Photo news

Here are a few photos of recent progress on the construction of the new tender chassis and tender tank – the pieces of the jigsaw that is the restoration of 4123 are starting to get bigger…

Hopefully the photos and the captions do the talking.   If you’d like to see more photos of how this is coming along, have a look at our Flikr page.

Elbow machining

One of the new castings for the tender water feed elbows is machined on the lathe. Here it is having the 11 TPI screw thread cut.

Scoope Dome 1

This is the ‘dome’ for the water scoop filler pipe, which sits at the back of the tender, and is a distinctive feature of those tenders that were fitted with water scoops (i.e. all the 4Fs). This is a combination of new metal (the lower barrel and angle) with a re-used original top section which was repairable, and which would have been very difficult/expensive to replace with a new item.

Filler Lid

Here is the new tender tank water filler pipe and lid. Later LMS tenders had a hinged lid, but 4123 always had a ‘loose’ lid which was attached to the pipe with a chain (to stop it getting lost), so this is what we’ve replicated. We didn’t have an original to copy, so the profile for this had to be scaled from a drawing to get the correct radius and height, etc. This was ‘metal- spun’ for us by Purdies of Bradford.

 

tank parts

This pile of bits are components of the tender tank which are fitted inside and outside of the ‘well’ on the bottom of the tank. These have now been welded into position into the well. The two new gunmetal castings for the water feed elbows can also been seen – having been fully machined – and these are now ready to fit to the tank when the time comes.

Tank stiffeners

Here are some more tender tank internal components waiting to be installed. The red plates are vertical stiffeners which form part of the main structure of the tank, and to which the main internal cross-baffles are attached.

Well 1

Here is a view on the newly fabricated tender tank ‘well’. This fits underneath the main body of the tank, between the inner frames of the chassis, and provides a useful additional ~500 gallons of water capacity. We have made this from one piece of plate folded to the correct shape, and with end plates welded in. Doing it this way has removed around 300 rivets from the tank.

Well Fabrication

A close-up of the end plate of the well after welding was completed and ground flush. Originally this would have been a riveted plate, but welding is easier and more cost effective, and will never be seen once the tank is installed on the frames.

Here's a view on the underside of the tender well showing the various attachments which have now been welded on.   Don't let the rusty finish worry you - this will be grit blasted once the tank fabrication is completed, and then coated with a decent paint system, so it will hopefully last for many years.
