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.

The connecting rods are laid out ready for refitting of the big end bushes
The outer face of the connecting rod has been re-metalled and the bush bored ready to fit to the rod
The coupling rods have been similarly refurbished and are ready for the completed bushes to be fitted
Parts of the brake gear which require attention are laid out alongside the rear coupling rods


The smoke box door has been rubbed down and another coat of heat resistant paint applied to give the door a very acceptable finish

With Tyseley closed as a Vintage Trains tour was scheduled for the Saturday, the working party had a day off. Our illustrious Treasurer speeds through Abergele and Pensarn with some assistance from 5043 Earl of Mount Edgcumbe on the Welsh Dragon en route to Holyhead

Saturday 10th August 2013 - Tyseley Locomotive Works

The heavily worn damper crank spindle, which had been welded to the mainframe, required replacement


The replacement spindle with the re-bushed crank levers for operating the linkage to the damper doors is ready to fit to the locomotive
                                                Cladding and Boiler Fittings

Rubbing down of the cylinder cladding, handrails and cab pipework continues so that as much as possible is ready for the return of the boiler


                The cylinder cover cladding is rubbed down in readiness for a further coat of paint

                                                            The Chassis

Is there anybody down there - Mark, not in the most comfortable of positions, sorts out the copper pipe runs for the vacuum brake system
Bob commences the all important task of fitting split pins to those parts of the motion that are now fully assembled. The return spring on the weigh-bar shaft has also been adjusted and a split pin fitted
Kenneth, doing a good impression of a Russian cosmonaut, wire brushes the rust off the new smoke box barrel.
Mike, deep in thought, pauses from his labour of applying a coat of heat resistant paint to the smoke box barrel.
Mike puts his early training as a gynaecologist to good use.

The finished article
Brake Gear
The brake gear is laid out to assess what further work is required to complete it.
Life would be so much simpler if steam engines had disc brakes (preferably with ABS)

If I do a castling with my queenside rook, I reckon that it will be checkmate! The business end of the brake gear where the front cross beam compensating links attach to the brake adjuster screws and finally to the brake cylinder shaft is temporarily assembled.

                                                                     Valve Gear


With the problems arising when the gear was dismantled from incorrectly marked components, the eccentric straps and rods have been erected to complete the assembly of the valve gear.

Connecting Rods

With the rod under the press, a start can be made to get the big end bush out
Spacers are arranged to push out the bush
Everything ready for the first press to break the seal on the bush
Hold tight - here we go!!!
The bush almost out

The bush brass is now ready to have the old white metal removed and then re-metalled, machined and
                                              fitted back into the rod - simples!

Rods, bushes and gudgeon pins which will shortly be performing the task they were designed for.
Smoke Box Components
Meanwhile in a galaxy far, far way a new petticoat spinning has been fashioned to fit the new blower ring casting
With the petticoat and blower ring assembled, it is ready for a trial fit to the later style of Manor chimney fitted after the redrafting of the mid 1950's which transformed the steaming capabilities of engines once renowned for being shy on steam.
