Summer engineering update
In June a few select volunteers restarted stripping down work on GSN. Numbers are being strictly limited to begin with to comply with social distancing so it may be a little while before we can welcome new members to our working parties. Thank you to those that have recently sent in their volunteer forms to join the ranks of our working members, we will welcome you to Blunsdon as soon as we are able.
Most of the work focused on getting our container set up which included the installation of the container lights and electrical sockets, at the request of the railway painting the outside green and various other small tasks. Work did progress on the locomotive with the removal of the springs that attach to the centre driving wheels. A preliminary visual inspection suggests they are good condition considering their age.
Although we await the installation of a permanent electrical feed, we have a temporary connection to our newly installed consumer unit to give us both lighting and a ring main in the container. We have included RCD protected sockets for external tool use, sockets by the desk including USB charging points and sockets for the kindly donated microwave oven, fridge and kettle!
The stripping down also saw the right hand side piston and cover being removed. These have now been put into storage and will their condition will be assessed.
The Society is happy to report that it was able to purchase some new components for the locomotive in the form of a Speedo drive, cut off indicator quadrant & part of the steam turbo generator. The components were from an enthusiast’s collection who offered them to the Society for an incredibly reasonable price.
Work in July was mostly focused around preparing for the boiler lift with some of the more troublesome boiler mounts being removed. The front boiler mounts proved especially resistant to being removed but after some head scratching a plan was devised and carried out that saw the mounts being separated.
The main engineering highlight for this issue was the new front end casing which was successfully test fitted in July. The casing was originally built to be a surprise for our members at the cancelled AGM earlier in the year. The casing was built by the team at Leaky Finders who did another fantastic job for us.
The two outside pieces are slightly bigger then they were originally built, we felt it was a sensible decision to make them bigger then we need to allow us trim them down during their final fitting and make a perfect joint to the rest of the casing. For the same reason none of the fitting holes were drilled, this meant we had to use some wooden props to display the pieces on the locomotive. The most complex part of the casing manufacture was the lamp irons which required machining to get the side profiles right before beginning to be bent into their into the final shape.
The “Sponsor an inch or more” campaign that was masterminded by Graham Muspratt was a huge success with the Society raising just under £2,000. The Society would like to thank Graham and all those who donated to the appeal. Getting the funding in place so quickly has made the planning for the boiler lift far simpler. At the time of publication a date has been agreed for the lift prior to the rearranged AGM although for health and safety reasons the Society will not be publishing the exact date.
With the relaxation of lockdown rules our volunteers have been hard at work preparing for the boiler lift. Our aim is to get all the remaining small boiler tubes cut and removed from the boiler before the day of the lift. The majority of the securing bolts have been removed with the remaining ones being left in for safety reasons. Our volunteers will remove all the final securing bolts the day before the lift.
The Society have been debating the possibility of removing both the trailing truck and front bogie whilst the crane is on site for the boiler lift. The agreed plan is to attempt to remove the trailing truck but we’ll leave the front bogie in place. There are several reasons for this decision with the main factor being the Society is not in a position where we can make the locomotive immobile. The weight of the front end of the locomotive would require us to pack behind the bufferbeam in order to prevent the possibility GSN pivoting on her front drive axle. If GSN had a crank axle in place along side the rear drive wheel would have created a counter weight to balance the locomotive without either the bogie or trailing truck needing to be in place. The safest option we are taking is to remove the trailing truck and leave the bogie in place as this will allow us to push the locomotive back under cover once the lifts have been completed.
All the generous people who donated to the appeal will be entered into a free draw to win a number of prizes, including: a star prize of a Graham Farish N Gauge Merchant Navy Pacific locomotive, a years free membership to the GSNLR society, GSN merchandise and other prizes.
The raffle will be drawn at random at pivotal points during the boiler lift such as: The moment the first inch has been lifted, point of maximum lift, being clear of the chassis and then lowered to its new location. If you have donated and not contacted us to confirm your raffle entry with us please do at the earliest opportunity in order to ensure you don’t miss out.
How you can help us.
With so much engineering progress being made with the restoration of 21c11 / 35011 back to original condition complete with air smoothed casing and chain drive valve gear you can help us in several different ways:
The General Steam Navigation Locomotive Restoration Society Membership costs £12 for the year click here for more details on how to join us.
The General Steam Navigation C.I.C. offers our supporters the opportunity to purchase shares in the locomotive. To find out more about becoming a shareholder and the levels of benefits click here.
No matter what skills you have we can use your help. Please contact our volunteer liaison officer Mr Andrew Collett at firstname.lastname@example.org. If you are considering a donation to the project or buying some shares today is the perfect time to do it.
The project is heading into some very exciting times and any financial contributions would be greatly appreciated.
As always thank you for your continued support.
