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!

The nearly finished job. Just the removal of the skimmimg to do!

And a wee reminder of what they were like!

Wheels, brakes, slide bars and underkeeps!

The big news is that the wheelsets have arrived back from Riley & Son. All 4 brake shafts have been put in place with the leading one having to be lowered down between the newly inserted slide bars. Ah - the story unfolds! Work on boring the cylinders by N.L. Engineering on the 3rd to the 5th December meant that the slide bars, along with the rear cylinder covers, had to be removed. Aligning the axle boxes with the wheelsets was completed successfully and the buffer beam cleaned, along with all the bolts and nuts. New underkeeps have arrived and are now being soaked in an oil bath. A separate post will follow with info about the boring of the cylinders.

Wheelsets returned on the 14th November! John And Alan checking them out!

Buffer beam wirebrushed along with frame and primed. Cylinders now accessible for boring.

Some of the beams bolts gritblasted, primed and run through a die.

New underkeeps. Look good enough to lay your head on! Now soaking in an oilbath ready for the axlebox, not the head!

Wheelsets primed and undercoated, ready for the 20-C-40 Midnight Blue.

                                            

Paint, paint, axle boxes, slide bars & more paint!

 Another productive month with the inside frames getting a signal red finishing coat and the outside a 1st coat of NCB Midnight Blue. The brake cylinder, put back in place, will be fitted with the insulation and new cover.  Axle box trial fitting and the 8 slide bars was completed with lots of measuring for both, and shims being fitted. All the slide bars, along with their bolts, were all marked. This allowed for easier fitting. The front buffer beam has been removed to allow the boring of the cylinder(s) and this uncovered some areas needing cleaning. We don't know when this had been removed before (probably before arriving from NCB in 1976) but the bolts had been put back in the wrong way round!

A variety of new advances!

 Over the last month or so the remaining reaming to the frame and the springs etc has been completed and the reverser weighshaft has been returned to the frame. After trying to source new angle (26ft + long x 2) for the running board supports, the original ones have been repurposed, needlegunned, primed and undercoated. Brake rods have also been refurbed and are all in good condition. The brake cylinder, which we put back on the frame, had to be taken off to attach a cover for insulation. Robin Taylor has been making all the pins for the springs, the old ones were past their sell by date! Part of the inside of the frame has been given a 1st coat of signal red and looks great - another step forward. One other big step forward is the wheelsets have been sent to Riley's for re-tyring etc. They arrived there on Tuesday 1st October. Thanks to Nathan for getting that through!

Brake shaft back in!

 A day to celebrate as the first major piece of the No 9 jigsaw is put back in place. The brake shaft was lanquishing in the shrubbery at the back of the Shed since its removal on the 3rd August last year. Needle gunned, primed, protected with a coat of light grey and greased up ready for its return to the frame, Alan Nick and I, with support from Rory on the telehandler, raised it up on the gantry and lowered it into place. Adjustments by podgers and the bolts were secured in place. The moment the shaft swung down on the bearings when I tightened the last nut was very pleasing and satisfying!
