Reverser links, cylinder cocks, sheaves and blast pipe!

 We have completed the connection between the reverser and the valve connecting rods and attached the 2nd plate under the cylinder block. This still has to have a finishing coat of paint - colour to be decided. It's black. The cylinder cocks shaft has also been fitted. The eccentric sheaves have been painted in signal red but 1 original set was damaged and we managed to get a replacement. This is getting some remedial attention as you can see from the photos. The long bolts required heat to extract them and the ones in the damaged set, which are good, will be used. A replacement blast pipe has also been aquired. Both big ends are ready for grit blasting, tinning and white metalling.

2nd plate inserted. A paint job next but what colour? Turns out it's black!

It can't deny Alan & Nick! It came out.

Valve connecting rods

 After publishing an update yesterday I thought this very important move forward deserved its own page! The valve connecting rods, along with the radius links were put into the frame on the 30th January and is the first part of the motion that will make No 9 a living, breathing engine. A lot more connecting to do but a big step in her restoration. Also a photo of the cottar pins securing the slide bars, each one a different size. Well done Alan!

Plates and painting and motion preview!

 The cylinder block that we worked on last month needs protection and insulation both top and bottom and plated were cut, using the old ones as templates. The top plates were easier than the bottom ones as they already had the tapped holes for the bolts. On the bottom new holes had to be drilled and tapped, a hard job pushing a drill up into cast iron! And 1 tap down - sorry! That done insulation was cut to "size" and held in place while the plate was moved into place. The left hand plate on the bottom still has to be done and heat resistant paint applied on all some surfaces. Brian has continued the painting work on the buffer beams and the frame, making it look very smart! We also started work on the motion by doing some positioning work on the reverser weigh shaft. This for the next blog coming soon!

Eccentrics, concrete and oil!

 The last few days of 2024 and one of 2025 were busy with eccentrics and straps, preparing the big end bearings for new white metal, and to clean out old oil. See the video section for some oil being expunged! The top of the cylinder block was filled with concrete. This protects the block from damage as we found water ingress when we were dismantling her. Plates will go on top of this also. The cylinders were cleaned out and oiled to protect them, and the eccentrics painted and put back on the driving axle.The eccentric straps were gritblasted, one showing the LI and 7097 markings, which, along with all the parts of No 9 prove their originality.

To be correct all the bolt heads are aligned and the buffers are back on! A good start to 2025!

Boring the cylinders on No 9.

 The cylinders on No 9 needed boring as they had become worn after many years of hard work. There was a score line in the RH one which required skimming. N.L. Engineering Ltd came up from Wigan to do the job. They completed the work over 3 days between the 3rd & 5th December. The boring machine is an amazing piece of kit and John and Jake have done an excellent job. The cylinders are as smooth as.........! There are some videos in that section of the Blog for you to enjoy. Apologies for the length of this Blog but it is a very important part of No 9's restoration. Most of the photos credit Jake Morrow.

To start the covers on the rear of the block had to be removed. The nuts looked as if they were going to give trouble but after heat was applied to each a sharp tap from a hammer released them!
