Cylinder looking down the bore to the piston head. As everything is newly machined, everything has been coated with cylinder oil to help bed everything in.

 

 

 

 

New blower ring ready to fit on the bottom of the new chimney. The small holes are for the blower used to control the draw on the fire. The larger hole are for the exhaust steam from the vacuum ejector.

 

 

 

An unusual view of the smoke box arrangement before the chimney, blower ring and chimney bell is fitted. This shows the complete regulator to cylinder steam pipe layout with the pipe work into and out of the super heater header. Also in view is the regulator valve and the end of the regulator rod as the cover plate has yet to be installed.

 

 

The next three photos show the almost complete drivers side motion with connecting rod being set up to carry out the bump test. This is to check how much clearance there is at each end of the stroke between the piston head face and the covers. The slide bars are marked with a centre punch at each end the cross head travel, the connection rod is then taken down and the extra travel of the cross head past the centre dot shows the clearance at each end. Adjustments can then be made.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cab fittings almost complete, copper pipe work is annealed prior to fitting  to reduce the possibility of cracking in the future, then polished.

 

 

 

 

Brake adjustment turnbuckles, 4 new lock nuts have been made, 2 off with a left hand thread and 2 off with a normal right hand thread. These lock the turnbuckle and hold a captive sliding key in place. All part of the railway belt and braces approach to engineering design.

 

 

 

The new iron chimney casting, fresh from the foundry, awaiting machining for the mounting bolts and the attachment holes for the blower ring.The recess for the fitment of the spun copper chimney cap is shown.
