The January 'Volunteer Session' took place recently at Herston Works. Unfortunately, again I was unable to attend this Session. However, Southern Locomotives Ltd have posted some pics on the website. These include:

a) Some pics showing the process of aligning the axle boxes with the cylinders, before the 'Re-Wheeling' is carried out.

b) Some pics showing the progress of the 'Boiler Restoration/Repair' work, being carried out 'off site'.

Here is the link (Pics 1 to 28 incl):

There was a 'Volunteer Session' at Herston Works in February and which I was not able to attend (I do hope to be able to get to the next one, in April). A few photos have been added to the Southern Locomotives Ltd website, as shown on the link below (Pics 29 to 34 incl.):

Money permitting, the target is to have her running by September 2015: the 75th Anniversary of the Battle of Britain (this being a 'Battle of Britain Class' Locomotive).

Well spotted Robert. My only excuse is that I posted in haste and have now corrected 'May' to April (or perhaps it was yet another 'Senior Moment' ;) ). The year is going fast enough as it is!

I must apologise to you all that I have not yet been able to give you my Report and pictures of all the latest 'goings on' at Herston Works. It has been 'all go' here since I returned from Swanage, plus a few PC problems into the mix as well (now sorted, I hope!).'Normal Service' is now returning and I will let you have all the info' as soon as I can.

Here is my brief Report (and some photos) following the April 'Volunteer Session' at Herston Works, Swanage:

Three of us were given the task of working on the existing Spring Hanger Bolts for the Driving Wheels of '257 Squadron'. There were a total of 12 steel bolts (1.75'' diameter) plus 2 large nuts and a plate, off the Locomotive (2 assemblies per spring, for each of the 6 Driving Wheels). The nuts had to be removed and then each item (nuts, bolts and plate) thoroughly cleaned. This was quite a task, considering that most of the nuts were well rusted on!
Thankfully, out of the 24 nuts, there were only 3 which simply refused to budge, despite all efforts - including the application of heat. So these had to be cut off with an angle grinder and scrapped. Even then, these nuts didn't yield without a fight! Another case of a lot of work involved, but not a lot to show for it at the end. All part of the 'Joys of Steam Locomotive Restoration', as we always say.

Other work being carried out at the time included:
- Re-fixing the existing, cleaned, copper lubrication pipework to the Frames, for the Axle Boxes, etc. Each section of pipework being annealed (heated up and then quenched in water) before fitting.
- Cladding work to the Cab.
- Preparation work for the fitting of the new Axle Boxes for the Driving Wheels.
- Refurbishing of the 3 Mechanical Lubricators. (These will be refitted to the Running Plate and pump oil to the Axle Boxes, etc.)

Here are the pics (my grateful thanks to Roger Hughes for the use of these photos):

8 out of the 12 assemblies 'dis-assembled'. All the bolts will be sent for 'Non-Destructive Testing' (NDT):

That is a stunning picture for an idea of scale - didn't realise the wheels would be THAT big ... even the width of them is astonishing :-o

It's certainly BIG engineering :D :D :p

Thank you, Robert. As usual, it's the Middle cylinder which seems to have the problems!

Yes Dougs, it was certainly also a bit of an education for me when I first started getting involved, in a practical 'hands on' way, back in 2009. I thought I knew about most of the things that make a Steam Locomotive function. How wrong I was! I'm a lot wiser now. ;)
