7820 Dinmore Manor - The Blog

This blog will follow the heavy overhaul of 7820 through to its return to steam. The chassis is being overhauled at Tyseley Locomotive Works whilst the boiler is being overhauled at Ian Riley's workshops.
We are working hard every weekend to bring together the hundreds of small pieces that require refurbishing to get the loco back into working order. Follow us to keep up todate with the weekly progress and who knows if you like the look of what you see you may even be tempted to join us and help put 7820 back in action.

                                                   TENDER WORKING PARTY


                                         Work has continued on machining the large quantity
                                         of bushes required for the brake rigging. Work was                                       
                                         undertaken on the journals of the brake weighbar
                                        shaft to remove the heavily pitted sleeves which can
                                        be seen after removal. New sleeves will now be
                                        machined and heat shrunk onto the journals and the
                                              support bearing will be machined to suit.

                                                     TENDER WORKING PARTY


                                          In the great Gloucestershire outback, we continue
                                          to hone our bush craft on the tender brake rigging



The new pin has been drilled for the securing split pin
 and the bracket has been re-bushed and this brake
 hanger bracket is ready for cleaning and painting
 
 
With the six brackets well on their way to completion,
attention turns to the next item, the brake hangers.
One is set up for machining to shell out the old top
bush prior to replacement 
 
 
The boring bar being set to machine the old bush
as concentric as possible to the original bore
in the bracket before chiselling out the remains of the bush

 
The top end of the hanger bracket with the bush removed

 

 
 
 
The hanger bracket is 3" wide but had been bushed
from both sides with half bushes as can be seen from
these old bushes.

TENDER WORKING PARTY
 


 
Our gas cylinder trolley has completed is overhaul
 and is now resplendent in a coat of engine green

 
The three brake beams have been re-bushed where necessary
and friction washers added. These now require the top hat bushes
on the beam ends. Just another 12 bushes of the 70 plus 
                                              required to complete the brake rigging.

 
New pins and bushes for the brake hanger brackets
underway

 
One of the heavy components of the brake rigging
is the weigh bar shaft which fits beneath the front
end of the tender. This shaft is in particularly poor condition
requiring sleeves on both ends and new bushes and pins.
 

                                      The removal of the old bushes where the beam connects
                                      to the pull rods and adjusting screws proved to be a lengthy
                                    task as in a previous life the bushes had been welded in place.
                                    Six hours on and a few choice expletives and the four bushes
                                    finally succumbed. The faces now require the weld removing
                                              and yet more bushes and friction washers made


 
The new pin in place that connects the shaft to the
vacuum piston rod 

 
and a new pin for the hand brake connection. The
corroded condition of the one end journal can also be seen.
That will have to wait for another day!

                                                        TENDER WORKING PARTY

 
    With the recent humid weather and rain, some much
needed gardening was undertaken to clear the prolific vegetation


                              Another casualty of the damp conditions was the gas cylinder trolley
                             where the base framework had corroded through - some TLC and
                                                   welding will soon restore it to service

 
    In amongst the gardening and equipment repairs, work continued
   on the tender brake gear as the adjusting screws were cleaned
 and dismantled for inspection

31st May 2014 - Midlands Site


                                    Hi folks - long time since we were in touch regarding
                                    Dinmore Manor's new tender but with the locomotive
                             now operational, attention has turned once again to the tender.


                                     A very stubborn pin on the intermediate brake beam had
                                     resisted previous attempts with a propane torch to free it
                                   and major surgery was required to remove the offending pin

 
 The thread was first cut off the pin and the shank was
   then drilled to leave a thin wall. The drilling produced
 a blind hole which allowed a punch to be inserted in
 the hole and a large 'knockometer' drove the pin out.
The remains of the two halves of the pin are seen
 alongside the link it once retained.


                                   The four pull rods are seen with the new pins inserted.
                                  The pins have been drilled with grease lubrication holes
                                                   to reduce wear and tear in service.

                                                              TO BE CONTINUED

17th May 2014 - A Day to Remember


                        
                                For the first time in preservation, two operational locomotives
                                of the Dinmore Manor Locomotive Group were paired up to
                      double head service trains on the Gloucestershire Warwickshire Railway


                                    7820 and 3850 run round their train at Toddington Station

 
The locos have a 'splash' of water at the column at Toddington

 
    Having reversed their order, 3850 leads 7820 as they
depart from Toddington Cheltenham bound
