Here is my brief Report, following the March 'Volunteer Session':

The Frames for the Locomotive are still away, being cleaned and painted. Two of the three sets of Driving Wheels are ready in the Works. The third set of Driving Wheels (the centre, 'crank axle' - which is driven by the Middle Cylinder) is off-site to be 're-tyred'.

The frames for the New Tender have been hot-rivetted.

Our first task was to move all of the existing casing sections, removed from 'Squadron'. These had to be carried from storage, on the upper level of the adjacent building, into Herston Works. Whilst almost all of the sections are 'scrap', they will have some use in being the 'templates' for the new sections. For the few sections which were of use (mainly the small sized panels) we removed the old rivets/bolts and cleaned the sections up, ready for painting.

Unfortunately, 'Sir Keith Park' had suffered a cracked left hand cylinder rear cover at the Severn Valley Railway. Therefore, our priority was to assist in the refurbishment of a replacement cover which one of our Volunteers, who lives in Bewdley, could take back to the SVR, in the boot of his car when he returned on the Saturday. (The good news is that everything went to plan and SKP was back to normal that same day).

The following day, a group of us worked on cleaning up the existing six sets of Axle Boxes and components, for the New Tender. Meanwhile, the highly skilled task of 'white metalling' the bearing surfaces for these Axle Boxes was being carried out in the Workshop.

The Oil Sump (the oil bath for the chain driven valve gear) was also cleaned up.

The return of the Locomotive's Frames will release a vast amount of work (following re-wheeling) in reassembling '257 Squadron'.

I will be unable to attend the next Volunteer Session in April. However, as always, I will keep you up to date with all the 'goings on' from my colleagues at Herston Works.

The Front and Rear sets of Driving Wheels for 'Squadron' are in the Works, painted and ready for the return of the Frames. The Middle set (the 'Crank Axle') has been at SDR Engineering in Buckfastleigh' for re-tyring. Here are some interesting pics of this procedure (Pics 61 to 73 incl):

Very nice photographs and video. I now have an idea of what will happen with the wheels of 82045 when they receive their tyres.

Unfortunately, I was unable to attend the April 'Volunteer Session' at Herston Works. However, courtesy of Southern Locomotives Ltd, here is the link to the 'Restoration 2013' section of the SLL Galleries. Pics 74 to 81 incl show some of the work that was carried out:

Have you missed me?????? (Mama Wedgy and I have been away for a few days, hence the reason why it has been a bit quiet at this end).

I will be attending the May 'Volunteer Session' at Herston Works next week, so I will report back afterwards regarding the activities/progress on 34072.

Here is my brief Report, following the May 'Volunteer Session' at Herston Works:

At the moment, it is a typical case of 'the lull before the storm'! Work continues on the Cab and the Frames, etc for the New Tender, together with the ongoing manufacture of the many new parts and components required. However, when the Frames of the Locomotive return (currently delayed, I understand, by the inclement weather - as the cleaning, painting, etc of the Frames are all outdoor activities) the Frames can be Re-Wheeled and the 'rebuild' of the Locomotive can commence, from the bottom up.

Southern Locomotives Ltd also had a Workshop at Bitton, but this has now closed (due to retirements, etc) so all the Stock is being moved to Herston Works, including (literally) thousands of nuts, bolts, spring washers, flat washers, together with numerous drill taps, dies, etc of differing standards (BSW, BSF, BSP, BSPT, etc, etc).
So, a Group of four 'Volunteers' (myself included) had the delightful task of sorting out the various boxes into the appropriate diameter, length and type, before adding them to our existing 'stock'.
Some of the drill taps (helpfully) had the standard (eg: BSW), size and tpi (threads per inch) stamped on them. Others, unfortunately, had to be classed as 'Unknown' due to the absence of any identification. Yours truly, therefore, had the task of identifying these items by (a) using 'thread gauges' which are similar to individual 'feeler gauges' (for checking the gap on a spark plug, say) but these are 'serrated' to give various tpi thread profiles; (b) measuring the 'major' diameter of the thread on the tap (using a 'Vernier Caliper' - a very precise measuring instrument) and (c) checking a Data Book of the various thread types to determine, from (a) and (b), exactly what type and size of drill tap we were looking at.
Over the two days, we cleared virtually all of the nuts, bolts and washers, etc and made a good start on the drill taps ('work in progress').

Also whilst we were there, the Front Bogie of the Locomotive was Re-Wheeled.

The photos of the above activities, etc are all on the link below (Photos 82 to 113 incl.):

https://picasaweb.google.com/1168391414 ... 1197542082

These also include some fascinating photos of the 6'-2'' diameter, Centre Driving Wheels of 34072 being profiled on the massive Wheel Lathe (following the recent Re-Tyring of the Wheels) at SDR Engineering, Buckfastleigh.

There is also a short video of this process (you will be amazed):

The frames of 34072 257 Squadron have been cleaned and primed, and are back in Herston works. The long task of rebuilding the loco can now commence.

With the Frames now back at Herston Works, we can really get on with the job in earnest. Next 'major' task: Re-Wheeling the three sets of 6'-2'' dia Driving Wheels, following painting the Frames (Black) and the installation of the Horn Guides (to accept the Axle Boxes on the Driving Wheels).

Yes, unfortunately, the shortage of 'steam coal' in this Country and also, the Volunteers to run the Heritage Steam Railways, there is a real threat to the future operation of these Railways. There is plenty of coal available from abroad, but at an increased cost. This means Fares will have to go up, which may put people off coming to the Railways, especially in these austere times.

As regards Volunteers, us existing members tend to be mainly of a 'certain age' and desperately need some 'young blood' to join us, get involved and give some hope for the future.

I thnk a lot of the reason for that is younger people tend to be very busy with family and work commitments which is why you usually see older volunteers at work on the loco's however I know quite a few younger people interested in steam but lack the spare time to do anything. :)

I was unable to attend the June 'Volunteer Session' at Herston Works. However, courtesy of Southern Locomotives Ltd, here is the link to the 'Galleries' section of the website showing the work that took place (Pics 121 to 146 incl):

https://picasaweb.google.com/1168391414 ... 2982000914

There are some interesting pics showing the unique, chain-driven mechanism that operates the Valve Gear on the 'original' ('unrebuilt') Bulleid Pacifics. One of Oliver Bulleid's 'radical' designs, totally discarded when a number of these 'Southern Railway' Locomotives (eg: 34053 'Sir Keith Park') were rebuilt by British Railways.
