Cylinders

Cylinder’s Pressure Tested

This last weekend saw our team finish the pressure testing of the cylinder castings to 250 psi hydraulic. We can now proceed with drilling and tapping to prepare for the fitting of the pistons and valves. A big step forward in completing the ‘bottom end’ of the locomotive. Preliminary fitting of the cylinder cladding was carried out too.

Cross head Fitted

A great weekend working on Betton, pleased to report that Llangollen Engineering have fitted the first crosshead to be seen on a Grange in over 50 years, further significant progress saw the fitting of the front cab window frames, the sanding gear operating arms and the firebox crinolines.

As ever grateful thanks to all our volunteers, Robin, Rich, Colin, Mick, David, Max, Maverick, John, Lynn and Chris for being our morale booster, as well as cracking the whip!

Willington’s Boiler stripped ready for quotes

Chris and the Team worked remarkably hard this weekend, finishing off removing the tubes from the boiler. Here we see some remarkable shots from inside the boiler, which has now also had its tube plate partly removed. Meanwhile the wheels were re-painted ahead of re-wheeling and further holes drilled in the cylinders ready for the cleating. Many Thanks to everyone, Chris,Colin, Richard P, Quentin, Mick, Barry, Max, Bill, David and Lynn. Also saying a fond farewell to Max who is returning to the Carribean (see you next year!)

Working weekend 29-31st August

A strong team of 9 members worked over 3 days on further construction of the platework at the front of the locomotive around the cylinders. The cutting and trimming of panels and the drilling of the many bolt holes kept the team busy working in 2 different groups. Additionally the complete reverser assembly has been assembled. The parts needed for the cylinder drain cocks have been manufactured along with the front sand boxes. Further work included the start of the fitting of the brake hangers and the preparation of the valve covers for trial fitting. Good progress by our enthusiastic team as the locomotive takes shape.

At  this weekend’s working days two photographs illustrate the progress made.

First the top coat paint on the fire iron tunnel and integrated splashers and secondly the trial fitting of the valve and piston end covers.

Other work included a further inspection of Willington Halls boiler to evaluate the work needed.

New Fire Iron Tunnel

A new fire iron tunnel has been fabricated for 6880 incorporating the two rear left hand splashers. The tunnel houses the long irons used in maintaining the fire and during disposal.

Other work at last weekend’s session was the fitting of the end studs to the cylinder castings

6880 Gets its Cylinders

image Betton Grange received its cylinders this week, after the successful casting and machining over the past 2 months.

Around 40 members attended Llangollen on Sunday 15th February to inspect the progress made, followed by a run along the railway to Corwen and back with Prairie tank 5199.

imagePreparations are at an advanced stage for SSS4 now only 3 weeks away.
