Tender progress 28.12.18

The tender chassis is now back in the engine shed having its fixtures and fittings replaced.
This is underneath the front end showing the brake shaft and sub frame fitted.

A view from behind the front axle showing the brake cylinder which is attached to the sub frame.

 Back to the front left corner where the steps have been fitted and undercoat painted.

 The front left axle box with cover and horn clip fitted.

 A slightly different arrangement for the left centre axle box.  This is fitted with an oil reservoir instead of a grease nipple.

Another tender milestone 12.12.18

Another tender milestone was achieved today in that the tender chassis was re-wheeled.
Earlier last week it was in the paint stage, here in grey undercoat.

Black gloss being applied.

The painter in action, John looks up just in time for the click of the camera.

The chassis paint job completed.

Getting ready to fit the springs and hangers.

All of the springs are new, here one has been fitted with hangers in place.

 Next a visit to the lifting jacks in the carriage shed.  Here the chassis is seen positioned between the jacks whilst still on the slave bogies.

The wheels are positioned in front of the chassis ready to be placed underneath.  Whilst in the shed the axle boxes and bearings have been placed on the journals.

Going up, the chassis is lifted clear of the slave bogies.

Next the wheels are rolled into position and secured with chocks.

Another view.

The chassis was then lowered onto the wheels.

 Outside the carriage shed en route back to the engine shed for brake rigging etc.

A final view.

A Tender behind, 03rd December 2018

With the engine chassis almost complete, work has turned to the tender chassis.  Here the front face plate has been riveted in place with the countersunk rivet heads ground flush.  The steps have been temporarily fitted to drill holes in the support plates, these will be removed to enable the wheels to be fitted shortly.

The rear buffer beam riveted in place.

Rivet head close up.

The tender wheels with the journals polished up.

The bearings have been white metalled and machined.

The journals have had engineers blue applied to check the contact face of the new bearing.  LM denotes left hand / middle axle.

The bearing is then scraped to leave the centre (blue area) in contact with the wheel journal, whilst the lead in edges are scraped back a few thousands of an inch to provide an oil lead in. 
The lubrication of this type of bearing is by an oil pad taking oil from a reservoir in the bottom of the axle box.  This pad is in contact with the under side of the journal which as it rotates deposits a film of oil on the journal.  The bearing is on the top of the journal so as the journal rotates the oil is forced into the lead in, causing the blue area of the bearing to ride on a cushion of oil.

The axle boxes have had the horn guide faces re- white metalled and machined.

The tender spring hanger pins, nuts, and suspension rubber holders have all been refurbished.  seen here having been painted in dark grey undercoat.
