more complex and more difficult to make.

More finishing required, but the basic shape is done.  Note the 2º wedges securing the bearing housing and the oil tube.

The firebox door is shaped.  Hinge, catch and latch coming soon.  The wooden front support is also seen.

The engine is really taking shape.  I am looking forward to seeing it run.

The weighshaft, supported on its brackets.  It will be pinned with taper pins to the shaft.  Also finished the reversing lever and reversing arm.  The reversing arm has gunmetal bushes.  About 2 x 8 hour days in the workshop to make these bits.  Just as well it is a fun hobby.
